Hope someone can help - I have a headache!
I've been trying to prototype this circuit on breadboard when suddenly a friend brings to my attention a flaw. The circuit itself is to fold wing mirrors in on a car when the car is locked, and to unlock them when it is unlocked.
It is possible for both relays to be energised at the same time due to the capacitors keeping the circuit live for a few seconds. This is undesirable.
Neither of us can work out how to prevent this from occuring.
Circuit is below - note the two wires on the left are the lock motor wires. On locking one is +, one is - When unlocking polarity is reversed.
Any help is greatly appreciated.
