We did the microcontroller comparison virtually where we met until very late, but we learned a lot about their differences, learned to know more programming and electronics terms. Finally, here is a picture of us when we finished the group work, all very tired but with strength to continue with FAB ACADEMY.
LINK TO THE PDF FILELED programming is done through the Blink from the Arduino.
With the motion sensor in our inventory, we will try to connect the XIAIO to achieve its operation.
The distance sensor is connected to the board to determine its operation.
To start programming our QUENTORRES board, I use the ARDUINO.IDE, from here I start with the programming for the LED's on through the button.
ARDUINO.IDE SOFTWAREFollow the steps in the img
Being in the program we go to FILES/PREFERENCES , here 2 links are added so that the program can download all the relevant information about the XIAO RP2040. Here I leave the 2 links to copy and paste in the ADDITIONAL TABS section. Finally we click OK and it will start downloading all the necessary information.
PACKAGE PRO RP2040 PACKAGE ESP32
Next click on TOOLS / TABLET / TABLET MANAGER , in the tab put the word PICO and install the document called RASPBERRY PI PICO / RP2040.
Finally, we look under TOOLS/TARJETA/RASPBERRY PI PICO/RP2040 and add the SEEED XIAO RP2040 processor. This confirms that the installation is correct and we can start programming.

// define led acording to pin program
int led = 26;
void setup() {
// initialize digital pin led as an output
pinMode(led, OUTPUT);
}
void loop() {
digitalWrite(led, HIGH); // turn the LED on
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off
delay(1000); // wait for a second
}
I USED THIS CODE FROM THE COMMON PROCESSES OF THE ARDUINO, IT COMES BY DEFAULT IN THE PROGRAM.
- I want to BLINK the first LED connected to PIN 26 or D0, so that it only blinks without activation without a pushbutton.
- The programming is divided in 3: DEFINITION, VOID SETUP and VOID LOOP. In the first one you define the PIN, in VOID SETUP, the LED as output and in VOID LOOP, the time and the flashing that the LED will have.
- After programming it, click on VERIFY at the top left and after that, click on UPLOAD where we load the code to the board and automatically you will see the process in action!
BLINK FILE .INO
const int ledPin1 = 26;//first light RP2040 pin 0
const int buttonPin = 27;// button pin RP2040 pin 1
int buttonState = 0;//initial state of the button
int i = 0; //variable intensity led
void setup() { //declaration of inputs and outputs
pinMode(ledPin1, OUTPUT);
pinMode(buttonPin, INPUT);
}
void loop() {
buttonState = digitalRead(buttonPin);// we read the
state of the button if (buttonState == HIGH) { //if we press the button
digitalWrite(ledPin1, HIGH);
delay(500);
digitalWrite(ledPin1, LOW);
delay(500);
digitalWrite(ledPin1, HIGH);
delay(500);
digitalWrite(ledPin1, LOW);
delay(500);
digitalWrite(ledPin1, HIGH);
delay(2000);
digitalWrite(ledPin1, LOW);
delay(1000);
}
else { //if we don't press the button
digitalWrite(ledPin1, LOW);
}
}
THE CODE I GOT IT FROM ADRIAN'S SITE
ADRIAN TORRES PAGEWith the following code you can make the push button programmed with the LED, code is attached.
PRESS BUTTON .INO
// Define the pins to be used
const int trigPin = 2; // Output pin of the ultrasonic sensor
const int echoPin = 3; // Input pin of the ultrasonic sensor
// Define variables to store the times
long duration;
int distance;
void setup() {
// Initialize the pins as input or output
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
// Initialize serial communication
Serial.begin(9600);
}
void loop() {
// Send a 10-microsecond pulse to the output pin
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
// Measure the time it takes for the echo to arrive
duration = pulseIn(echoPin, HIGH);
// Calculate the distance in centimeters
distance = duration * 0.034 / 2;
// Print the distance to the serial console
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" cm");
// Wait a moment before repeating
delay(1000);
}
Here I could help me with Adrian's Page to make the connection of the Quentorres with the sensor, in this way through the DATASHEET and Dupont Jump female/female cable.
ADRIAN TORRES PAGE SENSOR DISTANCE .INO
#define SENSOR_PIN 2 // Cambia este número al pin
al que hayas conectado la salida del sensor
void setup() {
Serial.begin(9600);
pinMode(SENSOR_PIN, INPUT);
}
void loop() {
int motionDetected = digitalRead(SENSOR_PIN);
if (motionDetected == HIGH) {
Serial.println("Movimiento detectado");
} else {
Serial.println("Sin movimiento");
}
delay(1000); // Puedes ajustar el tiempo de espera
según tus necesidades
}
I got help from Adrian Torres but I also made some modifications in the code, to understand it better I asked Chat GPT for help.
ADRIAN TORRES PAGE- Here is the Prompt:
"Hello! Chat GPT give me the code in ARDUINO.IDE to program a RCWL-0516 Motion Direction Distance 5-7m and tell me in which pins I have to connect in the XIAO RP2040."
- Then I question about the pins, here is the prompt:
"Which pins do I connect the sensor to ground, power supply and Out"
- Then I checked the Xiaos's DATA SHEET and the sensor's pins, below this page you can check the steps
SENSOR MOVEMENT .INO
