Builld a touch activated Valentine’s LED card
Happy Valentine’s from Dangerous Prototypes. This touch activated Valentine’s card is one of Ian’s early projects at DIY Life.
It’s designed to be home-etched on a single-sided PCB. A PIC16F microcontroller fades the LEDs like a heart beat. It’s activated when someone touches the conductive pad, which allows current through a PNP transistor and wakes the PIC from sleep.This entry was posted in DIY and tagged LED card, PIC, Valentine.
