How to Make Your Own Homemade Arduino Uno R3

Intro: How to Make Your Own Homemade Arduino Uno R3

Here I am using 5V mobile charger instead of LM7805 (This version uses a 5V regulated power supply). It's simple and save some space on board. You can you LM7805 but after that you have to use a higher voltage supply that's why I'm using 5V constant charger.

Before moving on, check out this image. It's a great resource for learning what each of the pins on your Atmega chip do in relation to the Arduino's functions. This will clarify a lot of confusion behind why you hook up certain pins the way you do. For even more detailed information, take a peek at the datasheet for the Atmega168 (short version) (long version). Here's the sheet for the Atmega328 (short version) (long version)

is it like the real one and if so can I program it. and I think its a great idea

It's work like the original one.. but to program it you have to connect it with the original arduino or ftdi FT232 RL

[diyboi1235]

ok do you have some diys for the arduino

[Tech Works]

I have and I will upload in some days
