If you want to understand Arduino, you have to talk about its origin.
The name Arduino is rumored to come from a bar in Ivrea, Italy, where some of the founders of the project frequented. The bar is named after Arduin of Ivrea, Margrave Count of Ivrea and King of Italy from 1002 to 1014.
Arduino was launched in 2005. Designed to provide novices and professionals alike with a low-cost and easy way to create devices that use sensors and interact with devices. environment. Beginners and hobbyists can use Arduino to build devices such as sensors, simple robots, thermostats, and motion detectors.
For beginners, a low-cost and simple-to-operate board is undoubtedly very attractive, and it has quickly emerged around the world.
Let’s first briefly understand the characteristics of Arduino:
It is based on the open source circuit diagram design of Chuangyong CC.
It can be downloaded for free, and you can modify it according to your needs, but you must follow the name tag and give credit to the author or licensor in the manner specified.
Arduino can use the ICSP online burner to burn the bootloader into the new IC chip.
You can obtain the hardware design files from the Arduino official website and adjust the circuit board and components to meet your actual design needs.
It can be easily connected to sensors and various electronic components, such as infrared, ultrasonic, thermistor, photoresistor, servo motor, etc.
Supports a variety of interactive programs, such as Adobe Flash, Max/MSP, VVVV, Pure Data, C and Processing, etc.
Use a low price microprocessor controller (Atmel AVR) (ATmega8, 168, 328, etc.).
USB interface, no external power supply required. In addition, direct current (DC) power input is provided.
Below is a detailed description of each pin of the Arduino driver board:
With the Arduino board, you can develop or expand a variety of functions on it. For example, the XiaoR GEEK DS video smart car uses an Arduino motherboard. It uses wireless video transmission technology to watch the pictures captured by the car's camera lock in real time. It is also equipped with ultrasonic, infrared and other sensors, with infrared patrol lines and ultrasonic ranging back. Of course, the open underlying source code is available for transmitting and other functions. The most important thing is that it is compatible with up to 45+ different sensors, which means that on this small robot, you can experience hundreds of different arrangements combination gameplay.
