I found time over the holidays to mess with one of my old original projects- the Tri-Temp It was very interesting to poke around in some of my original hardware/code and add some things to it. Attached is a gallery of pics from the latest incarnation. I'll add the code changes and an updated schematic … Continue reading Tri-Temp Update
I haven't worked on the Tri-Temp project in a while. I am going to go through and update the code a bit to lower the memory usage based on what I've learned for the LCC projects. The original LCC code will have an update posted soon too. Mostly memory updates and a few control changes. … Continue reading Code Updates
Here are pics of the update Tri-Temp case/labels.
After a long wait here's version 2.0 of the Tri-Temp Standard code. What changed? Lots. Button response is now very very fast. Button to toggle C/F temp measurements Temp reading is updated by interrupt timer. Approx every 5 sec. Code is documented Two new libraries needed - avr/interrupt.h and TimerOne.h Here's the code:
On my last project- which still isn't done yet- the buttons for changing the temp display are very unresponsive. The reason of course is because the Arduino has to loop through all the main code before getting around to checking the button status. I found the cure! Interrupts! EngBlaze has a great write up on … Continue reading Slow Button/Switch Reaction
It occurred to me that the tri-temp project doesn't have to be limited to the DHT22 sensor. Duh! What is attached to the three externally accessible ports is totally up to software. I think maybe I'll add a pressure sensor too.
This is the first version of the Tri-Temp code. If you find any errors or add any features let me know so I can update it.

Description This is the Tri-Temp project. It comes in two flavors- Standard and Ethernet. The Standard version outputs all readings on an LCD. The Ethernet adds output to HTML via a web browser. I did not design this to use an Ethernet shield- only the Arduino Ethernet- it's more compact.So what's this all about? Reading … Continue reading Tri-Temp Project Intro
Coming soon- the mostly completed Tri-Temp box. Two editions- Standard and Ethernet. I'm still finishing it up and have lots of pictures. Measure temperature and humidity from three locations via digital probes Self contained in a small project box Standard uses Arduino UNO Ethernet uses Arduino Ethernet Uses 16x2 LCD to display on Standard version … Continue reading Tri-Temp project
