Which electronic switch should I use if I want to control 12 V,1A signal with a 5V arduino output signal? [12 V is high powered signal so can't use boosted 12 V output from 5 V Arduino signal - Image is below]
- The switch should work instantaneously [Edit: 10-20 ms max]
- Only Triggering ON is needed. If an option is available through which we can only trigger on and later turn it off in any other way, that option is welcome too
I have tried: - MOSFET but I guess it doesn't work for gate voltage 5V if 12 V signal needs to be passed through. - Triac & Optocoupler - it turns on alright but it's not turning off in any way I know
I will really appreciate the help!
