I am trying to find a 12v input and 12v output breadboard power supply but I can't find one. I am making an arduino-controlled lock but the Arduino cannot power the lock strike by itself so I need to use a seperate power supply. The link to make things clearer: http://www.instructables.com/id/Arduino-RFID-Door-Lock/#step0

  • If your input is 12V then why do you need a 12V output? – Ignacio Vazquez-Abrams Jan 22 '15 at 1:12
  • To be a able to use it with a breadboard, I am using a 120vac to 12vdc switching adapter to power the breadboard power supply. – Kyriazis Jan 22 '15 at 1:16
  • What's wrong with just using wires? – Ignacio Vazquez-Abrams Jan 22 '15 at 1:19
  • I want to separate the power from the outlet to positive and ground. – Kyriazis Jan 22 '15 at 1:21
  • ... What is that supposed to mean? – Ignacio Vazquez-Abrams Jan 22 '15 at 1:56

There is nothing special about a "breadboard power adapter" that isn't served by a normal regulated supply. Simply use wires or a barrel jack or some other connector to connect any regulated supply to the breadboard as desired.

They sell 5V/3.3V breadboard supplies on eBay for $3-$5 shipped from China. Buy one and rewire/modify it to bypass the voltage regulator
