Topic: Engine random speed + wifi control

I built my platform to show at school, it runs an engine and lights a led RGB randomly. The display shows the RPM speed and the temperature of the 2N2222 trasistor with a Dallas temperature sensor.
To detect rounds i use an encoder with a laserbeam and a photoresistor. When i connect to the NODEMCU, i control the engine speed, the RGB led and i read the tempereature and the spin rate too.

Very neatly packaged. Nice Work!
