I have a circuit to control my doorbell but Voltage on pin is too low

Hi,
Can you post your code please. so we can see how you read your button?

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Not a fritzy image.

We need a schematic with labels on components and pins, for example the transistor and has been pointed out before, what is connected to the yellow wires? A press button ? ? ?

What is the 330R resistor for?
If you remove the press button, what voltage do you measure?

Thanks.. Tom.. :slight_smile:
