Regular hours
A simple weekend project is an unusual watch. View of the photo:
')
A ready-made board from another project was used. The circuit is extremely simple - the ATMEGA8 microcontroller is connected via I2C bus to the DS1307 real-time clock and the connected microammeters to the 2nd PWM channels via trimmers in 5kom. At the power input is stabilizer 7805.
Source devices:
The scales were redrawn and printed on a laser printer, followed by a sticker over the old ones.
Inspired by the following projects:
www.meterclock.com
www.3meterclock.com
Article of the project: http://licrym.org/ As usual, this is the only repost of articles in runet related to the weakness and instability of the project server.
What else can you do:
By connecting the microcontroller to the com or usb port and writing the appropriate prog, you can make it possible to output not only time, but also processor load, for example, to such analog devices.
