Use a Particle Photon board to subscribe to channel updates from the CheerLights channel. The program reads a color from the channel and displays it using on the built-in LED on the Photon board. You can subscribe to the channel feed or directly to the color field on the CheerLights channel as shown in this example.

Collect environmental data from a device and post it from your device to a ThingSpeak™ channel. The example uses an ESP8266 and the ThingSpeak Communication Library to post data and retrieve data from a channel.

Post multiple fields of data to a ThingSpeak™ channel from a device that wakes from deep sleep. You read a soil moisture sensor and post the value to a ThingSpeak channel. The HTTP POST request is executed by writing to a communication client without a separate library. Directly writing the HTTP request to the wireless network client can offer increased flexibility and speed over the ThingSpeak Communication Library.

Use the wireless network functionality of ESP32 to post data to ThingSpeak™. The ESP32 records and posts the signal strength of the wireless network that it is connected to. Press a button on the board to take three measurements of the wireless network signal strength and post the average result to a ThingSpeak channel. The device also posts a counter value so you can track measurements.
