Hello everyone,

I am using a 16F84 to activate a motor that runs off of 5Vdc or 12Vac
and pulls about 1A.  I am using a 12Vac / 200mA wall transformer for the
power supply, rectifiying it, and then regulating it at 5V for the PIC.
(I choose the 200mA supply because of the PIC maximum sinking currents)
If I use the 12Vac to activate the motor will it still affect the PIC
even though the power supply would have gone through rectifying and
regulating before it got to the PIC?

Could I use the 5Vdc instead and just put a diode across the relay I'm
using to trigger the motor to prevent kickback or would that affect the
PIC?

My last question is that if the motor requires 1.0A and the wall
transformer supplies 200mA, will it turn on the motor?

I would appreciate any help.  Thanks in advance.
