Looking good!

I see headers and hook-up wire! What kind of fun and games are those destined for? I ve just started messing with Raspberry Pi s and Arduinos with my 2 boys. Lots of headers and hook-up wire in our future!

Many things practical, and some things not. Here’s one that’s very practical. 2 Arduino Nanos + GPS + OLED + NeoPixels + Piezo + Rotary Encoder. It’s a speed alert device. Here, it’s set to 40mph. If I go 41-45, the neopixels will flash orange and the piezo will buzz. If I go 46 or over, the neopixels will light up the car with a frightful custom animation set that looks like those new LED lights on top of police cars. The rotary encoder allows configuration. This helps me avoid getting carried away in the flow of the other speeding cars.

The Legos were intended to be a temporary solution until parts arrive for a more permanent mount. But I have developed an appreciation for them and won cool-uncle points from my nephews. So this might be closer to the final product than I had anticipated.

You’ll enjoy your Pi and Arduino future. Be sure to print some pinouts and power supply specs for the different types of Arduinos you own. That’ll save you from a good deal of grief.
