I’ve read through a lot of tutorials online to make an Arduino Clone on a breadboard, and some of them are great, but none of them really seem to have it all, so I’m going to attempt to bring it all together here and provide a tutorial with schematics, breadboard photos, Bill of Materials, and descriptions of all the materials.
I’m going to provide the schematic for the system I am building here along with breadboard photos as it is constructed. You can also refer to the Standalone Arduino Tutorial on their website for breadboard photos and more explanations. (http://arduino.cc/en/Main/Standalone)
Before you attempt to make your own, buy one. Its much easier to troubleshoot this when you know how it works and whats going on. If you buy one or even just borrow one and have a chance to play with it, load some programs, test it all out, it will be a lot easier to troubleshoot what is wrong when you start building it.
Step 1: What's Needed
The following is a list of all materials needed for this tutorial. The next step will go into more depth of each component, what’s necessary, and what can be changed.
***NOTE*** : BOM stands for Bill Of Materials. This is simply a detailed list of each item that is needed, the quantity, price, etc to catalog all the necessary information.
Components (included in BOM):
1. 1 x LM1117T-3.3/NOPB Voltage Regulator (3.3V)
2. 1 x LM7805CT Voltage Regulator (5V)
3. 1 x LED RED
4. 1 x LED GREEN
5. 2 x 220 Ohm resistor
6. 1 x 10k Ohm resistor
7. 4 x 10 uF capacitor
8. 2 x 22 pF capacitor
9. 1 x 16 MHz clock crystal
10. 1 x Atmel ATmega328P-PU AVR microcontroller WITH ARDUINO BOOTLOADER
11. 1 x 28 Contact DIP Socket
12. 1 x 9 Volt Battery Connector
13. 1 x 9 Volt Battery
Also needed (not included in BOM):
14. 22 AWG wire
15. 5 Pin Header
16. 1 x small momentary normally open ("off") button
17. 1 x FTDI FT232 USB Breakout board
18. Breadboard (prototyping board)
