I am looking for an inexpensive microcontroler dev board (or similar) that has the following attributes:
1.Can run off standard batteries (AA, AAA, 9V) and doesn't drain a ton of power.
2.Can be programmed in C from a standard Windows PC over USB using free tools.
and 3.Has 4 pins each of which can somehow drive/turn on and off (either directly or via additional circuitry) a set of 4 of these LEDs (not sure if I need to wire them in parallel or series) https://www.jaycar.com.au/red-3mm-led-2800mcd-round-clear/p/ZD0104
