I am new to electronics and have been messing around with 555 timers and 7 segment display drivers etc etc.
I am currently trying to use an old remote control door bell circuit to set off a monostable timer.
My problem is this:
When activated, the remote circuit only sends out a 0.7v pulse to the sounder circuit.
I would like to 'amplify' this pulse to approx 3v to trigger the 555 timer.
Is this possible? Is this the way I should be looking at this or is there another approach?
Many thanks in advance for any practical advice.
