PIC 16F676 Temperature Display

by Edwin Tugano Jr.

for the Olimex sponsored PCB contest

PIC 16F676 Temperature Display using an LM 35 temperature sensor and no less than 70 LEDs driven by a pair of 74ls47's. Watch out for the format of the drill file, the decimal place is not included and the right 3 digits of each coordinate are fractional. The PCB is single sided and uses SMT for the all the chips.
