ReTeSen - AVR-based REmote TEmperature SENsor
I started work on a project to build a remote temperature sensor using an ATtiny2313 for the remote unit and an ATmega168 for the base unit. The project goals are:
- learn to work with the UART on the AVRs
- learn to work on intersystem RF communications
- learn to pull sensor data in and work with it
- learn to interface to an LCD (and maybe learn to use a serial in - parallel out shift register to control the 16x2 LCD).
