I have a 555 timer clock output controlling a few things, one of them is the coil of a 24v relay. How can I take the 5v coming from the 555 and pump it up to 24v. ?
What I am doing is using the clock cycle to turn relay on/off . Then the 5v threw the contacts is being counted. Thus if I turn on off the relay 100 times, I should get 100 counts at the counter. The logic works for a 5v relay, but unsure how to change this for a 24v relay.
