The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and the analogReference() fun...

example to interface AT24C02 EEPROM with Arduino. Almost all Arduino development boards have at least one I2C port. Similarly,Arduino Unoalso has one I2C port which we can use to write and read data from this EEPROM chip. Connect the Arduino and EEPROM as shown in the interfacing diagram ...
#define TFT_RST 26 // Reset pin (could connect to RST pin)四、 代码在编写程序之前,首先需要对TFT_eSPI这个库中地部分定义更改以适应我的屏幕 ,找到User_Setup.h这个文件打开。 我们需要做如下改动,选择屏幕驱动,这里我的屏幕是ST7789驱动的 选择BGR配色方案,不然啃屏幕颜色会有一些反转 选择屏幕分辨率,...
Then, you can use an Arduino UNO to burn the "official" Pro Micro bootloader to your compatible board. After that, you can select Pro Micro directly in the IDE. Of course, you could also choose to take an easier route and simply use the Leonardo configuration. DigiSpark_SoftSerial_to_...
This configuration is found on the “standard” baseline Arduino boards built between 2007 and 2012. Boards using the newer “extended” pin layout (the Uno R3 and Leonardo), as well as the “Mega” boards, also support the baseline connections, but add new capabilities by extending the rows...
