Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty one-channel SMS relay. The device is, in fact, an “isolated electric switch” that can be controlled through the messaging app on your ...

My initial intention was to power the SIM800L module from a 3.7-V Li-ion battery (because it draws a lot of current for proper operation) and power the Arduino Uno from a 9-V alkaline battery. Later, ...

Circuit diagrams and schematics are visual representations of circuits. These images are used to convey information about how to wire a circuit. Often when looking for electronics projects the first ...
