Arduino UNO Based Obstacle Avoiding Robot Car & RC-Control

Explore the hardware components for the Arduino UNO based obstacle avoiding RC car, including motor driver, ultrasonic sensor, Bluetooth module, push button, potentiometer, breadboard, jumper cables, and four-wheel drive motors.

Download and install the Arduino IDE from the download page for Windows, Linux, or Mac, including driver setup; program with C and C++ and Python to control the Arduino board.

Learn to set up and upload code to the Adreno board using the Arduino IDE, wire the built-in LCD, and implement a simple blink pattern with digital writes and delays.

Learn to blink the built-in led on the Arduino and an external led, using pin 13 then pin 12, configuring pin mode to output, compiling and uploading.

Connect a series of LEDs to an Arduino Uno using a breadboard and jumper wires, then upload code to blink red, green, and white LEDs one after another every second.

control the lcd with an arduino via serial monitor input at 9600 baud, turning the lcd on or off using the characters Y or N on pin 12.

Control LCD brightness with an Arduino Uno by incrementing a brightness value, printing each step to the serial monitor, and cycling from 0 to 255 before repeating.

Learn to dim or brighten an lcd using a potentiometer connected to Arduino's analog input A0, mapping 0–1023 to a brightness range, and uploading the brightness control code.

Learn to control an LED with a push button on an Arduino Uno, wiring the button to a breadboard and using digitalRead to toggle the LCD.

Measure distance with an ultrasonic sensor and indicate safe or danger using a green LCD and red LED, wired to pins 12 and 13 on Arduino Uno, 15 cm threshold.

Explore how ultrasonic sensors measure distance using trigger and echo signals, configure pins, compute distance in centimeters, and display results via serial monitor on an Arduino UNO.

Assemble the Arduino UNO based obstacle avoiding robot car kit by connecting motors and attachments, keeping the protective folio intact during assembly and testing, as shown in a timelapse.

Learn to control one motor with an Arduino and motor shield by installing the motor library, writing speed and direction code, and testing forward and backward rotation.

Connect the remaining three motors to the Arduino motor shield and write code to drive all four motors in unison, then test with forward and backward motions and stop.

program the motor driver to drive forward, backward, and stop, then enable left and right turns by alternating motor pairs, upload the code, and verify rotation.

Refactor the robot control code by creating dedicated move forward, backward, left, right, and stop functions, then call them to drive the Arduino UNO based car.

Explore adding a left and right look to an Arduino UNO obstacle avoiding robot car. Mount ultrasonic sensor on a mechanism and control a motor to scan left and right.
