I am using a pic16F84.
I want to send a high signal to the gate of a transistor.
I thought 16F84 send 5V to the gate but when i measured it with a multimeter i found that PortB0 when its high it gives 2V is it strange.
My question is what is the voltage in PORTB0 if no resistor is connect and what is the current that is generated.
Interesting, 4.3V i heard it alot. i am runing my pic at 5V but when i read the voltage its 2V i connect the + of the multimeter on PORTB0 and - on the ground any one know why i read 2V???
It's probably only on half the time. Maybe your code resets after a few instructions or the WDT resets it. Try writing code that sets the pin and then does a long delay.
I am assuming you have nothing connected to the pin.
