Build Arduino schematics & code


Project Overview


I need a simple program that can do the follow:

1) connect to wifi

2) read light sensor input

3) send an http PUT request that contains the information listed in the next section. (should be sent once every 10 minutes)

It will need a protocol to connect to it before it is on wifi to give it the ssid and password of the wifi.

The circuit should contain an on/off switch and the ssid/password needs to persist once set.

The device be able to receive http requests to preform the following tasks:

- start/stop sending of PUT request

- change wifi ssid / password


PUT Request Data


bri [uint8]

=> Brightness of the light. This is a scale from the minimum brightness the light is capable of, 1, to the maximum capable brightness, 254.

hue [uint16]

=> Hue of the light. This is a wrapping value between 0 and 65535. Both 0 and 65535 are red, 25500 is green and 46920 is blue.

sat [uint8]

=> Saturation of the light. 254 is the most saturated (colored) and 0 is the least saturated (white).

xy [list 2..2 of float 4] (ie [0.1234, 0.4321])

=> The x and y coordinates of a color in CIE color space. The first entry is the x coordinate and the second entry is the y coordinate. Both x and y are between 0 and 1. For more information on CIE color space see: [login to view URL]

ct [uint16]

=> The Mired Color temperature of the light.




I would like to use the following components:

-> Arduino Pro Mini <-

-> ESP8266 WiFi chip <-


-> TCS34725 RGB Light Color Sensor <-


Feel free to use other components as necessary.


Completion Criteria


I will require a Fritzing design (see below for example) and code that I will build and test locally to be considered complete.

Hello. Arduino is not necessary for that project. You may use ESP8266-based board NodeMCU - that will perfectly work with the sensor without Arduino. I also have used color sensors in the past.
