In this project, we will go over how to build a vibration detector circuit.This is a circuit which can detect and measure flex, touch, vibration, and shock.The sensor we will use to detect these movements is a piezo vibration sensor from Measuremenet Specialists (MEAS). The sensors are a thin strip of piezoelectric material with a

This is how to push high resolution real-time data from Arduino-based temperature sensor to your web page without any server-side coding. Arduino is a great device for collecting, storing and transferring data from various sensors but there are times you need to make your data accessible from any place over the internet, like I did

In this tutorial you will learn how to turn any conductive surface into a capacitive touch sensor. This project illustrates how to use capacitive touch to turn on a motor (fan) and neopixel. In this example, all of the components were custom designed and built specifically for this application. Since this method can be used
For a while I have been looking for a way of getting a reading of main and leisure battery voltage, and inside and outside temperature in the van. I spent ages on researching and found some bits here and there that might help, but nothing to do the whoe job, and nothing really satisfactory, until

This Instructable brought to you by the kind folks a Rachel’s Electronics Visit www.rachelselectronics.com for cool electronics kits and breadouts! This hobby servo hack will add shaft position feedback by tapping into the servo’s own internal potentiometer. The only parts that need are wire and a little bit of solder, making this hack practically free.

In this Arduino UNO tutorial, we are going to use a Light Dependent Resistor (LDR) to create a simple childrens bedroom nightlight which turns on automatically when it gets dark and turns off when it gets light. An LDR’s resistance changes depending upon the amount of light hitting the sensor. For the LDR we are

This mod uses a custom designed encoder on one of the wheels to track where the longboard is on the ground and light up the LEDs so that the light pattern remains stationary on the ground as the board moves over it. To make doing this instructable as easy to understand as possible, you will

Introduction This page describes how to reflow solder surface mount printed circuits using a cheap toaster oven. It owes a great deal to Nophead’s Cooking with Hydraraptor blog post. The picture shows Sally Bowyer (Director, RepRapPro Ltd) preparing components for soldering in the oven. For more instructions on this see the video at the bottom

This was my very first arduino project. Its great for beginners. Fade the color or the lights my moving your hands near it. It fades from a pretty purple blue to a firey red-orange. Its was SUPER easy to build, not to hard to write the code, and its really impresses people! I gave it
