Can anyone please help me out here.
I'm building a device that will switch the rear indicating lights of a car while it's decelerating.
I'm using a 4093 and it runs of 12v from the car, obviously. The problem is that even when I merely touch the supply lines on the breadboard the unit starts oscillating. it's not supposed to, it's merely a logic circuit working from either a positive or a negative. And no inputs or outputs of the 4093 is left floating. Even while I'm typing now it "flashes" every now and then, without touching or doing anything. It's probably a fault or poor design somewhere in the circuit.
Without going to in depth with how the circuit works, what can cause this? Any ideas or tips on using cmos?
