Now that you know some of the benefits of the Raspberry Pi, let’s explore a few of its amazing car projects. In this section, we’ll take a look at some of the best projects and how they can be used.

Simple Bluetooth Controlled Car

The Raspberry Pi provides a convenient way to control and program a car using Bluetooth technology. You can use the onboard Bluetooth of the Pi and connect it to your smartphone or other device, allowing you to control the car from your device.

To get started with this project, you will need a few items:

  • Raspberry Pi Pico + Header Pins + Cable
  • L298N Motor Driver Controller Board
  • 2 x 18650 Battery Storage Box Case
  • DC Electric Motor with Plastic TT Motor Tire Wheel
  • Male-Female , Male-Male jumpers
  • Single Wheel Light Duty Swivel Plate
  • Nuts and Bolts Assortment Kit
  • Electrical Cable Connectors CH2
  • 1 * 2m – 20 AWG single core wire

First of all, you will need to create a car chassis to mount all the components. You can build the chassis from scratch, or you can purchase a ready-made kit to create your car. If you have a 3D printer then it’s an ideal opportunity to use it to make a custom chassis.

Next, you will need to connect the swivel wheel, along with the L298n on it using nuts and bolts. For the DC motors, you’ll need to solder wires to their respective terminals and affix them in place using a hot glue gun. Once secured, run these wires through the hole so they can be connected with the motor driver.

It makes no difference how we pair the wires to the terminals; if necessary, we can swap them when connecting it to the L298N or alter them in our code as our programming grants us control over both its speed and revolution.

Next, you will need to connect everything up. We start with L298n to the Raspberry Pi connection. The ENB cable needs to be connected to the ground and GPIO 2 pin of the Pi. The IN1 and IN2 will go into GPIO pins 7 & 6 (Pin numbering used is BOARD). IN 3 and IN 4 will go into GPIO pins 4 & 3. The ENA pin should be connected to GPIO 8 and 5V should be connected to VSYS.

As for the HC-05 Bluetooth module, the VCC and GND pins should be connected to the VSYS and Ground on the GPIO pins of Pi. The RXD pin of HC-05 is connected to GPIO 0 on the Raspberry Pi and the TXD pin of HC-05 is connected to GPIO 1 on Raspberry Pi.

Now it’s time to install MicroPython on the Raspberry Pi Pico. MicroPython is a Python interpreter that runs on many platforms, including the Raspberry Pi Pico. One of the ways you can install it is by using Thonny, a Python IDE for Raspberry Pi Pico. Once you have it installed, open Thonny and create a new file for your code.

Finally, code your Raspberry Pi! You can use the following code as an example and customize it as you’d like.

from machine import Pin,PWM,UART #importing PIN and PWM
import time #importing time

#Defining UART channel and Baud Rate
uart= UART(0,9600)

#OUT1 and OUT2
In1=Pin(6,Pin.OUT) #IN1`
In2=Pin(7,Pin.OUT) #IN2

#OUT3 and OUT4
In3=Pin(4,Pin.OUT) #IN3
In4=Pin(3,Pin.OUT) #IN4

# Defining frequency for enable pins

# Setting maximum duty cycle for maximum speed (0 to 65025)

# Left
def turn_left():

# Right
def turn_right():

# Backward
def move_backward():

# Forward
def move_forward():

# Stop
def stop():

while True:
if uart.any(): #Checking if data available
data=uart.read() #Getting data
data=str(data) #Converting bytes to str type
if(‘forward’ in data):
move_forward() #Forward
elif(‘backward’ in data):
move_backward() #Backward
elif(‘right’ in data):
turn_right() #Turn Right
elif(‘left’ in data):
turn_left() #Turn Left
elif(‘stop’ in data):
stop() #Stop
elif(‘E’ in data):
set_speed = float(speed[1])/100 * 65025
EN_A.duty_u16(int(set_speed)) #Setting Duty Cycle
EN_B.duty_u16(int(set_speed)) #Setting Duty Cycle
stop() #Stop

This code will take inputs from the Bluetooth device and then using the GPIO pins of Raspberry Pi Pico, it will control the motors. To test it out, open a Serial Monitor on your computer and connect to your HC-05 Bluetooth module. Now send commands like “forward”, “backward” etc. You should see that the car moves in its respective direction!

Raspberry Pi Based Parking Assist System

Another interesting project that can be done using a Raspberry Pi is a parking assist system. This project involves setting up a camera, connected to a Raspberry Pi and configured with software that can detect when a car is entering or leaving the area. Once detected, the Raspberry Pi can send you instructions on how to park your car perfectly!

