Theremin is an early electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after the Russian inventor, Léon Theremin, who patented the device in 1928. A typical theremin musical instrument is shown in Fig. 1. This article explains how you can build an optical theremin using an Arduino Uno board and some readily available components. Etherwave ...

This article describes a temperature monitoring system on an Android smartphone. Temperature is sensed by a temperature sensor installed in the circuit and is sent over Bluetooth to the smartphone. An Android application is used in the smartphone to display temperature data. The system provides easy monitoring of process data on a smartphone. You can connect the smartphone wirelessly with the system and mon ...

In this tutorial, I’ll explain how to set up an LCD on an Arduino and show you all the different ways you can program it. I’ll show you how to print text, scroll text, make custom characters, blink text, and position text. They’re great for any project that outputs data, and they can make your project a lot more interesting and interactive. The display I’m using is a 16×2 LCD displa ...

Arduino enthusiasts and makers searching for a new project to keep them busy this weekend may be interested in a new DIY Arduino Nano multimeter created by YouTuber Electronoobs. Using a small OLED screen in combination with the Arduino Nano together with a couple of buttons and 16-bit ADC for precise measurements the multimeter has been finished within simple 3D printed casing. Power to the multimeter is p ...

For the long series of articles documenting My Journey into the Cloud I used two small evaluation boards, equipped with an ESP32 32-bit controller, an antenna and a micro USB socket (the latter also serves for power supply input and provides a path for uploading programs). For newcomers, the controller can be programmed using the intuitive Arduino IDE, because the board manufacturer Espressif has provided a ...
