Control any MIDI parameter value of your DAW through hand movements. The first controller was made using the knobs of a potentiometer, however the functionality of the knob is only to send values from 0-127 and this can be done by any means, so we thought of using the ultrasonic sensor. This design has been…
If you play sports in the gym or have a flat bench at home, this project could be useful for you. It is a counter that shows the movements made with the balance wheel on a display and, with each increment, a robotic voice repeats the number through a speaker. The project is based on…
In this project we will see how to build a smart bin. The system detects if the bin is already full and opens automatically when someone approaches. What gives it an edge over other smart garbage cans on the market is that it uses a touch screen display that allows the user to interact and…
Created by Mr Innovative, this Arduino based mini radar is capable of detecting objects placed in its line of sight. The 3D-printed console features a small SG90 servo to pan the sensor over a space, picking up obstacles in its path. The readings are then transmitted to an Arduino Nano, which displays object info on a…
“The device features an ultrasonic sensor for measuring the distance to the nearest object, an accelerometer for measuring the angle with respect to the ground, an LCD display for showing the results and a custom designed PCB on which all components are connected.” Combining an ultrasonic sensor for range measurement and an accelerometer for measuring…
If you need to monitor the fluid level in a large diameter well, a tank, or an open container, for only €70 you can build your own Ultrasonic fluid level monitoring system. One day, my brother and I talked about how our grandfather used to measure the water level manually in order to keep track…
Fans of Valve’s innovative and unique video game series Portal should check out a recent Instructables page published by a user called Stephen Gioiosa. As part of a maker course at the University of Florida, the Portal enthusiast 3D printed a replica of Aperture Science sentry turret, one of the game’s iconic turrets. The results he achieved are pretty impressive for…
Recently, low-cost microcontrollers like the Arduino have opened new doors for makers looking to do fun and interesting things with their vehicles. If you’ve ever had to park your car in a small garage or cramped space, you probably understand the frustration of not knowing how much room to leave behind and in front of your car….
