Embedded Programming

1. Browsed and Documented Information from Microcontroller's Datasheet

The below picture shows the pin configurations , memory capacity, supported communication protocols, and power requirements.

2. Programming the ESP32 with Ardunio IDE

First import the esp32 boards into ardunio IDE by following the steps below.

3. Wiring the Hardware

The 12 th , 14 th and GND pins are used for this programming to blink and toggle the red and green led's.The Cathode of the both led's are soldered to the board and connected to the GND of the ESP32 and the pins 12 and 14 are connected to the red and green led.And program is uploaded as shown in the figure.

Blink

Toggle

4.Source Code for Blink


void setup() {
  pinMode(12, OUTPUT); // Set pin 12 as output
  pinMode(14, OUTPUT); // Set pin 14 as output
}

void loop() {
  digitalWrite(12, !digitalRead(12)); // Toggle LED on pin 12
  digitalWrite(14, !digitalRead(14)); // Toggle LED on pin 14
  delay(1000); // Wait for 1 second
}

4.Source Code for Toggle


void setup() {
  pinMode(12, OUTPUT); // Set pin 12 as output
  pinMode(14, OUTPUT); // Set pin 14 as output

  digitalWrite(12, HIGH); // Start with LED on pin 12 ON
  digitalWrite(14, LOW);  // Start with LED on pin 14 OFF
}

void loop() {
  digitalWrite(12, !digitalRead(12)); // Toggle LED on pin 12
  digitalWrite(14, !digitalRead(14)); // Toggle LED on pin 14
  delay(1000); // Wait for 1 second
