Hello everyone, could someone help me with a simple circuit I need to implement in order to add a function in my car. What I need to do it very simple but I am struggling to find out which component/IC could solve it.
Once I press a button in the dashboard of my car, I need to activate or deactivate a transistor, to turn ON/OFF another circuit.
After opening the dashboard of my car, I found the following circuit attached in this thread.
How the circuit works:
Pin 8 has constanlty 5 volts and if I press the "force sensitive resistor" it sends a pulse of 40mA to somewhere and it does something. (the full PCB is basically 3 times the same circuit. Lock/unlock doors, hazard lights, and one third button that is not being used and I will add a function - OBD system)
Pin 17 - it has 12 Volts only when the button is "ON", as I already tested the whole circuit to check what is going on, after pressing the button, other circuit in the car sends 12V to the pin 17 to indicate the switch is ON.
My question: which IC / circuit / component, could give me a logic state "zero" or "one" once a pulse is sent or perceived? It has to be: I press once, and a transistor is activated, I press again, and it switches it off.
Kind Regards,
Guilherme Monteiro
