ELEGOO MEGA R3 The Most Complete Starter Kit
Starter kit that everyone can use to learn electronics
Electronics is not as complicated as you imagine especially with ELEGOO MEGA Starter Kit. For advanced users like professional lab engineers, electronic major students and experienced hobbyists compatible with Arduino projects, they can use this kit to do various kinds of tests and experiments with so many sensors available at hand.
What about novice users who don’t have any electronics knowledge? Fear not amigo. Just follow our tutorial enclosed and step by step you will come to realize that learning electronics is more fun than you ever expected with this amazing sensor kit.
It’s a good choice and perfect gift for your friends, family or kids who are obsessed with electronics or robotics to take their first steps on electronics journey!
The most complete starter Kit with high quality components and sensors
Quantity and quality are both important here in Elegoo MEGA starter kit. The most essential parts in this kit are MEGA controller board and expansion board, which is a perfect clone with excellent product finish Compatible with Arduino projects. Besides, we offer other over 60 kinds of components and sensors from small parts like LED diodes, resistors and potentiometer to big parts like LCD1602, RFID module and 830 tie-points breadboard, which meet your demands for your different projects either it is simple or complex.
Sturdy quality is definitely the most important thing to Elegoo even with so many components provided we never compromised on the quality. Instead we keep improving our product quality in our own factory and we produce the products by ourselves under high standards and strict quality control. Pins and wires on some of the parts like LCD16502 and motors have been pre-soldered which is very convenient and saves your time.
LCD1602 Display module
LCD1602 module is a display that has an LED backlight and can display two rows with up to 16 characters on each row. You can see the rectangles for each character on the display and the pixels that make up each character. The display is just white on blue and is intended for showing text.
Lining up the display with the top of the breadboard helps to identify its pins without too much counting, especially if the breadboard has its rows numbered with row 1 as the top row of the board. Do not forget, the long yellow lead that links the slider of the pot to pin 3 of the display. The ‘pot’ is used to control the contrast of the display.
DC Motors and L293D Transistor
In this project you will learn how to control a small DC motor using a Mega board and a L293D transistor, which is a very useful chip. It can actually control two motors independently. We are just using half the chip in this lesson, most of the pins on the right hand side of the chip are for controlling a second motor.
L293D is quadruple high-current half-H drivers and designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is also designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V and drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
74HC595 Shift Register 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.
