In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

The most popular display system widely used in Arduino projects is the liquid crystal display (LCD). LCD displays consists primarily of two sheets of polarized glass plates with a thin layer of liquid ...

How long can you keep an Arduino circuit running on three AA batteries? With careful design, [educ8s] built a temperature sensor that lasts well over a year on a single charge of three 2250 mAH ...

My perennials always died because I watered them too little or too much, or put them somewhere too dark or too hot. Recently I vowed to keep my plants alive, so I turned to Arduino. I'd been looking ...
