Project: Build a 5V Converter

If you ever need 5V for your project, but you only have a 12V adapter or 9V battery, the 7805 voltage regulator will be your savior.

This component can provide stable 5V for a microcontroller, and at the same time, it can provide enough power, up to 1.5 A, for the rest of the project like a motor or a bunch of LEDs.

In this project, you’ll learn how to build a simple 5V power supply based on the 7805 voltage regulator.

What You’ll Need

  • 10uF Electrolytic Capacitor
  • 0.1uF Ceramic Capacitor
  • 7805 voltage regulator
  • Perfboard
  • 2 screw terminals
