A project using the AmazonDRS library for WiFi101 connected Arduinos. Just like the AWS IoT button, but completely open source! Things used in this project Story TL;DR; Buy some stuff on Amazon by clicking a pushbutton connected to your WiFi101 enabled Arduino. It’s like a Dash button, but cooler! Motivation Back in the Spring of […]

Pulse sensors have become popular due to their use in health-monitors like the Fitbit. The sensors used are cheap, simple and pretty reliable at getting a reasonable indication of heart rate in daily use. They work by sensing the change in light absorption or reflection by blood as it pulses through your arteries — a technique

The AFBR – S50 is a multipixel distance and motion measurement sensor. It has an integrated 850nm vertical cavity surface emitting laser (VCSEL) which uses a single voltage supply of 5V. It’s measurement rates are quick and as fast as 3 kHz, which is a distinguishing feature. However, this is not the reason why the

Introduction A data logger is an electronic device or instrument that records data over a period of time. It allows the user to record time or location stamped data which can be viewed at a later time or real time. Irrespective of the type of data being logged or the kind of data logger, these devices usually

With all the different ways capacitors are labeled, figuring out the values of your capacitors can be challenging. Especially if you don’t have a digital multi-meter to test them. In this tutorial, I’ll show you how to build three different capacitance meters using an Arduino and a couple resistors. After finishing this project, you’ll be able to measure all
