This repository contains MCU firmware for a device which can be used to switch between multiple audio inputs and control volume using an IR remote controller.
The project electronics are custom designed and include, among other things:
- A PIC16F15344 microcontroller
- Analog MUX circuitry for input selection
- A motor controller potentiometer for volume control
- MOSFET H-bridge motor driver for controlling the potentiometer
- An IR receiver for remote control
