In a previous tutorial we have seen how to run two stepper motors synchronously from a given start position to a defined destination using an Arduino and a very simple “user interface”. That user interface was restricted to some microswitches and LEDs, both installed on a breadboard. As promised, this new instructable shows how to add a …
When you see something made from metal that seems like it would be impossible to manufacture, chances are good it was made with some variety of electrical discharge machining. EDM is the method of choice for hard-to-machine metals, high aspect ratio hole drilling, and precise surface finishes that let mating parts slip together with almost …
This Power Timer is based on the timer presented at: https://www.instructables.com/id/Timer-With-Arduin… A power supply module and an SSR (solid state relay) were attached to it. Power loads of up to 1KW can be operated and with minimal changes the load power can be increased. The choice of timer duration or program number is set from …
This ECG (Electrocardiogram) unit has an integrated display. The display can show individual heart beats in a large format, the train of heart beats in a small format and a Poincaré plot. It is battery powered and can be worn round your neck on a lanyard. It is built from an AD8232 module (£7 with leads), an …
Multimeters are suitable for many purposes. But usually, they only measure one value at a time. If we deal with power measurements, we need two multimeters, one for voltage and the second for Ampere. And if we want to measure efficiency, we need four multimeters. Here we will build small and inexpensive meters to do …
For this project, I wanted to create a winch that would be functional for use in a show in a theatre. Often, we have to fly in and out small objects, like chandeliers. This unit would be ideal for raising and lowering small objects in spaces that did not have a fly system, or for …
I think these RGB LED Matrix displays are one of best displays you can get for your Arduino projects, they are incredibly bright and vivid and are actually pretty easy to use too! They can be used for displaying text, images or a combination of both Check out some of the examples of what can …
Please vote for this in the fitness challenge instead of a Fitbit or a smartwatch, you can build an Arduino powered fitness tracker for only $15! It tracks the pumping motion of your arms while running and uses an accelerometer to detect this. It is powered by an Arduino Nano and displays the unit that …

The Internet of Things (IoT) is creating many new exciting application opportunities to create smart environments where sensors monitor for changes so that the appropriate actions can be taken. The fastest growing examples of this are HVAC (Heating Ventilation and Air Conditioning), IAQ (Indoor Air Quality), smart homes and smart offices where a network of sensors monitors temperature and …
