Hi, im new with IC project and a need some help
I`m trying to make a circuit that mounts in the car and can activate a solenoid if remote button is pushed twice in short sequence.
The car has a negative -12v signal as a push the "open" button, the ideea is that at the first push a relay is opened and kept open by the frist 555 IC and at the second push the second 555 timer active the solenoid to open the trunk. I want to stick to OEM keyfob, trying to avoid multiple remote controls.
i made a circuit using 555 timer IC in falstad but i have some problems:
- can 555 timer switch the 12v needed for the solenoid?
- in the simulation i see a spike at the first push of the button, can it happen in real life?
- what kind of signal is needed for solenoid activation?

If anyone have a simpler solution im happy to hear it
