Monitoring Bitcoins with Atmel’s ATmega328P-PU



A Maker by the name of MiCavaleri has created an inexpensive DIY prototype Bitcoin price ticker powered by Atmel’s ATmega328P-PU microcontroller (MCU).

The tracker – which updates every minute – displays the price of Bitcoins in three different currencies: USD, EUR and GBP.

Aside from Atmel’s ATmega328P-PU (or Arduino Uno), key project components include:

  • 

5x 10k Ohm resistors
  • 220 Ohm resistor
  • 7805 Voltage Regulator 5V
  • 2x 10uF capacitors
  • 2x 22pF capacitors
  • 16 MHz crystal
  • LCD display 16×2
  • 9V battery connector
  • 4 switches (buttons) (I used tact switches)
  • Wire (and quite a lot of it)
  • Plastic box
  • Prototyping board 120x80mm (I used 1½ in total)
  • Adafruit CC3000 breakout board

“I suggest you build everything on a breadboard first using your Arduino. Then you will be able to test if the code works, and that you are able to connect to your WIFI,” MiCavaleri explained in a recent Instructables post.

“These images will show you how to set it up using the CC3000 shield, but it will work with the breakout as well.”
