Battery level indicator is a type of indicator which detects the voltages of a battery and shows the condition of battery on seven-segment display or on LED level bar.
I have got a chance to make battery level indicator as my university semester project and I decided to share the procedure on this blog.
Introduction: (How to make battery level indicator ?)
The aim of this project is to make a simple user friendly battery level indicator which provides a linear analog display output and will be configured to display the output on seven segment display.
- Resistors (Fixed Value)
- Variable Resistor
- Zener Diode
LM339N Quad Voltage Comparator
Implementation on Bread Board:
Use IC # LM339, Zener Diode of 5 Volts.
Connect the circuit with 12-Volts DC battery. Adjust the 2-K variable to calibrate the circuit with battery.
The next phase is to implement the circuit on circuit board / soldering. Keep visiting for next update.
In our upcoming post we will discuss the complete process of solar panels installation in Pakistan and how can we power our homes with solar power.
