Touch button universal remote control

Based on the STC8G1K17 microcontroller and 12 touch buttons, it can learn and store the remote control codes of various infrared remote controls to achieve universal remote control.
Capacitive touch buttons are implemented using ADC.
Long press the setting button (gear) to enter the learning state, the indicator light is always on, lightly touch the button to be learned, the indicator light flashes, point the original remote control to the receiver to transmit the remote control code, the learning success indicator light is always on. If the indicator light is always on, you can continue to learn other keys. Exit the learning state if there is no operation for more than a few seconds. After learning is completed, lightly touching the button will transmit the learned remote control code.
