Arduino Car Projects

Learn to drive a DC motor with the L298N driver on an Arduino car, wiring a single motor and controlling direction with IN1/IN2 and speed with PWM.

Learn to use the infrared receiver and remote with an Arduino car, decode button presses via the infrared remote library, and control LEDs and future drive actions via mapped commands.

Learn to use the HC-SR04 ultrasonic sensor with an Arduino Uno for distance sensing. Wire the trigger and echo pins, power from a digital pin, and read centimeters with pulseIn.

Connect an Arduino to a phone via a Bluetooth 4.0 module and the Arduino Blue app. Create a simple app interface to turn led on and off with buttons.

Configure the ESP-01S WiFi module with AT commands using an Arduino Uno and a blank sketch. Set the module to soft AP and station mode and fix UART to 9600.

Set up a Blink project to control an LCD on the Arduino UNO using the ESP-01S WiFi module, and create your Blink account for project integration.

mount the Arduino Uno on the acrylic chassis with spacers and screws, attach the motors and the universal wheel, and install the l298n motor controller with wiring to the Arduino.

Wire both motors to the motor controller and Arduino, mapping IN1–IN4 to pins 5, 6, 9, and 10, supply 5V and ground to the controller, and prepare for power options.

Test an Arduino car with a joystick powered by a nine-volt battery, validating forward, reverse, left, right, and u-turn movements via a wired remote, with wireless control planned.

Learn wiring for the Arduino car project using pin 12 for infrared receiver output to avoid conflicts with future wifi, with LEDs on pins 7 and 8.

Use an infrared remote to map keypad keys to an Arduino car's movements—forward, backward, left, right, and pivots like forward left and backwards left—controlling two wheels via the motor driver.

Review the Arduino car wiring with a Bluetooth BLE module, TX to digital pins 2 and 3, and add a 47 microfarad capacitor between VCC and ground to prevent brownouts.

Verify hardware connectivity by uploading the blink sketch to the Arduino, connecting the Wi‑Fi module to the Blink platform, and controlling an led via the web dashboard.

Learn to convert joystick deflection into motor speed on an Arduino car by mapping analog reads to pwm, handling resolution differences and forward or backward motion.

Use the ultrasonic distance sensor at the front to detect obstacles within ten centimeters and stop the car, with LED visual indicator and motor control tied to joystick inputs.

Learn to add an audible buzzer to a collision-avoidance Arduino car, comparing passive and active buzzers, testing with an obstacle sensor and LED cue, and integrating noise with motor control.

Compensate for slight differences between two dc motors by applying a software speed offset to the faster wheel to keep an Arduino car driving straight, without extra hardware.
