Explanation of How to Make Battery Level Indicator DIY using LM324 IC

The process of making a battery level indicator using LM324 IC is quite simple. The following steps will help you build one for your device:

Step 1: Gather components

To get started, you need to gather the all the components provided above in the list of components section. The next step involves soldering the components to the PCB or vero board exactly as shown in the circuit layout provided above.

Step 2: Connect wires

Now connect the wires to the battery connector and the PCB board. Make sure that the wires are connected correctly as per the circuit diagram. Connect one wire from the battery connector to the positive side of the board and the other wire to the negative side.

Step 3: Testing

Once the work on the board is completed, connect the battery to the connector, and the LEDs will show the battery level. If all four LEDs are glowing, it means the battery is full. If only three or two are glowing, it means the battery is running low, and if only one is glowing, it means the battery is almost dead.

Conclusion of Battery Level Indicator DIY

Building a battery level indicator diy using LM324 IC is an easy and efficient way to keep an eye on the battery level of your devices. The process involves gathering a few inexpensive components and soldering them to a PCB board. The end product is an accurate and efficient battery level indicator that’s affordable and easy to build. So the next time you’re looking to build a battery level indicator, remember to use an LM324 IC, and you’ll have a fully functional battery level indicator in no time.
