Infrared Rangefinder

Homemade Infrared Rangefinder (Similar to Sharp GP2D120) using Arduino

Leave a Comment / Using Arduino / By

Here is my instructable on how to construct a pretty simple (for some!) short range infrared rangefinder/range sensor. Infrared rangefinders are very useful in a number of projects. The majority of these come from obstacle detection (in robots) or generally detecting distances! The one shown here is only a simple rangefinder and will only really …

How to use a while loop to calibrate the value of an analog sensor using Arduino

Leave a Comment / Using Arduino / By

Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while loop to calibrate the value of an analog sensor. In the main loop, the sketch below reads the value of a photoresistor on analog pin 0 and …

How to Make a Tactile Feedback Compass Belt using Arduino

Leave a Comment / Using Arduino / By

Have you ever wondered how migratory birds manage to have such an amazing sense of direction despite being so generally clueless? They can sense the Earth’s magnetic field with what is basically a compass built into their body. Wouldn’t it be cool to feel what that’s like? The following instructions are loosely based off of …

Arduino Quasi real time oscilloscope

Quasi real-time oscilloscope using Arduino

Leave a Comment / Using Arduino / By

Recently I was reviewing one of my oldest project, and decided to “refresh” previous design by taking full advantage of the new arduino Leonardo board.  Based on AtMega32U4, which include PGA (programmable gain amplifier), oscilloscope’s  analog front end doesn’t require external OPA this time, end could be build in 1-2 hours on prototype board, using 5 …
