How to Use Arduino Protoshield?

Arduino Protoshield is a great way to prototype your Arduino projects. It allows you to easily connect your Arduino project to the real world by providing an easy way to connect sensors, motors, and other components. In this article, we will answer some common questions about Arduino Protoshield and provide some tips on how to use it like a pro!

What is Arduino Protoshield

The Arduino Protoshield is a device that allows you to easily connect and control various components on an Arduino board.

It consists of two main parts: the shield itself and a base plate, which connects all the components together. The shield also has an array of pre-made supporting circuitry, such as current limiters, voltage regulators, and other electronics to allow you to use your Arduino project with ease.

Typically, it is used in combination with a breadboard or prototyping PCBs for creating larger projects. By using this device you can quickly assemble and debug circuits. In addition to the convenience factor, there are numerous other reasons why people choose to use the Arduino Protoshield instead of just wiring it up manually.

All in all Protoshield does a great job at extending the functionality of the Arduino and making it even easier to use. [1], [2]

How to Assemble and Connect Arduino Protoshield

Connecting an Arduino Protoshield is fairly straightforward and easy thanks to its intuitive design. In this section, we’ll go over the steps necessary to connect a Protoshield and assemble your project. We will showcase how to do it on a v25 version of the Protoshield.

Hardware assembly

The first step is to assemble the Protoshield hardware. But before that, you should inspect your kit to check if everything is included and works properly. The Protoshield kit should include the shield itself, all the necessary pins and connecting wires, resistors, and other components. After you have checked that the kit is complete, it’s time to assemble your Protoshield.

Besides the shield kit itself, you will also need some tools to assemble your project. This includes a soldering iron, solder, and wire cutters or strippers. If you aren’t familiar with soldering, it’s completely fine, as the Protoshield doesn’t require any complex soldering.

We suggest you start by soldering the smaller parts first, such as the resistors and pins, and then move on to the larger components.


Resistors are one of the most important components in any Arduino project as they limit the amount of current that flows through a circuit. The Protoshield kit comes with three resistors that you need to solder onto the shield. Be sure to double-check that each resistor is soldered in the correct place and labeled correctly, or else your circuit won’t work properly.

There’s little guesswork involved here as resistors will go into rectangular boxes labeled with the value they are intended to handle. The Protoshield’s accompanying documentation will also tell you where each resistor should go, so be sure to consult it before soldering them.

To make the job easier, you can slightly bend the resistor legs before soldering them. This will ensure that they make a strong connection with the board and won’t move around while you’re soldering.

When sticking the resistor into the board, double check the correct value of the resistor. Luckily, you won’t need to worry about the polarity as the resistors are non-polarized components.

Then, bend the legs of resistors again in such a way that it holds the resistor in place. Finally, solder the legs of each resistor securely to the bottom board. Repeat this process in exactly the same way for all the other resistors in the kit.

When you are done, cut the remaining parts of the legs off with wire cutters. This will keep the shield neat, organized. Just be sure not to cut the legs too short, as you still need to be able to remove them in case anything goes wrong and doing so can weaken the joint.


Next we move on to the capacitors. Capacitors are used to store energy and can be found in almost all electronics projects. Like resistors, capacitors also come with their own marking that specifies what capacity of current they should handle. Protoshield comes with two 0.1uF capacitors, which should be soldered onto the board. Same as resistors, capacitors are non-polarized and therefore can be used either way around.

Capacitors should be placed in a rectangular box with a line in the middle. There’s two of these on each side of the board. Contrary to the resistors, there’s no need to bend the legs of the capacitor to make it fit in.

Once you stick them in however, you will need to bend their legs and solder them. Like resistors, you should apply a small amount of solder to both the leg and the hole in order to properly secure it. Make sure that they are placed in the right orientation before soldering.

Once both capacitors are soldered, cut the remaining part of the legs with a wire cutter. Again, this will make sure that the board is nice and clean and the wires won’t be sticking out.


Another crucial component is the LEDs. These are used to light up whenever a signal passes through your circuit and can be very useful when debugging or troubleshooting. The Protoshield comes with two white LEDs, but you can use other colors if you like.

When placing the LEDs in the board you will be working with polarized components for the first time. LEDs will have two legs of different lengths. The shorter leg is the positive side called the cathode while the longer one is the negative side and it’s called anode.

When inserting the LED into the board, make sure that the legs are placed in their corresponding holes as indicated by the accompanying documentation. The LEDs should go into a semi-circular footprints on the board, one of each.

