Interior Vehical Controlls with BS2
Archiver
Posts: 46,084
I'm not really new to the Basic Stamp scene, but I am definately no
expert. I am redoing the electrical systems on my 1990 Jeep
Wrangler and I would like to integrate a BS2. I know how to monitor
the resistance from my fuel gauge to create a "low-fuel" light as
well as some other basic operations, however I do not know the best
way get a 12V output from the basic stamp. I have read about Solid
State Relays and I remember in my grade 11 Electronics class when we
built a night light using a photoresistor and a tranistor to turn
on a 120V light.
I would like to know how to get a 12V output to control things like
Stereo Amplifier/Fan Turn-on, Power Door locks, Dome light, and
other basic 12V vehicle systems. Should I use relays or
transistors? And what kind would I use?

to the circuit, the stamp driving a transistor to drive a relay is a valid
option.
To turn something on by supplying a ground (device already has +12 volts and
needs to be grounded to turn on) a transistor driven by the stamp is good.
This would do well for low current applications (2n2222 for 300 mA or so).
For higher current applications (and supply ground to turn it on) a logic
level MOSFET such as an IRL 520 will suffice.
These ideas are only one of many different ways to accomplish the same end
result.

This really depends on how much current your 12-volt circuit requires.
