Hi. I need some advice with starting this project. I'm fairly new at all this.
I would like to trigger 3 relays with the Teensy 3.1. Could someone recommend relay part numbers for these specs :
contact specs : non-latching 12V DC 100mA
coil specs : Teensy digital output pin
3 different relays needed :
1) momentary spst normally open
2) momentary spst normally closed
3) momentary dpst normally open
Are there relays out there that would be triggered by Teensy 3.1's digital output? So I could just program a digitalWrite high. I also suppose I could substitute two relays for the dpst and just program for both of them to trigger.
Is there also a circuit to do this? I suppose I might need diodes, NPN transistors, and resistors.
Thanks for the help! Let me know what you think and if this is feasible or if I should be going about it in another way.
Hope to hear from you soon.
