ELEGOO UNO R3 Super Starter Kit

?100% Compatibility with Official Arduino Software, Sendsors and Codes

Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.

For the reason of open source, the manufacture of Arduino boards and software distribution by anyone is permitted. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.

Elegoo is one of the manufacturer on the market, whose clone products are 100% compatible with the official Arduinomicrocontroller boards, they can use the official Arduino software, sensors and codes.

?Learn The Science of Electronics with Arduino

The Arduino boards can be used as the brains behind almost any electronics project. Arduino can interact with buttons, LEDs, motors, speakers, GPS units, cameras, the internet, and even your smart-phone or your TV! By connecting the Arduino board with a personal computer via a USB cable and uploading to the board, users can create digital devices and interactive objects that can sense and control objects in the physical and digital world like robots or even honest fortune-telling machines.

For this Elegoo Super Starter Kit, we provide a 24-lesson tutorial, introducing the basic setting of the Arduino software IDE, the working principles of the sensors to enable the UNO board to control the sensors.

It’s a good choice and perfect gift for kids, teens, adults or whoever is obsessed with electronics, programming or robotics to take their first steps on electronics journey!

This Kit is suitable for 10-year-old and up. Younger kids should be under supervision and guidance of adults.

?74HC595 and LEDs

74HC595 is a Serial to Parallel Converter which has eight outputs (perfect) and three inputs that you use to feed data into it a bit at a time.

This chip makes it a little slower to drive the LEDs (you can only change the LEDs about 500,000 times a second instead of 8,000,000 a second) but it's still really fast, way faster than humans can detect, so it's worth it.

74HC595 shift register is a type of chip that holds what can be thought of as eight memory locations, each of which can either be a 1 or a 0. To set each of these values on or off, we feed in the data using the 'Data' and 'Clock' pins of the chip.

?4 digit 7 segment display

7 segment displays consist of 7 LEDs, called segments, arranged in the shape of an “8”. Most 7-segment displays actually have 8 segments, with a dot on the right side of the digit that serves as a decimal point.

When using 4-digit 7-segment display, the common anode or common cathode pin is used to control which digit is displayed. Even though there is only one digit working, the principle of Persistence of Vision enables you to see all numbers displayed because each the scanning speed is so fast that you hardly notice the intervals.

By building the circuit, users can make a simple display showing certain numbers, or more complexly, a count-up timer or a elecrical rolling dice.

?Stepper Motor

Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases". By energizing each phase in sequence, the motor will rotate, one step at a time.

With a computer controlled stepping you can achieve very precise positioning and/or speed control. For this reason, stepper motors are the motor of choice for many precision motion control applications.

the simplest way of interfacing a unipolar stepper motor to Arduino is to use a breakout

for ULN2003A transistor array chip, applying voltage to each of the coils in a specific sequence.
