MinionCity Arduino Setup
28th December 2012

Yesterday I got the Minion City Arduino compatible device. It's a tiny device that provides Arduino Leonardo compatible board with a built-in RF12B radio. I got two of those to try my hands with Arduino development with the first project planned to be a basic weather sensor (temperature, humidity, barometric pressue, ambient light).

There is scant little documentation, it is all hidden across multiple blog posts and kickstarter project description. The first thing I needed to know was that this is an Arduino Leonardo and then that the LED is on pin 16 rather than the usual pin 13. There is a green led that lights occasionally and I still don't understand it's purpose.

So far I checked the led and the keyboard control which is really nice, now I need to get myself a breadboard and some sensors to do what I really want from it.

Arduino First Play
1st January 2013

With the help of a co-worker who soldered for me the minions and the battery shield and also gave me leds and a switch I could get to play a bit with external parts rather than just the internal leds and radio. So far I managed to control a led on/off as well as experimenting with the analogWrite to light it at different levels and also managed to use the switch to turn the led on and off which was really cool.

Next step is to use the leds and the switch on two different minions and to wirelessly transfer the switch status to control a remote led.

Thanks to my co-worker I got the battery shield fully setup, initially I missed the switch and he managed to solder it to a mostly soldered shield and minion. Initial test seemed to indicate that it doesn't work but that was just me wrongly assuming that the led always lights up at startup, loading a blink sketch on the minion proved that the battery shield works just fine.

Note to self: Need to get loading a version across the radio to work, that would be extra cool and make maintenance of the sensor network a breeze. Will need to make sure that I don't brick the minions across the radio.
