This article described how to build a different type of clock – using the “lilypad” style of Arduino-compatible board and components designed for use in e-textiles and wearable electronics. The main circular board in the Arduino-type board which contains an ATmega328 microcontroller, some I/O pins, a header for an FTDI-USB converter and a Li-Ion battery charger/connector. As an aside, this package is a good start – as well as the mainboard you receive the FTDI USB converter, five white LEDs, a buzzer, vibration module, RGB LED, a switch, temperature sensor, and light sensor.
