what is mcu examination
Hi, I have made a schematics for some MCU based board that I will use as an alarm central. Now I would like you to examin and correct if there are any mistakes, especialy for resistors and capacitors values and for power supply and osilator.
Please do examine/correct optocoupler and darlington NPN array connection.
I also want to ask if I need to add a small capacitor between the optocoupler photo diode input and sensor, switch and lock/unlock signal. Both sensors operate under 12V, but the signal output is a short pulse, the same is for lock/unlock signal from central locking module.
