Arduino for Beginners - (Complete Course From Scratch)

Explore the hardware and software components for this Arduino beginners course: a compact board with 14 digital and analog pins, USB, power jack, 16 MHz crystal, reset button, and ICSP.

Set up the Arduino IDE on your PC, connect the board via USB, upload sketches, and use the serial monitor to display and debug data with Serial.begin, Serial.print, and Serial.println.

Practice converting binary data to hexadecimal and back, learn byte and nibble structure, and use 0x notation to map binary, hexadecimal, and decimal values with a conversion table.

Learn to blink an LED with Arduino by configuring a pin as output and toggling it high and low with one-second delays. The lesson demonstrates both onboard and external LEDs.

Understand the working principle of seven-segment displays, including common cathode and common anode types, with segment pins a–g and the dot, and drive digits 0–9 from a microcontroller.

Interface a seven-segment display with an Arduino by wiring pins as outputs and decoding hex data to print digits 0–9 with a one-second interval.

Explore multiplexing two seven-segment displays with an Arduino, driving each digit via common pins and shared data lines, using hexadecimal codes and timed delays to print digits.

Demonstrates how a 16x2 LCD uses the Hitachi HD44780 controller to print characters by addressing the display and writing data to the data register via RS, RW, and enable.

Interfacing a 16x2 lcd with arduino using the built-in liquid crystal library, wiring rw to ground, using four‑bit mode, initializing the display, printing text, and controlling cursor, blink, and scrolling.

Interfacing a 16x2 LCD with an Arduino in 8-bit mode without an inbuilt library, defining pins, creating print and command functions, and displaying two strings on the two LCD rows.

Learn how to interface a 16x2 LCD with a microcontroller in four-bit mode, covering command and data functions, wiring, and the four-bit data transfer process.

Interface a 16x2 lcd with a development board in four-bit mode without inbuilt libraries, transferring data in two 4-bit steps and printing text on the first and second rows.

Explore how switches interface with a microcontroller using pulldown and pull-up logics, with a 10k resistor example showing input states on button press and release.

Learn to interface a pushbutton with an Arduino, wiring the LED to pin 7 and the button to pin 8 using pulldown resistor logic.

Discover how relays use electromagnetic switches to control 230-volt loads from low-power signals. Understand normally open/closed contacts, coil, and flyback diode protection.

Learn to interface a relay with an Arduino to control 230 V lighting appliances, using digital pins 7 and 8, pull-down logic, and a separate power supply.

Interface an IR proximity sensor with an Arduino by wiring its digital output to a pin, reading it with digitalRead, and driving an indicator while calibrating sensitivity with a potentiometer.

Learn to interface a dc motor with an Arduino using a dual motor driver, powering and wiring grounds and enables, and controlling direction with two push buttons.
