I am working on a project that works with two arduinos. One arduino contains a stepper motor and a servo motor. While the other one only has a stepper motor. However, every time I run my program I always get a, "Error uing serialport". Here is my program: %Clear exisiting por...
Chapter 1described how to connect the Arduino serial port to your computer to upload sketches. The upload process sends data from your computer to Arduino and Arduino sends status messages back to the computer to confirm the transfer is working. The recipes here show how you can use this commu...
however, if you are using Windows Server as the Operating System, remember to add an "In policy" in your Windows Firewall, otherwise, the ESP8266 is not allowed to connect to that Port.
How it works The Arduino board communicates with Tuya’s module that is flashed with general firmware through serial communication. Tuya’s module can send device data to and receive commands from Tuya. TheSmart Lifeapp can pair with the device and connect it to Tuya.Tuya_WiFi_MCU_SDKlibrary...

Pin Plugs:Apin plug, otherwise known as a jumper wire is a simple wire with a single plug on the end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will...
Connect the LED cathode to the same rail as the resistor. The cathode is the pin closest to the flat side of the LED. On some LEDs, this pin is shorter than the other pin (see Figure 4-4). 图4-4 LED polarity 将LED 阳极连接到另一个空的 5 引脚轨道。 将一根跳线从阳极的供电轨连接...
Connect a pushbutton or switch to digital I/O pin 2 with a 10K ohm resistor as a reference to ground. 通过10 千欧电阻将模拟传感器接到模拟输入针 0 和针 1。通过 10 千欧电阻连接一个按钮开关或者开关到数字针 2 并接参考地。 (4)电路示意图 - Schematic (5)代码解析 - Code 参考1。 (6)...
Join us for a hands-on webcast presented by Mike Westerfield author of Building iPhone and iPad Electronic Projects and see exactly how to connect an iPhone or iPad to an Arduino using a WiFi bridge, allowing you to control any Arduino project from your
