What you need
- 4S Lithium Battery
- Arduino or compatible microcontroller
- Connection cable
- Power Supply
Steps
- Connect the battery monitor board to the power and data pins of the microcontroller.
- Ensure that the power supply voltage is between 12V and 16.8V.
- Configure the microcontroller to read the voltage signals from the board.
- Display the voltage and charge level data on the screen or via serial monitor.
- Verify the proper functioning of the board during battery charging and operation.
- Adjust any configuration parameters according to the datasheet specifications.
- Implement an alarm system to notify when the battery is nearing depletion.
- Document the voltage and charge data for subsequent analysis.
Example code
void setup() {
Serial.begin(9600);
}
void loop() {
int batLevel = analogRead(A0);
float voltage = batLevel * (5.0 / 1023.0) * (verifica sul datasheet);
Serial.println(voltage);
}
Mini project
