Project Hardware Software Selection. Arduino Uno - It is a microcontroller that gives commands to the robot.. Motor driver - It helps to control the motor attached to the robot, it is connected with ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

Arduino Obstacle Avoiding Car Circuit Diagram . The complete circuit diagram for this 2wd obstacle avoiding robot is given below. As you can see, it uses an Ultrasonic sensor to take measurements in ...

This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display information ...
