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
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...

arduino leonnardo和uno 这两个板子的CPU不一样,Leonnardo用的是ATmega32u4,UNO用的是ATmega328。最大的区别是在USB上面,Leonnardo的USB接口是CPU原生的,而UNO是通过ATmega16u2转的。这导致它们在使用上有一点微小的区别。Leonnardo可以模拟成USB的键盘,鼠标,而UNO不行。如果使用串口功能,由于Leonardo是CPU直接连接USB,...
An Arduino UNO microcontroller based digital voltmeter has been designed and developed with liquid crystal display and voltage range indicator. A regulated low voltage power supply circuit (5 volt) has been developed to power up Arduino microcontroller. Arduino senses the input voltage, converts the ...

在本教程中,我们将MCP4725 DAC IC 与 Arduino Uno 连接,并使用电位计为 Arduino 引脚 A0 提供模拟输入值。然后ADC将用于将模拟值转换为数字形式。之后,这些数字值通过 I2C 总线发送到 MCP4725,以使用 DAC MCP4725 IC 转换为模拟信号。Arduino 引脚 A1 用于从引脚 OUT 检查 MCP4725 的模拟输出,最后在16x2 LCD...

it would take different times depending on the input voltage! Note: As the number of bits in the ADC increases so does the acquisition time. Arduino Uno ADC resolution As we saw earlier the resolution of the ADC, when Vref=5V is 4.88mV per step. The Arduino analogRead resolution which is...
Select the ‘Arduino Uno’ board, which is what we will be using Let’s Start Coding! The First Arduino Code Sample If the IDE hasn’t already created a new project for you, create a new one via theFilemenu and it should create two functions for you named ‘setup‘ and ‘loop‘. Th...
