Recently, many cars are equipped with Remote Car Door Controller called Keyless entry. On this page, I will introduce the equipment which changed a remote control for the engine start into the door lock. The equipment which I used is REMOTE STARTER MODEL RS82I which is made by BULLDOG SECURITY Inc. in U.S.A. The original use is the equipment to start an engine from the car outside when cold, and so on. If you want to buy the door lock controller newly, it's better to buy the KEYLESS ENTRY.
The purpose of this page is to introduce the circuit which makes the pulse signal using the rising edge or falling edge of the input signal.
