Arduino board requires a USB cable connected to a laptop/PC or an external AC/DC adaptor for power supply. If you want a portable Arduino based project, you need a battery for power supply. 9V PP3 is ...

You can also go the 9v battery route plugged into the on-board regulator of the Arduino but the low mAh rating of a 9v won’t allow your project to stay running for very long.

Let’s see what kind of components we need for this circuit. 1. Arduino UNO or any Arduino board 2. Breadboard where we will connect the components 3. Cables for the connection between the components ...

Johan Kanflo has been using Arduino compatible boards based on Tiny328 MCU with an ISM radio module (wireless Arduino clone), but he found that finding a case was not easy, and was quite not ready to ...

Arduino Program for Battery Voltage Monitoring: The complete Arduino code and Demonstration Video is given at the end of this article. Here we have explained some important parts of the code. Here, we ...

My idea was really simple: I would make a circuit that would fully discharge each of the batteries while measuring how much energy it produced (displayed in Joules and in Watt-Hours). The circuit ...
