@futurewiretech1: 12V Battery Level Indicator Using LEDs and Resistors #electronic #diyelectronics #DIY #delectric This video shows how to build a simple 12V battery level indicator using LEDs and resistors only. No microcontrollers or complex ICs required! The LEDs will light up according to the battery voltage, giving you a quick visual indication of the charge level. 🧠 Working Principle: Each LED is activated at a different voltage threshold using carefully selected resistor dividers. As the battery voltage drops, fewer LEDs light up—allowing you to estimate remaining charge from 100% down to 25%. 🔋 Battery Type: 12V LiFePO4 or SLA 💡 LED Indicators: Green = 100% Yellow = 75% Orange = 50% Red = 25% 🛠️ No ICs – just simple resistors and LEDs. 📌 Note: Voltage thresholds can vary depending on battery chemistry. You may need to tweak resistor values for your specific battery type. #BatteryLevelIndicator #12VBatteryMonitor #LEDIndicator #DIYBatteryChecker #BatteryStatusDisplay #SimpleElectronics #ElectronicsProject #LiFePO4Monitor #12VCircuit #LEDVoltageMonitor #LIVEIncentiveProgram #MyLIVEJourney #PaidPartnership
