The second: If the input state is changed from LOW to HIGH (or HIGH to LOW), do something. Depending on the application, we choose one of them. For example, in case of using a button to control an LED: If we want the LED to be ON when the button is pressed and OFF when the ...
The IP Address is the IP Address of your PC, or the IP Address of another PC not connected . Select any port you want, 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 t...

First, the connection between SCL and SDA is the same as Demo 1. Then the port 2 is INPUT while the port 9 is OUTPUT. Whether the button is pressed, the current flows from port 9 and must return to GND after passing LED, and according to the reception message to control the switch ...
mouse cursor. Perhaps you want to move the mouse position in response to Arduino information. For example, suppose you have connected a Wii nunchuck (seeRecipe 13.2) to your Arduino and you want your hand movements to control the position of the mouse cursor in a program running on a PC....
(Mini). I do not recommend the latter if soldering by hand. The LEDs require one pin from Arduino to control all of them. From the datasheet it would need one external 100nF decoupling cap for each of the Neopixels. Remember from theCapacitorssection that these are used to remove the ...
4 wire SPI means the display must have SPI interface comaptible signals and a "Data/Command" control signal, this signal line is sometimes labelled DC, RS or A0. Due to lack of GPIO pins the 8-bit parallel interface is NOT supported on the ESP8266. 8-bit parallel interface TFTs (e....
