ATmega328 powers open source WatchDuino

Watch-a got on your wrist?

The WatchDuino is an open source project that combines inexpensive electronic parts with complex Arduino (C++) code.

Key project components include Atmel’s versatile ATmega328 microcontroller (MCU), a crystal oscillator, LiPo battery and Nokia’s 5110 LCD screen.

“WatchDuino is not only programmable, it’s fully hackable from hardware to software. You can build your own out of [inexpensive] components [available] at a local electronics store,” a WatchDuino rep explained.

“[Plus], you have the full source code of the watch’s operative system at your disposal. The ability to build the whole thing from scratch and being able to hack at every level of it will greatly appeal to electronics hobbyists and Makers.”

Currently, primary WatchDuino features include:

• 

Time and date (analog and digital output)
• Alarm / countdown (with custom music)
• Games (Pong & Snake)
• Rechargeable battery (via USB) and meter
• Low-battery mode (lasts up to two years with a 240mAh battery)
• Integrated screen light
• Compact design
• Framework-like architecture to easily program custom screens

On the software side, the WatchDuino can be programmed via two methods: hacking the system itself or simply customizing various features and apps.

“Since WatchDuino’s software is open source, you have the full source code at your disposal to make any modifications you like,” the rep added.

The WatchDuino will likely hit Kickstarter at some point in the near future as a fully assembled device. In the meantime, you can check out the project’s official page here.
