EEPROM Counter 22

Persist counters and calibration values between resets.

/*
  Roboda verified Arduino sample 0536
  Feature: EEPROM Counter
  Generated for online build, classroom practice, and hardware upload testing.
*/

#include <EEPROM.h>

int address = 21;

void setup() {
  Serial.begin(9600);
  byte count = EEPROM.read(address);
  count++;
  EEPROM.update(address, count);
  Serial.println(count);
}

void loop() {
  delay(1000);
}

How it works

Practice this Arduino feature with a verified Roboda sketch.

1. Read the constants at the top of the sketch.
2. Wire the pins exactly as listed in the pin map.
3. Upload or compile once before changing values.
4. Change one value at a time and watch Serial Monitor or the output device.
