Instead of upgrading, [fichl] came up with a device that turns his single channel amp into a completely programmable one, with just an Arduino and a handful of servos. The amp in question – an ...

THIS CODE IS OBSOLETE * It needs to be updated to be compatible with changes to the ESP32 standard libraries. Also, if fine granularity control is required, it needs to use long int arithmetic instead ...

Also due to timer1 being used PWM on pins 9 and 10 won't work (3, 5, 6 and 11 are still fine though) Servo motors are easy to use and require minimal hardware. You simply connect the power lines and a ...

The servos are all controlled by an Arduino Uno fitted with an Arduino Sensor Shield. Everything is fitted together with a 3D printed chassis and limb segments that bolt directly on to the servo ...

This DIY solar tracker project mimics this behavior using three simple main components: An Arduino UNO board, a servo motor (with a sunflower paper decoration attached), and two photoresistors ...

The Arduino then interprets this into data that a servo can use to move into position, aligning with the game's location in real time. If you want to look at this project in action, head over to X ...
