Arduino Unois a microcontroller board based on 8-bit ATmega328P microcontroller. Along with ATmega328P, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller. Arduino Uno has 14 digital input/output pins (out of which ...

将多个LED以“共阳”接法连接起来,再将多组“共阳”层叠起来,每层负极相连,组成一座灯塔,电路原理类似于LED点阵,各层的正极与负极分别连接Arduino UNO的I/O 端口,见图1: 图中R1——R5为限流电阻,Arduino UNO 各端口可以输出20mA 电流,为确保LED的使用寿命,中间串联100——330欧姆的电阻,五个LED的正极端与Ardui...
An Arduino core for ATmega8535, ATmega16, ATmega32, ATmega164, ATmega324, ATmega644 and ATmega1284, all running theUrbootbootloader. Most Arduino UNO-compatible libraries will work with this core. If not, it's fairly straightforward toport a library. This core requires at least Arduino IDE v1....
In the image above, you can see the entirepin mappingof the Arduino Uno, the port numbers are in the yellow fields next to the pins. (image credit) Since every bit of the byte represents one pin, it is easier to write the values inbinary notation. You can do this by adding a capit...

And also compatible with all Arduino shields and components used on the Arduino Uno, provided that the Pin-out is the same, a practical example is that we can connect the Ethernet shield used on the Arduino Uno since the pin-out is perfectly compatible as shown in the figure....
The largest one, the ATmega4809 can be found in products like the Arduino Uno WiFi Rev2 and the Arduino Nano Every. Some of their key features include multiple serial ports, SPI and i2c interfaces, built-in programmable logic, up to 16 analog input pins, and an analog comparator with a ...
