Arduino, DHT22, Webserver

November 30, 2014 5:54 pm

This was so far the most difficult Arduino project I’ve had to do so far. The goal was simple display some sensor data from a DHT22 temperature and humidity sensor. The code presented a number of problems. You can read the full run down how we got the working code here. The original code for this project was taken from Peter Oakes at this site.


You will find the code here:

Arduino, DHT22, and a LCD: Colour to Temperature

In this project we do an adaptation of rotating colour sketch and instead we use range of temperatures and assign each range a colour. So my idea is to do 15 Celsius or less would be blue, 15 to 25 degrees would be assigned the colour green and above 25 Celsius would be red.
I’d like to thank the folks at the Arduino and adafruits forums for all there help giving these sketches up and running.

There is the code:

Arduino, DHT22, and a LCD: Rotate That Colour

November 18, 2014 11:58 am

Welcome to my latest Arduino project. This project is based on the DHT22 temperature and humidity sensor. I’m using a 20×4 RGB LCD screen to output the data to. I got the idea that since the LCD can do RGB why not make it rotate through these colours while dislaying the data from the sensor. All parts used here are or where available from . the full sketch is below and if you have any comments leave them in the comments section below.
