Tsukure Mad Labs Battery Monitor

Sometimes we face a common problem when making any project related to battery or power supply - we don’t know about battery is charged or discharged. To test battery there is one common method which is using voltmeter that is available in the Multimeters. But here we have developed this battery monitor circuit to test the battery charging status. In this circuit we can easily test batteries by connecting it with the circuit. Here some LEDs are used for showing battery status.

Let's Get Started!

Below you will find a list of bits to gather before hand, followed by a detailed schematic. Using a breadboard lay out the components and connect them together as shown. Alternatively you can purchase this module from our shop and simply solder the components in the places indicated on the quality assured printed circuit boards provided.


What You Need...


1 9V Black Battery Holder Clip Snap On Connector Cable Battery / Battery Holder
2 LM358P Integrated Circuit (IC)
2 5mm Green (Diffused) LED
1 5mm Red (Diffused) LED
1 5mm Yellow (Diffused) LED
1 10K
