A detailed circuit diagram is provided to help with the hardware setup of the Arduino Battery Backup Monitor. The diagram illustrates how the NodeMCU, ADS1115 Analog-to-Digital Converter, shunt ...

The true measurement of a battery’s capacity is essential for many scenarios. A capacity measurement device can solve the problem of spotting fake batteries as well. Nowadays fake Lithium and NiMH ...

This Arduino based battery discharge monitor aims to provide an estimation of the capacity left in the battery by measuring and plotting its discharges. This Arduino based battery discharge monitor ...

The SDI-12 orange cable (data) is wired to port 7 on the arduino and the blue (data GND) is wired to the ground on the arduino. The battery is wired into the solar charge controller and the ...

The pinout diagrams are simple, but they're easy to read, and especially helpful for beginners. You can print them out full size so you can set your Arduino Uno, ATMega, or ATTiny right on top for ...

You might think that there could be no form factor that has not as yet had an Arduino fitted in to it. This morning a new one came our way. [Johan Kanflo]’s AAduino is an Arduino clone with a… ...

Mad scientist shrinks Arduino to size of an AA battery Haje Jan Kamps 2:30 PM PDT · April 19, 2016 ...

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.

Denis Hennessy recently encountered a problem we've all faced: he needed some AAs for a battery-eating gizmo, and he was overwhelmed by the choices available. Ignoring the shiny packaging and its ...
