This example shows you how to read analog input from the physical world using a potentiometer. Apotentiometeris a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your board, it...
示例名称为 AnalogReadSerial,专注于串口模拟读取。该示例从针脚 0 读取模拟输入,并将结果打印到串口监视器。若未连接开发板,执行代码会报错。正确连接电位器至针脚 A0,外侧针脚至 +5V 和接地,便能完成示例的硬件搭建。代码示例位于公共域。示例代码分为设置函数(setup)和循环函数(loop)两部分。在...

/* read a rotary encoder with interrupts Encoder hooked up with common to GROUND, encoder0PinA to pin 2, encoder0PinB to pin 4 (or pin 3 see below) it doesn't matter which encoder pin you use for A or B uses Arduino pullups on A & B channel outputs ...
sensors such as to find out the temperature of the room, the input values are in analog. These values can be read by the Arduino from its specific pins and these values can be used for further use. But before understanding the analogRead(), we have to understand what is the analog ...
uint32_t xvalA1; // like original analogRead but plus fast (if only 1 or 2 Pin enabled else + slow) xvalA0 = DueAdcF.ReadAnalogPin(A0); xvalA1 = DueAdcF.ReadAnalogPin(A1); // ReadAnalogPin wait for the PIN measurement to be available in the buffer // and returns the value, ...
Girino - Fast Arduino Oscilloscope: I am a Physicist and the nicest part of working in this field is that I get to build my own instruments. With this way of thinking, I decided to build a homebrew Arduino Oscilloscope. This instructable was written with
