Note: On the Nano you get 2 more analogue inputs. This is because on the Uno the A6 and A7 pins are not routed to the pin headers - they are routed on the Arduino Nano. NOTE:There are 2 other I2C connection pins on the header. ...
Pins marked as D14-D21 or A0 - A7 can both transmit and receive voltage values and there are also called General purpose Input/Output (GPIO) pins. The GPIO pins (D14-D21) can behaves as analog pin and Digital pins depending on how we configure it. Note:You must never apply more th...
In this chapter, we will learn a bit more about analog input using a device that lets us set a dial angle position to tell the computer what we want it to do. This device - a potentiometer - will also help reinforce our understanding of Ohm's law and circuits, while providing a very...
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...

The microcontroller of the board has a circuit inside called ananalog-to-digital converterorADCthat reads this changing voltage and converts it to a number between 0 and 1023. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value...
