This project requires experience in configuring and coding atMega chips to run low power (for long battery life).
The prototype this project is based on has been developed and proven with the standard Arduino platform.
I want to take this prototype and progress it to a minimum configuration, that put the chip into lower power (ideally 1uA) while in non processing mode (10 seconds) then wakes to perform 1 second of processing / measurement.
The prototype uses 4 analog inputs (1 x pressure sensor, 3 x 4 position rotary switches), 12 digital I/O as outputs, 2 analog as digital outputs.
When the processor determines an error, an alarm is latched on.
The aim of this project is to move closer to the production version, with long lasting battery capability.
Future projects may include wifi data logging.
More detail will be provided to those interested.
Prior experience with ISP / Fusing is required.
