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:
The TMP36 was my first sensor and is pretty simple. 3 pins, 1 analog port.
Available from SparkFun.
It’s a low voltage temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn’t require any external calibration to provide a typical accuracy of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. Give the it a ground and 2.7 to 5.5 VDC and read the voltage on the Vout pin. The output voltage can be converted to temperature easily using the scale factor of 10 mV/°C. For Example:
I’m not liking the button on an interrupt idea for the temp project. I’m working on a timer interrupt instead. Stay tuned.
I get questions all the time about paper sizes, European equivalents and how to convert sizes. I decided to make this quick and very dirty mashup.
It basically shows all the standard cut sheet paper sizes you’re most likely to encounter in the world, or at least in the office environment. It also covers weights and lots of visual comparisons of sizes.
