TheanalogRead()command converts the input voltage range, 0 to 5 volts, to a digital value between 0 and 1023. This is done by a circuit inside the microcontroller called ananalog-to-digital converterorADC. 模拟读 analogRead 命令将输入电压 0 至 5 伏特转换到数字值域,从 0 至 1023.这是通过...
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 ...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts. The power pins are as follows: Vin. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection...
