I am using a circuit in my car that include some CMOS logic gates and 555 timers.
I know this chips work OK within 3 to 15 Volts.
The projects work perfectly in my bench with a 12 volt battery BUT when I conect it with the battery from the car it work ok until I actvate a switch in the car like the door lock.
Its look like my project is getting some type of spike or glitch from the car electrical circuit.
What I have to do in order to fix this??? Do I have to install some kind of debounce circuit???
Do I have to install a Voltage Regulator???
Can somebody give me detailed instrucctions or point me to a wep page were I can find more info about this or a circuit that I can copy.
Thank you for your time and help.
