The core of the watch is an Arduino Mini. To make it good for time telling, a real-time clock module was added. A DHT11 monitors the temperature and humidity.

Power is via the USB connector or a separate feed. Unusually for an Arduino, the on-board regulator (MPM3610AGQV inductor-inclusive dc-dc module) is rated up to 21V. The Uno Min data sheet says 6-20V ...

Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C control, and the module is 3.3 V powered by the Arduino itself. It seems that external pull-up resistors for I2C lines are ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Two years after launching the Curie-powered Arduino 101 maker board, Intel is calling it quits on the hardware. The chipmaker has announced the end-of-life for its Curie Module, which launched in ...
