“Monitoring the voltage level of a 12V Lead Acid Battery (SLA) is easy and simple with this project. The board is made using an ATMEGA328 micro-controller and 12 x 5mm LEDs. The ATMEGA328 microcontroller senses the analog voltage on A3 Analog pin and drives 12 LEDs connected to digital I/O pins of the chip. Input voltage from the battery is dropped using divider resistors. Different colors of LEDs used for easy visualization of battery voltage level. The operating supply of the circuit is 7-15V DC. The battery voltage measuring range is 9.75V to 14.5V. LED Vs voltage level can be changed by modifying the Arduino code.”
