Hello everyone,

I am trying to use 16F84 to send 22V signal to a system. From experience, 16F84 can only send 5V signal which is below what i need i just need a way to change the voltage to 22V or to any voltage i want thanks.

Thanks in advance

Use a transistor and base via resistor to the pic output

Can you show me a diagram?

I am not that expert with transistor?

Simple diagram in paint will be fine.

thanks in advance
