【Supplement for Old Tutorials】Basic C language grammar teaching has been added. Whenever new knowledge points are involved in the course, there will be corresponding popularization. Improved FAQ, use a more convenient way to add a library for the common error of "lack of library". Added tutorial for building development environment under Ubuntu.

【New courses】Many new projects are added in the course like Dice roll, Retro Snaker, Memory Game, Bean Game, Alarm Clock, Time Recorder, Induction night light... which is quite fun and interesting. Everyone can learn electronics and programming while playing.

【Perfect gift】All parts are packaged in an attractive, convenient container. It’s a good choice and perfect gift for your friends, family or kids who are obsessed with electronics, programming or robotics to take their first steps on electronics journey!

Compatibility with: Arduino UNO R3 Mega 2560 1280, Arduino CCTV. Works with devices require 9V and 1000mA of DC power and physically fits the plug. Please make sure the connector size 5.5x2.1mm can fit your applications before purchase.

DOES NOT fits Effects Pedals, Drum, DJ controller, Piano keyboards, Label makers and other equipment with power ports of negative-tip. Not applicable for devices that withstand minimal electromagnetic interference, such as radio set.

Improved and expert version: 1. 0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Due that operate with 3. 3V. The second one is a not connected pin, that is reserved for future purposes.

Stronger RESET circuit. Use 5. 5 * 2. 1mm DC barrel jack (compatible with 5. 5 * 2. 5mm DC barrel jack)

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

With a precision potentiometer, better quality, power supply module and breadboard

With jumper wire and f-m DuPont wire

Not including the controller board

Lcd1602 module and gy-521 sensor module with pin header ( no need to solder by yourself)

Nice package with clear listing and surprise including a nice small box to keep the widget such as LED, IC, buttons, diodes, etc.
