在此处了解如何使用万用表。 无符号 int 类比读取 = 类比读取(A1)*4 ; 6. 此外,变量analogread的电压值使用以下公式计算 浮动opvolt = (5.0/4096.0)* 模拟读数; 7. 以下语句用于开始使用 MCP4725 进行传输 Wire.beginTransmission(MCP4725); 将控制字节发送到 I2C Wire.write(
How to convert old MSB first 32 bit IR data codes to new LSB first 32 bit IR data codesFor the new decoders for NEC, Panasonic, Sony, Samsung and JVC, the result IrReceiver.decodedIRData.decodedRawData is now LSB-first, as the definition of these protocols suggests! To convert one ...
Update to LittleFS 2.5.1 (#8543, #8786) Fix File::readString to work with binary data (#8742) Add FSTools with examples of how to convert between SPIFFS and LITTLEFS. (#7696) Correctly using fs:: namespace in SD & SDFS (#8493) Move ESP8266SDFat library to master, not branch (#846...
Softwareprograms, calledsketches, are created on a computer using the Arduinointegrated development environment (IDE). The IDE enables you to write and edit code and convert this code into instructions that Arduino hardware understands. The IDE also transfers those instructions to the Arduino board (...

On the first line, there's a new expression 'int delayTime = 200;' This is the so-called declaration of the variable 'delayTime'. A variable is just a piece of memory, where you can store pretty much anything you like. A variable has adata type, a name, and a value: in this ca...
What the 4511 does is takes a 4 digit binary input value (ones and zeros), and converts it to a decimal value on a seven segment display, it's a really handy chip. In this instructable I'll show you how to use them with the arduino. Step 1: Materials Parts: 1.) Arduino 2.) ...
