Light Sensor Photoresistor With Arduino in Tinkercad

Light Sensor (Photoresistor) With Arduino in Tinkercad

Let’s learn how to read a photoresistor, a light-sensitive type of variable resistor, using Arduino’s Analog Input. It’s also called an LDR (light-dependent resistor). So far you’ve already learned to control LEDs with Arduino’s analog output, and to read a potentiometer, which is another type of variable resistor, so we’ll build on those skills in this lesson.

IMPROVED Smart LED Candle Reactive to Sound and Aesthetically Pleasing

*IMPROVED* Smart LED Candle: Reactive to Sound and Aesthetically Pleasing

Remember the “smart” LED candle from a few months ago? Well, the idea was nice, but the overall execution lacked some oomph. Technologically and aesthetically speaking there was a lot to improve. First off, as an artist, I wanted the container for the candle to look amazing. Or at least better than the old cardboard box I
