Arduino Uno and Visual Displays Bootcamp

Explore the Arduino Uno revision 3 hardware specifications, including the ATmega328P microcontroller, voltage ranges, and bootloader. Review pinout details for digital, analog, PWM pins, plus I2C connections.

Install the Arduino IDE on Windows and Raspberry Pi, configure verbose output for compilation and upload, and learn to write and upload sketches to an Arduino board.

learn to create and upload your first arduino sketch, blink an led on digital pin 13 using setup and loop, via arduino ide on windows and raspberry pi.

Learn the basics of electronics prototyping with breadboards, MB-102 layouts, and bus lines, then power circuits using a three-position jumper and a 9V battery power supply.

Learn diodes and light emitting diodes, including polarity with the longer leg to positive and the shorter leg to negative. Apply V=IR with resistors to limit current and brightness.

Explore a breadboard holder that simplifies prototyping by securely mounting a Raspberry Pi or Arduino Mega 2560 Rev 3 and a breadboard, with included screws and a screwdriver for setup.

Install fritzing, explore its parts library, and build circuit diagrams for Arduino projects, including wiring, rotating components, and saving sketches with the .fzz extension.

Explore Tinkercad's online circuit simulator to build Arduino projects, drag and drop components, wire an LED to ground and pin 13, and run code to blink the LED.

Learn to emit a visual SOS signal with an Arduino Uno and LED by turning a blink into a custom flash function that outputs dot and dash timing.

Wire and power a seven-segment common cathode LED display on a breadboard, connect jumper wires, and test each segment and the decimal point.

Install a custom Arduino library using the Junos library manager, search the library repository, choose a version, and click install to add the seven-segment LCD display library to your project.

Identify the common leg of a common-anode rgb LED and mount it on a breadboard. Connect red, green, and blue channels, then test colors and blend them to form composites.

Explore the Arduino Leonardo with headers, highlighting its ATmega32U4 microcontroller, built-in USB for mouse or keyboard, and how its pinout and power supply differ from the Uno.

Explore the Arduino mega 2560 revision 3 hardware and its specs. Discover 54 digital i/o pins, 16 analog inputs, 256 kb flash, 8 kb RAM, and a 16 mhz clock.

Master the I2C protocol basics, including SDA and SCL lines, pull-up resistors, and master-slave communication, and explore its uses with displays and sensors.

Learn how to interface Arduino with I2C, SPI, and serial pins by identifying the I2C data and clock lines, SPI pins 10–13, and serial pins 0 and 1.

send data to the arduino serial pin and monitor it with the arduino serial monitor, using serial.begin(9600) and serial.print to debug ascii data.

Connect 16x2 and 16x4 LCDs to an Arduino using a wiring diagram, drive text with the liquid crystal library, control backlight with a potentiometer, and scroll hello world.

Connect an I2C module to an Arduino to drive a character LCD display, and use an I2C scanner program to detect and print device addresses on the serial monitor.

Learn the basics of max 7 2 x x based displays and how to daisy-chain multiple seven-segment displays with a microcontroller to display text.
