HI, i m working on my semester project of password proected door lock using 4 bit comparator... when the two inputs or enterted combination and pre-set combination match, the comparator will send a high value of about 2V at its A=B port. i want to drive a relay using this low 2V voltage to trigger high voltage of about 12V. but i dont think so any relay exist that can work on 2V (Vmin = 5V is necessary to drive a relay).
So i need a model number of relay or Solid state relay that can trigger high voltage using low voltage of 1.8 or 2V....
i will be very very thankful if someone help me.....
