After last week’s Hello World POF to get started, here is a new Project On Foam:
A battery-powered wireless light sensor node. This is POF 71, and it’s fully documented on the wiki.
It also describes how to keep the node configuration in EEPROM, how to make a sensor node more responsive, and how to get power consumption down for battery use.
The POF includes code examples and uses the easy transmission mechanism, with the final responsive / low-power sketch requiring just a few dozen lines of code, including comments. The sketch compiles to under 5 Kbyte, leaving lots and lots of room to extend it for your own use.
All suggestions welcome. Anyone who wants to participate in these POFs, or in the wiki in general, just send me an email with the user name you’d like to use. I’m only restricting edit access to the wiki to prevent spamming.
