Hands-On Arduino

Learn to wire a push button to an Arduino in Tinkercad, using a pull-up resistor and an active-low input on pin 2 with 5V and ground.

Copy Arduino code into the Tinker Guide simulator and observe how interrupts on pins 2 and 3 adjust the blinking interval from 300 ms to 1,000 ms or 2,000 ms.

Configure serial communication on Arduino and monitor data with the serial monitor. Send a welcome message once per second, ensuring matching baud rates between code and serial monitor.

Explore software serial port programming with Arduino, wiring pushbuttons, resistors and ground, and implement transmitter and receiver roles in a practical, simulated circuit.

Set up the software serial port in an Arduino project, configure a push button, monitor its state, and compile the code to validate the push button-driven transmission.

Learn software serial port programming on Arduino by declaring global variables, waiting for data, validating received values against predefined ones, and compiling and testing the code.

Learn how to read analog signals using the Arduino's inbuilt ADC, connect a potentiometer to an analog channel, digitize the voltage, and print the integer value to the serial monitor.

Learn how to initialize serial communication at 9600 bps, read an analog potentiometer with an Arduino, store the result, and print the integer value to the serial monitor every second.

Configure the Arduino ADC hardware, wiring the three-terminal sensor to 5V and ground, connect its output to the analog input, then upload code and monitor the serial monitor output.

Reuse the existing code to read ADC values from the potentiometer and plot them in real time, reducing the delay to 100 milliseconds for faster graph variations.

Learn to generate pwm signals on Arduino Uno pins 3, 5, 6, 9, and 11 to control brightness and vary signal frequency to power a load via intermediate circuitry.

This lecture demonstrates using pwm on pin 3 to control led brightness through a map function that converts 0–1023 analog readings to a 0–55 brightness range, with real-time scope visualization.

Learn to interface a Bluetooth 5.0 module with an Arduino to control an on-board LED via a mobile app, configuring pins, data and command modes, and a simple receive-and-act algorithm.

Learn to interface a dc motor with an Arduino using a motor driver IC, and master how polarity determines rotation direction while recognizing why direct Arduino drive is insufficient.

Explore wiring a dc motor to an Arduino Uno using the L293D motor driver on a breadboard, powering, grounding, and controlling it to rotate in both directions.

Learn to interface a servo motor with Arduino for precise position control. Set the angle from 0 to 180 degrees using signals and use attach function with a library.

Explore a servo motor control circuit with a motion detector using Arduino, rotating to 90 degrees on motion and returning to 5 degrees when idle.

Master the basics of a 16x2 lcd: wiring, contrast and backlight control, initialization, and displaying text, including language options and formatting up to 16 characters per line.

Learn to interface a 16x2 LCD with an Arduino, use the Arduino library to display string messages, and simulate the circuitry before dumping code on the target.

Engage in hands-on arduino lcd interfacing while tracing unassisted contributions over the past week and forty five days, with seven, six, seven, or eight noted.

Learn to upload code to an Arduino, select the correct board, and verify the welcome message displays on the LCD, demonstrating basic LCD interfacing.
