Count down timer for UV lamps using PIC16F887
Here is a countdown timer for UV exposure lamps @ cuteminds.com Here follows a simple count down timer useful for the production of pcbs using photoresist and UV lamps. We have used a pic 16F887 Microchip microcontroller; there are no particular reasons, we have simply used the...
