Hi guys please deleat if not allowed . I am an auto electrician and looking to make my job a little more easier . we all like an easy life.lol
What I'm looking for is a 2 way circuit simple led circuit for testing key fobs one for testing the remote central locking when you press the button and the other to test to see key the keyfob transponder to see if it talking to the car ring around the ignition barrel to worm out immobiliser issues . I'm looking for a power range to work between 9v and 12v . I would prefer both voltages together if possible .
I live in the United Kingdom so I only have maplin to hand for parts as well as eBay to sauce electronic components . would and one know the circuit diagram if such a circuit can be built
I have a bread board to hand
The old fashion key fobs used to have an ir on them and it was easy to get your phone out of your pocket with a the digital camera to see if it lite up.
Thanks in advance regards james
