Using with Arduino Projects:
Here is an example of how to use the Micro Powercore Charger to power an Arduino UNO and control an LED:
// Example: Powering an Arduino UNO with the Micro Powercore Charger
// This code blinks an LED connected to pin 13 of the Arduino UNO.
// Define the LED pin
const int ledPin = 13;
void setup() {
// Set the LED pin as an output
pinMode(ledPin, OUTPUT);
}
void loop() {
// Turn the LED on
digitalWrite(ledPin, HIGH);
delay(1000); // Wait for 1 second
// Turn the LED off
digitalWrite(ledPin, LOW);
delay(1000); // Wait for 1 second
}
