We started off by downloading Thonny program from the website

We then installed and launched the Thonny software.

After launching it we configured the interpreter, choosing MicroPython (Raspberry Pi Pico) as the launguage that will be used to run the code. And then we installed MicroPython.

Continuation of installing MicroPython

This is where I then brought in picture the Raspberry Pi Pico to use, which is shown in the picture below.

I then began with holding the BOOTSEL button on Pi Pico and then plugged the USB cord to get the options/variants to choose from depending on the Pi Pico I am using. After selecting it I then completed the installation.

We then created a code for blinking an LED the run button to execute the script on the microcontroller.

from machine import Pin, ADC
import time

pot = ADC(Pin(26))
led = Pin(7, Pin.OUT)

while True:
    pot_value = pot.read_u16()
    if pot_value > 32767:
        led.value(1)  # Turn LED on
    else:
        led.value(0)  # Turn LED off
    time.sleep(0.01)
                            

Arduino IDE was downloaded from website and then launched.

We then added the blelow URL into the Additional Library Manager.

http://arduino.esp8266.com/stable/package_esp8266com_index.json

And then installed the Adafruit Library that support the microcontroller (ESP8266) to use.

The micricontroller (WROOM-02) was then connected to the computer.

The microcontroller to be used was then selected on the Arduino Ide software by selecting tool on the main menu, then clicking boards, then selecting the board to use which is the esp wroom02.

#include < ESP8266WiFi.h>

const char* ssid = "UNIPOD Staff";
const char* password = "unipod12345";

const int ledPin = 2;  // GPIO2 is often used for built-in LED

void setup() {
  pinMode(ledPin, OUTPUT);
  Serial.begin(115200);
  delay(10);

  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("Wi-Fi connected.");
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  digitalWrite(ledPin, HIGH);
  delay(500);
  digitalWrite(ledPin, LOW);
  delay(500);
}
                                            

The code was then uploaded and the connection status was printed in the serial monitor.
