Joe Cell Loading Program for the Arduino

I thought it could be a good idea to load the Joe Cell with a lower voltage than 9V and a good vibration, aka the base frequency of the Schumann Resonance, 7.8 Hz. The Arduino UNO, I got one left in my drawer, is easy to program for this purpose.

ArduinoJoeCellLoadingMeasurement

The program measures the voltage and if it is below 1 volt it starts a loading cycle of 2 minutes with the frequency of 7.8 Hz, else it waits 2 minutes.

You need 2 small resistors for 2 LEDs, one red and one green.

Feel free to copy the code and to experiment with your own Joe Cell.

int loadPin = 13;
int redPin = 12; // Let's add some light to the show

int minutes = 120000;

  /*
  I assume that a healthy cell has at least a voltage of 1.0 Volt,
  therefore the Arduino will only put voltage on if the measurement results less than 1.0 Volt.
  The loading will be executed with a frequency of 7.8 Hz.
  1000 milliseconds are diveded by 7.8, this results in 128 milliseconds cycles, 64 on and 64 off,
  a square signal, with a amplitude between 3.3 Volt and 5 Volt depending on the model of the Arduino.

  float voltage = sensorValue * (5.0 / 1023.0);

    digitalWrite(greenPin, HIGH);
