This Arduino project controls a servo motor based on distance measured by an HC-SR04 ultrasonic sensor, adjusting to four angles for different proximity ranges. It updates only when significant ...

Troubleshooting Servo doesn't move: Make sure the servos are powered properly and the control wires are connected to the correct pins on the Arduino. Power supply issue: If using an external power ...

Remember to use separate battery supplies for the Arduino and the two servos. You can use a standard 9V battery for powering the Arduino board through its DC IN port. For servos, a 6VDC supply from a ...

I have a standard servo that can rotate approximately 180 degrees (90° in each direction) and is controlled using the included Arduino’s Servo Library. The code is simple too and I’ll try to explain ...