Smaller legs of the LED should go into a hole near the flat part of the semi-circle. Once in, flip the board over and bend the LED legs slightly to make sure that they don’t come free while soldering. Then, solder them securely and once done, cut the remaining part of the legs with a wire cutter.

Finally, repeat this process for the other LED on the board. Make sure that each one is properly oriented before soldering them into place. You can use a multimeter to double check the orientation if necessary.


Buttons are also essential components in electronics projects. They are used to give input signals to the microcontroller, which can be used for many different purposes. Protoshield comes with two buttons but you can use more if needed.

The placement of the buttons is pretty obvious, these should go in the remaining empty areas on your board – the square footprints with small circles in the middle.

Contrary to the previous components, buttons come with four legs. And it’s pretty simple to place them correctly as they are non-polarized. You just have to make sure that all four legs fit into the corresponding holes.

When you insert all the legs, press down slightly to make sure that the button stays in place. You should hear a few clicks when you do. After that, flip the board again and solder all four legs. Once done, cut the remaining parts with a wire cutter for a neat finish. Repeat this process for both buttons on the board and you are pretty much ready to go.


Finally, you will need to attach the headers. Headers are necessary for connecting your circuit board to other components that use pin headers such as sensors or servos. The Protoshield comes with four headers with different amounts of pins.

Each header has at least two locations where you can attach them on your board. No matter which location you settle on, be sure to place the header into the outermost holes.

For six-pin headers, you want to insert these on top of the board. Once you inserted a header, turn the board over and solder the edge pin. Make sure that the header is completely parallel to the board before soldering.

If everything seems in order, return and solder the pin on another edge. It’s also a good idea to plug in the Arduino and perform the alignment test before soldering the other headers. This will ensure that the header is correctly placed and aligned with the board.

Now take the two eight-pin headers and insert them in the other locations on your board. Again, make sure to place them in the outermost holes to make the prototyping easier. The process is very similar to the one for six-pin headers. Flip the board over, solder edge pins and then check the alignment with Arduino again.

At this point it’s a good idea to try attaching the shield to your Arduino. If everything was done correctly, you should see no issues in attaching it. If you encounter any problems, make sure to go back and check the orientation of your headers. With some patience, you can get everything right in no time!

Once everything is in order, you can return and solder the remaining twenty pins. And when done, you should be ready to start prototyping with your Arduino Protoshield. [1], [2]

Perform a final check

Now you should have everything attached and soldered, but it’s important to perform a final check before powering up your board. Make sure that the orientation of all components is correct and that the components are firmly attached to the board.

All the solder joints should look shiny, smooth and solid. If you see any dull, fuzzy or broken solder joint, it’s a good idea to reflow the pin and check again. This should ensure that your board is ready for prototyping.

Look for any solder bridges and make sure that everything is clean and in order. These can happen when two pins are connected by a small amount of solder and can cause shorts in your circuit.

If everything checks out, you can finally power up your board and start building amazing projects with it! Now your Protoshield should look something like a populated PCB with all its components in place. You are finally ready to connect to the Arduino Uno Board and start tinkering with electronics projects!

Wire everything up

But wait! Before connecting your Protoshield to the Arduino Uno, you need to wire everything up first. The Protoshield needs to be wired to Arduino in order to be able to communicate with it.

You may notice a few through holes labeled as JC1, JC2 and JC3 on your board. These are related to the button and LED components. You need to connect one wire from each pin of the button or LED to its respective through hole on the board. Luckily, it doesn’t really matter in what manner you want to connect them, as long as the connections are firm and are connected directly to Arduino pins. [1], [2]

Fill the prototype board

Of course, you will also need to fill the prototype board with components and wires. This is where the fun begins! You can start building your own circuit designs by soldering electronic components onto your Protoshield. How you go about it is completely up to you.

You can solder components directly onto the Protoshield, or use jumper wires and a breadboard for more complex designs. With some patience and creativity, you can start building your own awesome projects with Arduino Protoshield in no time!

You can also place a breadboard over the Protoshield to create a larger prototyping area. This will give you much more space for components and wires, allowing you to build even bigger and better projects. Just remember to make sure that connections are secure and that everything is connected according to the circuit diagram.

Once everything is connected and wired up correctly, it’s finally time to attach your Arduino Uno board to your Protoshield. This will enable communication between both boards and allow us to test our circuit designs. Now it’s time to get creative and come up with some amazing projects! [1], [2]
