Platform IoT Cayenne Mydevices & ESP8266 12E NodeMCU

This time the test is performed on the well-known Cayenne platform.

What is Cayenne? It is a solution for building IoT applications based on platforms known as Arduino, Raspberry pi, ESP8266 and Serial devices,Wi-Fi, Lora devices, also includes a Mqtt API to connect any MQTT client which to use in this case, in This tutorial will explain the following: This tutorial will take a tour of the Cayenne platform.

1- Create a Starter account in cayenne

2-Download libraries and examples

3- Modifying Arduino IDE Examples

Step 2: Signal Conditioning & Arduino IDE - Components and Materials Required for Testing

ADC(0) Signal Conditioning

You must be very careful when using ADC (0) pin ESP8266 12E, TOUT, ADC (0) or pin 6 are some names by which this input will be identified, its resolution is 10 bits from 0 to 1.0V maximum, We have created a circuit based on a voltage divider and a diode to limit the input voltage in parallel to our light sensor, photoresist or LDR.

Arduino IDE

During tests it is denoted that cayenne allows to send values and the dashboard allows to preview the value and it facilitates when adding the associated widgets to that value. For the control of the Led in Arduino IDE, the function log of cayenne by default is configured, which technically listens to the parameters of any channel that sends data from Cayenne to the ESP, in this case the widget button. It takes the value of the channel assigned to the button and that value goes from String to int to activate the GPIO 04.
