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 […]

Things used in this project Hardware components Arduino MKR1000 × 1 Arduino UNO & Genuino UNO × 1 Dynamixel Servo MX-64T × 2 Dynamixel Servo AX-18A × 2 Hitec HS-225BB Servo × 2 BTS7960B Driver […]
Controlling a robotic arm to pick up and drop objects is difficult enough, without IoT it would be near impossible to do this remotely. Things used in this project Hardware components Arduino MKR1000 × 1 Software apps and online services MATLAB Arduino IDE Hand tools and fabrication machines Laser cutter (generic) Story Introduction I really […]
Motor starter reduces the load, torque and current surge of a motor during startup. On starting, the motor takes more than five times the normal running current. This overheats the motor’s armature winding and creates a sudden voltage dip in the power supply, which can be avoided by using a motor starter. There are many […]
