This instructiable builds onUsing ESP8266 GPIO0/GPIO2/GPIO15 pinsto show you how you can get four (4) usable inputs/outputs for you next ESP8266-01 project and how to use IC2 to get even more inputs. It also co
To detect the wake-up, an LED will blink after the ESP8266 wakes from any given sleep mode. For this to work, connect an LED to the GPIO2 as shown below. To place ESP8266 into the modem sleep mode and later wake from a timer, use theespmodule. This MicroPython script puts ESP8266...
The WS2812 LED strips are often found on the Internet, which are also somewhat cheaper than the WS2801 models. However, these are not all too good for the Raspberry Pi, since the onboard audio output of the Raspberry Pi can not be used anymore. However, I will write another tutorialon ...

Picking the HUZZAH ESP8266 naturally led me to exploreAdafruit IO. However, this choice was not made without a few criteria: integrated board and cloud experience, minimal need for configuring connectivity to the cloud, ability to customize the UI to view data, ...
Raspberry Pi Pico has a lot of interesting and unique features, but it doesn’t have networking. Of course this was only ever going to be a temporary inconvenience, and sure enough, over Pi Day weekend we saw bothUSB EthernetandEthernet PHYsupport released for Pico and RP2040. ...
For this tutorial we have two examples. The first example is controlling a simple LED and the second one is controlling a Stepper Motor using smartphone. In myprevious tutorialwe already learned how to make the Bluetooth communication between the Arduino Board and the Smartphone...
I also think this MUST be possible without using dual core threads.. But I don't want to send text. I just want to send "192.168.2.81/A" for example to make the ESP8266 turn on the lights. The HTTP protocol requires that you send text to the server in order to access an URL...
1. Power on the receiver and wait for 60 seconds. The LED light of the receiver will flash, indicating that it has entered WIFI mode. Then turn on the WIFI of the computer, find Wifi named:ExpressLRS RX, and input the password ”expresslrs“ ...
