This library is a fork from scogswell's library. The main intention of this library was to implement a device able to respond to AT Commands, for example "AT", "AT+RST", that kind of commands you see ...

JsonDocument作为整个V6版本ArduinoJson库的内存入口，负责处理整个json数据的内存管理，这是我们需要首先重点关注的内容。 创建一个JsonDocument之后，默认初始化为空，调用 JsonDocument::isNull()会返回true，这个时候既可以代表当做jsonObject，也可以当做jsonArray，这取决于 ...

Many times like a multimeter, I expected to have a handy serial terminal nearby such that I will connect those two wires [Tx, Rx] of the probe and will be able to see whether the sensor is really ...

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects. In order to program your ...

This library provides a basic "command line interface" for your Arduino through its serial interface. This can connect to the Serial Monitor, for example. Commands are of the old (1970s) Unix-style ...

Update, 1/2/21: It's New Year's weekend, and Ars staff is still enjoying some necessary downtime to prepare for a new year (and a slew of CES emails, we're sure). While that happens, we're resurfacing ...

Assemble yourself a portable, four-channel multi-mode light controller using an Arduino Uno board and very few external components. The fancy lights controller described here is built around the ...

This is the simple method to setup serial communication between Arduino and MATLAB. Here we will simply send the data from MATLAB to the Arduino serially using command window and then Arduino read the ...
