Feature:    The starter kit that everyone can use to learn electronics and programming.  Electronics is not as complicated as you imagine especially with this MEGA 2560 Starter Kit. For advanced users like professional lab engineers, electronic major students, and experienced hobbyists, they can use this kit to do various kinds of tests and experiments with so many sensors available at hand.  It’s a good choice and perfect gift for your friends, family or kids who love electronics, programming 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 this MEGA 2560 starter kit. The most essential parts in this kit are MEGA 2560 controller board and expansion board, which is a perfect clone with excellent product finish. Besides, we offer other over 60 kinds of components and sensors from small parts like LED diodes, resistors, and a potentiometer to big parts like LCD1602, an RFID module, and 830 tie-points breadboard, which meet your demands for your different projects either it is simple or complex.   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 UNOR3 and an 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.     Package includes:    25 x LED ( white, yellow, blue, red, green).  1 x RGB LED .  10 x Ceramic Capacitor (22pf & 104pf).  2 x Photoresistor.  1 x Thermistor .  5 x Diode Rectifier (1N4007) .
