Description
Capacitive kitchen timer logic board
This PCB is part of the capacitive kitchen timer project featured on my blog. It contains the microcontroller that listens for capacitive inputs and then reacts to them. The MAX7219 seven-segment controller makes sure that the MCU can display the current time on the two seven-segment displays.
If you'd like to build this project, make sure to also order the following two PCBs as all three are required for building this project:
Please Note: I uploaded a new revision of the gerber file! Therefore the images don't match the gerber file anymore.
