Not exactly schematics, but [Duckman] has some Arduino pinout diagrams he made using ASCII-art. These could be useful when pasted into source code as comments, documenting the pinouts for your ...

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 ...

Circuit and working of 12V automatic battery charger The circuit diagram of the Arduino-controlled 12V automatic battery charger is shown in Fig. 1. It is built around Arduino Uno (Board1), adjustable ...

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.

Here is the complete explanation of how to build a Battery Internal Resistance Meter with Arduino and Atmel ATtiny85 IC. This Internal Resistance Meter gives more accuracy than the available ...

Unlike many units, this battery charger continuously charges at maximum current, tapering off only near full battery voltage. In this unit, the full load current of the supply transformer/rectifier ...

This is a collection of Estonian-written Arduino study materials funded by Tiger University program of Information Technology Foundation for Education in Estonia ...

The battery is wired into the solar charge controller and the arduino/HL4 are wired into the output of the solar charge controller. The arduino usb should be plugged in once everything else is wired ...

The schematic diagram shown in Figure 2 illustrates how L298 H-bridge IC can be connected with Arduino to control two DC motors. Two sets of inputs, one for each motor, are provided to control its ...
