Task 59:


Logging code:

#include

int photocellPin = 0;
int photocellReading;

void setup()
{
Serial.begin(9600);
for (int i = 1; i <=144; i++)
{
photocellReading = analogRead(photocellPin);
EEPROM.write(i, photocellReading);
Serial.println(photocellReading);
delay(600000);
}
}
void loop()
{
}


Recalling code:


#include

int EEPROMVal;

void setup()
{
Serial.begin(9600);
for (int i = 1; i <=144; i++)
{
EEPROMVal = EEPROM.read(i);
Serial.println(EEPROMVal);
}
}
void loop()
{
