W wannaBinventor Member Apr 7, 2011 #9 Go ahead and explain what your other input and outputs are like and we will go from there.

Click to expand... i have 2 pin in 16f676 which are pin no...2 ---RA5/T1CKI/OSC1/CLKIN & pin no...4 ---RA3/MCLR/VPP. i have requirements 2 i\p, & 1 o\p.... (1)_ mains on & (2)_ inverter on and (3)_for relay drive.. pin no...4 is only for i\p .so , how can i use it ?

Mike - K8LH Well-Known Member Apr 16, 2011 #13 That schematic would suggest you have more than 1 pin available so what's the problem, again?
