micropython

Sometimes I need a little visual hint to do things, especially when it comes to little things that I should do on repeat, like dayli or even multiple times per day. I’m not really someone who does a lot of sport, but I love to go bouldering. In my “best times” I went three times every week. A few weeks ago I injured my left leg and since then I was not able to go to the bouldering gym anymore.

On a rainy sunday afternoon I found out that the RaspbeeryPi Pico fits perfectly into a 35mm film box if you cut a little hole for the USB port into the lid. Since my box was a semi-transparent white box, I decided to add some LEDs and build a little temperature sensor, that indicates the current temperature range using either a blue, green, orange or red LED. Build I connected the power pin (long side) of each LED to a GPIO port (green = Pin4, blue = Pin5, orange = Pin3, red = Pin2), of course with a 220 ohm resistor in between, and all the short sides to GND.

A few days ago I got two brand new RaspberryPi Pico Boards and so it is time to build something using this new toy. So let’s talk about what it actually is, how to setup a MicroPython development environment and also build a simple example project to make sure everything works as expected. This one is not like the others I won’t go to much into the specs of this board, since you can read them for yourself here, instead I will focus here on two specific things that set’s this Pi appart from others like it.
