Master The Basics Of Arduino | Learn Arduino Step by Step

Install the Arduino IDE on Windows 10, and upload your first sketch via USB. Verify code, manage boards and libraries, and learn about bootloader options.

Set up a circuit on a breadboard for Arduino Uno, wiring power, ground, and an LED with a resistor to limit current, and program a blink on a digital pin.

Master the Arduino basics by learning setup runs once and loop runs forever, digital write for high/low LEDs, and basic C/C++ syntax, including pin modes, simple functions, and LED blinking.

Learn to read data from the Arduino serial monitor by printing strings to the terminal, adjusting baud rate, and debugging with serial output to display LED states and program data.

Learn how to use strings with Arduino, implement for and while loops, use continue and break, initialize and update variables, and concatenate strings to drive LED blink patterns.

Explore digital input with a push button in Arduino, using pull-up and pull-down resistors, external or internal, and wire the button to observe led blinking on press and release.

Learn how to read a potentiometer with an Arduino and a 10-bit ADC, using a voltage divider to convert 0–5 V to 0–1023 and driving an LED by thresholds.

Read analog signals from a photo sensitive sensor, gas sensor, and microphone sensor with an Arduino, wiring A0, 5V, and GND, and use thresholds to drive an LED.

Learn how to output analog PWM signals to control a DC motor speed using a transistor amplifier, with Arduino analogWrite values from 0 to 255 and a 0–5 V range.

Learn to display text on a 16x2 LCD, using an I2C module or direct connection, wire RS/E/D4-D7, install the LiquidCrystal library, find the I2C address, and create scrolling text.

Learn to control a servo motor with Arduino using pwm signals on pin 9, converting potentiometer input to 0–180 degree positions with 20 ms timing.

Connect a PS/2 keyboard to an Arduino, wire data and clock lines, and read keystrokes with a PS/2 library and interrupts. Learn about scan codes and testing keys.

Connect a 4×4 keypad to an Arduino and scan its row and column pins. Use the keypad library to read pressed keys and print results to the serial monitor.

Connect the RC522 RFID module to an Arduino Uno, install the RFID library, read a tag’s serial number and its 16-byte data blocks, then upload and test with a scan.

Learn to use the hc-sr04 ultrasonic distance sensor with arduino by wiring trigger and echo, sending a pulse, and calculating distance from time in microseconds using speed of sound.

Master the basics of Arduino by wiring a SIM900 GSM module to Arduino, selecting antennas, and using Software Serial and AT commands to send SMS and place calls.

Learn how to set up the HC-05 bluetooth module, enter program mode, configure name and password, adjust baud rate, and test connections with a bluetooth terminal and a mobile phone.

Learn how to set up FreeRTOS on Arduino, a free real-time operating system for embedded devices. Install the library via GitHub or library manager, verify, and create tasks and delays.

Set up the FreeRTOS library on Arduino, create and manage timed tasks with delays, and compare concurrent execution and priority effects against running without FreeRTOS.

Discover a more accurate delay method for Arduino and how to manage tasks with delete, suspend, and resume functions in Free Auntie OS.

Learn how mutex acts as a gate keeper to ensure only one task accesses a shared variable at a time, preventing data races and volatile issues in concurrency.
