Touch screens are two dimensional input devices. Nowadays most of the electronic gadgets use them. Laptops, smart phones, tablets and even some home appliances like washing machines & microwave ovens also use a touch screen nowadays. Why Touch screens? Touch screens are preferred over keypads because they need very little or no pressure to operate whereas …

Many times we are faced with a heat containing coffee and don’t know if the fluid is at the proper temperature and it is impossible to know just by looking at the bottle ended up losing time with a coffee that is cold and we get upset about it. This however indicates maker by a …
I was looking at all those swoopy-zoomy internet connected and controllable thermostats. “Self,” I told myself, “we should make one of those.” He didn’t seem all that excited about that – I mean, what do we know about hardware, firmware, electronics or HVAC? Well, now’s as good as any to figure it out. So without …
Lab Experiments involving the Heat Equation are usually one-dimensional exercises involving a copper pipe and a half-dozen thermocouples. But with DS18B20 “One-Wire” thermometer chips and an Arduino, it’s possible to measure hundreds of temperature values simultaneously. Here’s what my students Daniel Lund and Lawrence Lechuga and I came up with for 2-D temperature measurements. We began by …

I have been researching a project which will help me with my understanding of electronics, networking, and programming. I decided to build an online thermometer which could be used in applications that need temperature monitoring. I currently work in a lab environment where I test, troubleshoot, and calibrate equipment which is installed in nuclear power plants …
The one wire Digital Temperature Sensor – DS18B20 from Maxim (formerly Dallas) is a great chip for measuring temperature in your projects. Luckily, there is a Dallas Temperature library for the arduino which makes using this sensor very easy. The most recent version of this library can be found at http://www.milesburton.com/?title=Dallas_Temperature_Control_Library We used version 3.6.0 …

You are building a soil temperature sensor. We need a waterproof thermometer that we can burry in the soil. The sensor is made up of a small circuit enclosed in a piece of heat shrink (to waterproof it). Supplies: (see the parts page) an LM335 temperature sensor a 33K and a 56K resistor a short piece …
My wireless temperature probes work by using an Xbee module to transmit readings from a TMP36 down to the Arduino base station. The XBees aren’t too cheap, coming in around £19 or $23 so I tried to be cheap and ordered mine from Sparkfun, I bought this XBee (series 1) with Chip Antenna and these breakout boards. I …

Everyone has USB gadgets. It’s pretty much a fact of life. Another fact of life is that these USB gadgets also continually run out of power when you most need them. No need to fear, solar power is here! Ditch those crazy wall adaptors, throw out the laptop, and start making your own solar charger! …
