Beginning Embedded Electronics - Power Supply Kit From Sparkfun
I remembered that I was sweating for weeks about what should I have for a power supply circuit. However, I came accross this and all of my worries vanished. Everything you need to power your microcontroller project is all in here! The breadboard, the voltage regulator, the capacitors, the wires and more. It even comes with a 9V Wall Wart, and Barrel jack to recieve power from an electrical socket. The best part is that this kit can be altered. You don't want the yellow LED? Simply remove the item from your kit in the checkout screen. I had to do this for the wall wart and the barrel jack. I decided to use a simple 9V battery for my microcontroller project.I definitly recommend this kit if you're starting your first microcontroller project for the first time like me.
