In updateBatteryLevel() function, we read analog A0 and then update Battery level by calling setValue().

void updateBatteryLevel() { int battery = analogRead(A0); int batteryLevel = map(battery, 0, 1023, 0, 100); if (batteryLevel != oldBatteryLevel) { // if the battery level has changed Serial.print("Battery Level % is now: "); // print it Serial.println(batteryLevel); batteryLevelChar.setValue(batteryLevel); // and update the battery level characteristic oldBatteryLevel = batteryLevel; // save the level for next comparison } }
