The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Students will get an introduction to Arduino microcontrollers, learn how to design a circuit and make a PCB, and get familiar with all the tools they’ll need in order to do the job.

However, having a simulated Arduino with a debugger could come in handy even if you don’t care about the circuit simulations.
