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.

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 port...

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...
If you must, ALWAYS // connect GROUND (-) first, then +, then data. // - When using a 3.3V microcontroller with a 5V-powered NeoPixel strip, // a LOGIC-LEVEL CONVERTER on the data line is STRONGLY RECOMMENDED. // (Skipping these may work OK on your workbench but can fail in the...
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...
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...
If you use a microcontroller and a separate board with the SX126x transceiver you need to define the hwConfig structure to define the GPIO's used to connect the two chips. If you use the Insight SIP4520 or the RAKwireless RAK4630/4631 modules the connections between the chips are fixed. ...
