Infrared Rangefinder

Homemade Infrared Rangefinder (Similar to Sharp GP2D120) using Arduino

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 …

Measure RPM Optical Tachometer

Measure RPM – Optical Tachometer using Arduino

This Instructable will show you how to make a Portable Digital Optical Tachometer using an Arduino Uno. This project is inspired from This instructable and is an enhanced version of it with an LCD display and a modified code. Instead of a slotted sensor , it has a reflection based sensor. So : 1. You don’t have to worry about the …

Arduino Cannot get ECG readings from heart

Arduino – Cannot get ECG readings from heart, but I do when I poke at the leads

down vote favorite I have a minor issue with my ECG. When I poke at the leads, I get a reading. But when I hold the leads or place it near my heart, I don’t get anything. I’m pretty sure this is hardware related, but I don’t want to completely rule out a potential software problem. …
