RS485 – ARDUINO AND INDUSTRIAL DISTANCE SENSOR

I have in my hand a distance laser sensor with high precision and speed. It is used in industrial environments for object positioning or detection applications. According to technical documents, I found it can communicate with other devices via RS485. I spent the weekend to learn it and find ways to communicate with cheap CPU - Arduino. And finally, I succeeded in reading data from it and displaying the dis ...

Sunlight Detection Alarm

Most technology Instructables are fun to construct, and often easy to build. This is one that shares those features, but also solves a practical problem we had. To prevent fading of furniture, carpet, and the wood flooring in our foyer, my spouse and I installed one-way blackout shades. However, after installation and use, a problem arose. The air in the foyer began to have a slightly “musty” odor as no sun ...

How to Use Water Flow Sensor – Arduino Tutorial

In this tutorial you will learn how to use one water flow sensor with an Arduino board. The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This type of sensor can be found on different diamet ...

DIY Muscle Sensor / EMG Circuit for a Microcontroller

Measuring muscle activation via electric potential, referred to as electromyography (EMG) , has traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems. Yet, EMG systems remain ...

DIY Standalone Weather Station Powered by Arduino

Hello Makers out there Again this is not a Step by step Instructable . Like always i forgot to take take snaps since the inception of this project.The idea of Building a community weather station using Open hardware Kicked a long back. We people from a local DIY community build this weather station. In our country we don't give importance to weather data apart from the days where we have heavy rain or cyclo ...

Drumming MIDI Glove Using Arduino and Light Sensors

I will describe a fun and easy way to build your own sound expression MIDI enabled glove without expending lot's of money on MIDI Interfaces or expensive sensors. Feel free to contact me directly by mail if you like it or have suggestions.  This project was inspired by other do it yourself projects using Piezo (buzzer) as input sensors but they are too big and need filtering for precise velocity readin ...

Arduino-Using Shift Registers With Ultrasonic Sensors

The HC-SR04 Ultrasonic range sensing module is great for sensing distances that can be used as an input for your Arduino projects, but using multiple (more than two) can quickly cost you a lot of pins. This basic Instructable gives you the code and basic instructions to use the 74HC595 8 bit series to parallel shift register so you can connect up to 8 HC-SR04 modules (16 IO pins) while using only 4 Arduino ...

Synesthesia Mask

https://youtu.be/9vLSuLL9xLA Inspiration What if I told you that 2+2=Red!?!? What!?! I know this sounds crazy but for people with synesthesia this might be their reality. Synesthesia is defined as "the production of a sense impression relating to one sense or part of the body by stimulation of another sense or part of the body." This is a complicated way of saying that people with synesthesia have blended s ...

B-SENSOR: DIY PRESSURE CUSHION

This project examines how interface pressure is a key risk factor in the development of pressure ulcers. Visual feedback of continuous interface pressure between the body and support surface could inform clinicians on repositioning strategies and play a key role in an overall strategy for the prevention and management of pressure ulcers. eTextiles are made using techniques and materials that make it so elec ...

Image Processing Based Fire Detection & Extinguisher System Using Arduino

This is an image processing based fire detection and extinguisher system using Arduino. It is basically the system is divided into two parts: Fire detection 2. Fire alert and extinguisher In the first part, fire detects using image processing. Here in this project I’m using open CV and python for fire detection. I created a HAAR Cascade Classifier for fire detection using Open CV. It has trainer and detecto ...