You will need the following things to get started:

  • Raspberry Pi Zero W (we will call this ‘rpi’ or ‘pi’ in this article)
  • 4GB or larger micro SD card for the pi OS
  • Two tinyLiDAR Time of Flight distance sensor modules
  • 32×32 RGB LED Panel
  • 25 feet of CAT5 cable
  • Approx 22 colored male to male header pin jumper wires
  • 5v 2Amp microUSB power supply (cell phone charger)

First, set up your Raspberry Pi according to the instructions provided by the manufacturer. Then download the Raspbian Lite image to your microSD card, and boot up the Raspberry Pi. You can use Etcher for this step. Now set your Pi in a way it’d run headless over WiFi with a static IP address.

You can learn how to do this by visiting the Raspberry Pi Documentation page.

Upon completion of the Etcher writing process, two drives will appear – ‘boot’ and ‘rootfs’. As illustrated in the example above. Boot drive is the one important here. Create a file named “wpa_supplicant.conf.” in the boot drive and this will enable ssh access to your Pi without connecting it to a monitor.

To get started, simply click the ‘boot’ option on the left side of your screen and then right-click anywhere in the white background to select ‘Open in Terminal’. Now enter the following code:

sudo nano wpa_supplicant.conf

Once in the editor, enter the credentials for your wi-fi connection.

country = US
ctrl_interface = DIR = /var/run / wpa_supplicant GROUP = netdev
update_config = 1

network = {
ssid = “WiFi_SSID”
scan_ssid = 1
psk = “WiFi_Password”
key_mgmt = WPA – PSK

The next crucial step is to create an empty file, named ssh. To make this happen, simply type the following command into your terminal window and watch it come alive!

touch ssh

To ensure that we can always find our pi, let’s give it a static IP address. To do this, type the following commands into your terminal:

sudo nano /etc/dhcpcd.conf

Let’s open the nano text editor and add this new text to the bottom of our document!

interface wlan0
static ip_address=
static routers=
static domain_name_servers=

Eject your SD card, insert it into your Raspberry Pi and power up the board. And at this stage you also need to plug the microUSB power adapter into the power port. If all is progressing according to plan, you’ll observe the green LED blinking as if it’s trying to access a hard drive. After that, your WiFi connection should be established but to be double sure, ping it using the IP address you gave it in the ‘dhcpcd.conf’ file.

Now that we have connectivity to the pi, we want to send it commands via installing PuTTY. PuTTY which will allow us to establish an encrypted connection to the Raspberry Pi. After installing PuTTY, you should enter your device’s static IP address in the ‘Host Name (or IP address)’ field. You can then open the connection by clicking ‘Open’ at the bottom of the window. PuTTY will ask for a username and password – type pi for both and hit Enter.

Once logged into our Raspberry Pi, we’ll want to update it with all of its latest packages. To do this, simply enter `sudo apt-get update` into your terminal window – this should take about 5 minutes. When complete, run `sudo apt-get upgrade`. This will take a bit longer, approximately 10 minutes. Once that is finished, it’s time to get a graphical FTP file manager called WinSCP.

Set-up the Raspberry Pi with WinSCP and log in using the same credentials used for PuTTY. You’ll now be able to transfer files directly from your computer to the Raspberry Pi easily. Finally, install any libraries or applications you need for your project onto the Raspberry Pi. You will also need to acquire the necessary driver files from both WinSCP and PuTTY. If you’re confused about this, check out the official documentation or online guides.

Now it’s time to wire it all up. To power the LED panel, we used the same adaptor to provide energy for both it and the Pi. To do this, you must cut into those thick red and black wires then plug them into pins 2 and 9 of that 40pin Pi connector. After doing so your setup is complete!

To better reach our side tinyLiDAR sensor, we modified a 25 foot CAT5 ethernet cable by connecting the pi header pins on one end and the GROVE connector pins to the other.

To properly fire up your device, begin by plugging the microUSB charger into the pi and wait for the tinyLiDAR sensors’ blue LEDs to blink quickly – an indication that they are correctly collecting data. This ensures that you have written a successful code.

With care, connect pin 2 for powering the LED panel. Be mindful not to cause a glitch while doing this! If you spot any bright LEDs that are frozen on your LED panel, it’s likely due to a malfunction so make sure to unplug its microUSB power from the pi and wait several seconds before attempting the power up sequence again.

Now it’s time to code! The example code can be found online and copied onto the Pi. To run this, you’ll need to ensure that all libraries are installed.

Congratulations! You have just successfully completed your very own Raspberry Pi-enabled car project. Enjoy your newfound knowledge as you continue to explore even more exciting projects with your awesome new skillset! [2], [3]
