Monitoring and Control:
While the EcoFlow Delta 3 Max Plus Back is not directly programmable, it can power Arduino UNO projects. Below is an example of powering an Arduino UNO using the USB-A port:
// Example Arduino code for blinking an LED
// This code assumes the Arduino UNO is powered via the EcoFlow Delta 3 Max Plus Back
const int ledPin = 13; // Pin connected to the built-in LED
void setup() {
pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}
void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
