BTClock - Arduino based clock with bluetooth control
thingiverse
Inspired by the LAMetric display, I have build my own LED display with bluetooth control using a 32x8 LED Matrix and a cheap arduino nano board with bluetooth (Bluething). It also works with other arduino board + additional bluetooth module (e.g. HC05). For manual operations, the clock can be controlled with a rotary wheel. You can choose between the following functions: -clock -timer/countdown -stopwatch -alarm -display custom text (scolling) -options To keep track of the time/date I use a simple DS3231 RTC module . An active buzzer is used to do the alarm. A rotary encoder is used to toggle through the menu and select entries. The 3D printed parts are: Enclosure Wheel LED Grid & shade More details will be published on http://www.dietzm.de
