so tinkercad has circuit designand arduno now, a real arduino is $20, IDE is free, fritzing is free and does all the exact same layout stuff locally, you save your files and keep them forever.

For example, you can write code to drive a virtual NeoPixel 16×16 matrix. There’s even example code to get you started. There are quite a few other choices in the playground including ...

Arduino Scoreboard Code Explanation. After the successful completion of the hardware setup, now it’s time for the programming of Arduino Nano. The stepwise description of the code is given below. Also ...
