Powering an Arduino has a little magic to it. It wasn’t obvious to me when I first started working with them, but Arduinos have on-board regulation. Taking advantage of this allows for longer power ...

Today we will be designing a Multipurpose Power Supply. The Power Supply will be an Arduino UNO Power Supply Shield which will output multiple voltage range such as 3.3V, 5V and 12V.

Depending on your required output voltage range, it may be possible to power the Arduino from the output voltage it is controlling as proposed in the QC2Control project (note though that feeding 5V to ...

Arduino GPS Tracker Circuit Diagram The Arduino GPS tracker circuit connects three main components: Arduino UNO R3, NEO-6M GPS module, and SIM800L GSM module. This design uses both hardware and ...

How to make an Arduino Voltmeter As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V analog reference voltage) and this range ...

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive… ...
