Example Code for Arduino-Blink

Hardware Preparation

• DFR1188 Beetle RP2350 ×1

Function Description

There is an LED on the lower right corner of the Beetle RP2350's main chip, next to which is a silk screen marked "L/25". This LED is used to quickly verify the main control board and code. As shown in the figure:

Sample Code

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);//Set the pin to output mode
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH); //Output high level, light up the LED
  delay(1000);                    // Delay for one second
  digitalWrite(LED_BUILTIN, LOW);  //Output low level, turn off the LED 
  delay(1000);                   //Delay for one second    
}

Result

When the program is uploaded successfully, the on-board LED flashes repeatedly at 1-second intervals.
