This Instructable shows the steps I took to build my own open source theremin (Open Theremin) when there was none available to buy online. The lovely thing about open source is that the plans are freely available to make and modify. A theremin is an electronic musical instrument that you play waving your hands in

Introduction There are probably over one-hundred Arduino based plotting machines on the internet with instructions available on how to make them. What makes this one unique (as far as I know), is the inbuilt camera and screen. Other plotters must be connected to a computer. This one works completely independently. The 20fps video shown on

In Today’s Tutorial, we will learn how to make our plant talk using Arduino nano with the MP3 player module. Basically, we will connect 3 sensors to the Arduino module: LDR Sensor. Capacitive Moisture sensor. DHT22 Temperature and humidity sensor. We will read the sensors values in Arduino and define the limits for each sensor

You probably know Tinkercad for the beginner friendly 3D CAD program, but it also includes a circuit + Arduino simulator that runs in your web browser! I’ve used Tinkercad for both in-person and online college-level classes and for introductory makerspace workshops. In this Instructable I’ll not only show you how to teach your own intro circuits/Arduino class using

Height is a major concern in public places. Kids affected more in public places due to height problem. The problem places due to height concerns are 1) First place is school from kg kids to High school kids, so lot of height variation so using wash basin, now a days while enter using hand sanitizer.

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

Introduction / Why this project In 2016 I build my first fish feeder, see Fish Feeder 1. The feeder worked fine for more then half a year. After that period the servos were worn out, causing the program to halt, without sending an error-mail. Oops. I didn’t had the time to correct this fault, because the aquarium
