Battery Level - ADS1015 or Arduino

[amee]

Hi All,

Please help to clarify -

Do i need an ADS 1015 if i'm using Arduino Pro Micro for my button Controls and have an Serial output from Arduino ( with connection from battery to arduino analog in) ?

The atmega32u4 chip on the Pro Micro already has the built-in 10-bit ADC so you don't need an ADS1015 for battery monitoring.

Can you please show me, how it´s working? Do I need a special arduino code or is it work "out of the box"?

You need of course a battery monitor code on both the arduino chip and on the Raspberry Pi side.

Here's a sample code from the Arduino IDE:

Code: Select all

/*
  ReadAnalogVoltage

  Reads an analog input on pin 0, converts it to voltage, and prints the result to the Serial Monitor.
  Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
  Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

  This example code is in the public domain.

*/

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A0);
  // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
  float voltage = sensorValue * (5.0 / 1023.0);
  // print out the value you read:
  Serial.println(voltage);
}

Oh great. thank you. I want to use the mintybatterymonitor. So the battery is connected to GND and RAW on the arduino mirco board. Where has to wire SLC and SDA coming from the PI?

i believe the minty script is tailored to use the ads. if you want to use the onboard atmega one, i think you want to use hoolyhoo's gbzbatterymonitor instead. you should not need to connect the slc and sda as that is handled in the board (i think anyway - i haven't tried this on the tinkerboy board, but i've used another board with the built-in atmega controller as the monitor, and did not need to connect gpios for it to work)
