Hello, fellow Makers! In this instructable, I will be discussing my newest and most versatile tool for edcuation: the E.M.F. Meter. This instructable will be covering a lot of steps involving Arduino and Raspberry Pi software. Although resources will be provided, please make sure you have some familiarity with these softwares before tackling this project.

Liquids or other objects appear colored because theyreflect or transmit certain colors and in turn swallow (absorb) others. With a so-called photometer, those colors (wavelengths) can be determined, which are absorbed by liquids. The basic principle is simple: with a LED of a certain color you first shine through a cuvette filled with water or

That whole project started a while back with an hackaday article from 2014 in which [Johngineer] build the ‘ChronodeVFD’, a wristwatch made from an old soviet vacuum fluorescent display. It kind of triggered the ‘shut up and take my money’ reflex in me, but as it wasn’t for sale and didn’t have any design details available I

What if I told you that you could build a display out of shoe laces!? Well that is exactly what I’ve done! Building your own seven segment display is nothing new, it’s a very common Arduino project, but I had an idea for this one so I said I’d give it a go, and I

n this tutorial we are going to show you how to setup your own temperature and humidity sensor. We are going to use a DHT22 unit, which is a low-cost digital output relative humidity and temperature sensor. The device includes a capacative humidity sensor and a thermistor to measure air temperature DHT22 Specifications Temperature Range: -40

In this tutorial we’re going to make an internet connected smart lamp. This will go deep into internet of things and opens up a world of home automation! The lamp is WiFi connected and built to have an open message protocol. This means you can select whatever control mode you want! It can be controlled

This instructable explains how to motorize a time lapse rail using a step motor driven by an Arduino. We will mainly focus on the Motion Controller that drives the step motor assuming you already have a rail you want to motorize. For example when dismantling a machine I found two rails that I could convert into time

Hi guys, my name is Pedro Castelani and I’m bringing you my first instructable: building a two way radio with arduino for, well, whatever you need it for. In this project, we will make two seperate circuits which will act as both reciever and transmitter. The most important components are two arduino boards (all of
