This code demonstrates how to drive HO-scale train signals. LEDs are wired to the Arduino with a resistor. The program applies a "lamp" effect on any LED using digital output in co-working mode. Based ...

Whereas a typical scale would then simply show the resulting number on an LCD display, [Mirko] decided to use a moving coil meter driven by the Arduino’s analog output.

This paper presents an application that using Arduino and Bluetooth electronic scale to connect to smart phones to obtain weight information of daily water intake. Bluetooth technology is low-power, ...
