The Complete Arduino and Electronics Masterclass

Learn how to use a fully transparent Uno case compatible with Arduino boards sharing the same layout, including opening, inserting, and securing the board and accessing input-output pins.

Discover how the holder secures Raspberry Pi, Arduino, and Arduino Mega boards for stable prototyping, with screws and a breadboard area for organized projects.

Build a visual SOS beacon with an Arduino and LED, encoding SOS in Morse code using a custom flash function and a 270 ohm resistor.

Initialize fourteen digital i/o pins as outputs and create a chaser effect by flashing leds in sequence using a flash function with an adjustable duration.

Create a dual chaser in Arduino by running two LEDs in opposite directions, using the same flash function and loop structure, and upload the code to the Arduino board.

Explore seven-segment LED modules, including the seven segments labeled a to g and the decimal point, and compare common cathode and common anode types with their pins.

Connect and power the seven segment common cathode lcd display with a power supply and jumper wires, then test each segment and the decimal point.

Wire and drive an LED bar graph with Arduino, declare and initialize pins as outputs, then implement a flash function and a looping chaser effect with precise timing.

Declare red, green, and blue as integers, map them to pins 2, 1, and 0 on Arduino, configure outputs, and use high and low to display colors, compile and upload.

Discover Arduino Pro Mini specs: 328 chip, 8 or 16 MHz, 3.3/5 V, 14 digital I/O, 6 analog pins, 32 kb flash, 1 kb RAM, and FT232 FTDI breadboard compatibility.

Compare uart and usart by contrasting asynchronous baud-rate transmission with synchronous clocked transfer, noting pre-shared baud rate versus clock-derived data and their impact on range and speed.

Explore the spi protocol, where a master communicates with slaves using separate slave select lines or a daisy chain. See practical applications from sensors and ADCs to LCDs and DACs.

Explore how Arduino uses serial, SPI, and I2C pins, identifying serial pins 0 and 1 and SPI/I2C pins 10–13, with diagrams and practical interface details.

Learn to connect an I2C LCD to an Arduino using the Liquid Crystal I2C library, address 0x27, initialize a 16x2 display, print and scroll text, and display serial input.

Explore max7219 based displays, wiring vcc, ground, and data pins, and learn daisy chaining to drive multiple seven-segment and character displays from a microcontroller such as a Raspberry Pi.
