A note on what this document covers The key addition to the wealth of online information about pulse counting is the method of counting pulses from multiple sources (up to 12) using continuous sampling and direct port manipulation in an Arduino sketch instead of interrupt-based counting. When tallying pulses from one or two pulse output […]

My close friend, who works as a teacher, was conducting quizzes in her class that involved students competing to answer questions. This caused some students to complain about not getting a chance to answer even though they had raised their hands first. I chose to gift her with a buzzer similar to those used on

I’ve been in possession of an Arduino Duemilanove for a couple of weeks. If you are unfamiliar with the Arduino, it is defined as “a platform for creating electronics prototypes using adaptable, user-friendly hardware and software”. The setup consists of a small microcontroller, a USB port for programming on a computer, a power socket for

DIY wattmeter with an Arduino Measuring power and energy using regular multimeters can be challenging or even unfeasible at times. In order to conduct such a precise and reliable measurement, a specific wattmeter is necessary. Due to their high cost, an alternative option is introduced in the form of a homemade wattmeter using an Arduino

https://github.com/stirobot/arduinoModularTFTgaugesI built a custom OBD II (on board diagnostics version 2 http://en.wikipedia.org/wiki/On-board_diagnostics) The clock in my Subaru BRZ (GT86, FRS) was a popular feature, and many people asked me to make one for them. This is how you can construct your own. My spouse is close to delivering our second son and since all the

People love listening to music while exercising. Music provides the motivation needed for individuals to keep exerting energy and get in shape. So, because people enjoy listening to music while exercising, what if an MP3 player only played an individual’s music while they are active? Using music as an incentive to continue exercising would encourage
