In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a ...

This remote switch uses a sg90 servo, an Arduino Uno, and pairs of ATtiny85s with HC-05 Bluetooth modules assembled on protoboards.

– Any Arduino board (I used Arduino UNO) – HC05 Bluetooth module – One SG90 Servo Motor (I got the one with metal gears) – 5x MG996R Servomotors (more powerful than SG90) ...

The build relies on components that are readily available pretty much around the world—SG90 servo motors, ball bearings, and an Arduino running the show.
