The kit contains more than 120 components and electronic modules, these components can be divided into about 30 species. We have carefully prepared a Tutorial, and supporting experimental code routine for you to learn. The Tutorial includes 27 experiments, and the code. Through the learning, you will get a better understanding Arduino Uno R3, and will be able to make fascinating works based on Arduino. /////// Project 1 Blinking LED, Project 2 LED Flowing Lights, Project 3 Controlling an LED with a button, Project 4 Tilt Switch, Project 5 Active Buzzer, Project 6 Breathing LED, Project 7 Passive Buzzer, Project 8 Controlling a RGB LED with PWM, Project 9 7-segment display, Project 10 Photoresistor, Project 11 Photoresistor controls LED, Project 12 Thermistor, Project 13 Temperature alarm, Project 14 Electronic organ, Project 15 LCD1602, Project 16 IIC Interface module, Project 17 LCD1602 Display Photoresistor data, Project 18 Frequency meter, Project 19 Rotary Encoder Module, Project 20 Rotary Encoder controls RGB, Project 21 LCD1602 display the value of the rotary encoder, Project 22 Ultrasonic Distance Sensor, Project 23 11.2 LCD1602 display Ultrasonic value, Project 24 Photoresistor Control picture brightness, Project 25 Processing Control RGB, Project 26 Processing Detect Ultrasonic data, Project 27 Processing pong. /////// Package List: 1x Arduino UNO R3 Board, 1X Rotary Encoder Module, 1x DC Motor, 1x L293D motor driver, 1x LCD1602, 1x I2C Interface Module, 1X Ultrasonic Distance Sensor, 1x 7-Segment Display, 1x NE555 Chip, 1x Passive Buzzer, 1x Active buzzer, 2x Photoresistance, 2x Thermistor, 2x Tilt Switch, 2x Switch, 1x RGB LED, 4x Red LED, 4x Green LED, 4x Yellow LED, 4x Blue LED, 16x Resistor(220?), 10x Resistor(1 K?), 10x Resistor(10 K?), 5x Capacitor (104pf), 2x Capacitor (10uF), 4x Button (large), 8x Button (small), 1x Button cap (Red), 1x Button cap (White), 2x Button cap (Blue), 2x NPN Transistor(8050), 2x PNP Transistor(8550), 2x Potentiometer(10K?), 1x 9V Battery Holder, 1x Breadboard, 1x USB Cable, 40x M-Male Jumper Wires, 20x M-Female Jumper Wires, 1x 4-Pin Wires, 1x 5-Pin Wires, 1x Band Resistor Card.
