Multimeters are suitable for many purposes. But usually, they only measure one value at a time. If we deal with power measurements, we need two multimeters, one for voltage and the second for Ampere. And if we want to measure efficiency, we need four multimeters. Here we will build small and inexpensive meters to do […]

There comes a time in life to put childish things behind and give up nasty habits. Some, like smoking, can be damn hard without constant encouragement. It was time for me to combine my favorite hobby with my driving goal and make this: The Quit Success Meter! For my other Arduino contraptions, take a look
Mint-Sized Success Meter (quit smoking!) with Arduino Continue Reading
I have a late 80’s VW and the gauge cluster has 5 dummy LED locations underneath the other warning lights. Well I was tired of the m not doing anything, so I decided to do something about it. I came up with the idea to put a lateral gravitational force mater (G Meter) in there

This is a simple project showing you how to make a digital voltmeter using Arduino where the readings are displayed in a Liquid Crystal Display LCD20x4. The proposed voltmeter design can read up to 50V. We are using analogue to digital conversion process. Arduino microcontroller equipped with 10-bit analogue to digital converter (ADC). This means

Hot Yet? Attiny85 Faucet Water Temperature Sensor Testing Real life testing in the kitchen sink! Note the tri-color LED. Blue is cold and fades into Green which then flips to increasing Red at 85F. Notes This project is an Attiny85 Arduino circuit and uses the Coding Badly attiny core available here: https://code.google.com/p/arduino-tiny/source/list For the

What’s all this? This instructable will explain how to build a fairly basic but working spectrophotometer out of easily sourceable parts. Of course, this device is nothing compared to a commercial spectrophotometer, but it will allow the builder to understand how such a device works. Huh? What are you talking about?! A spectrophotometer measures the

Previously, we introduced the Arduino’s analog-to-digital converter (ADC) in detail, looking at successive-approximation A-D conversion and how it’s the best compromise between speed and cost. This time, we start putting some of that theory into practice by building a stereo peak-program meter. Our Peak Program Meter (pictured above) takes audio from any phone or tablet.

I recently needed to measure how different materials affect light transmission for a gardening project. I decided this was the perfect opportunity to try out the new logic level converter to run both a 5v LCD and a 3.3v light sensor on a single i2c bus. I used the following parts in this project: Arduino
