How to Make a Water Level Indicator with Arduino 6 11

Knowing the amount of water in an overhead tank can be one tedious task. Usually, you’ll end up climbing up the stairs to the tank and checking the level manually or you’ll you hear the water overflowing from the top. But these days electronic water level indicators are available to fix this problem, but they often come with a hefty price tag and are usually difficult to install. Most of the available syste ...

How to make a Smart Cane for the Visually Impaired with Arduino

I wanted to make something for them to help the visually impaired become independent, so I created an open source Arduino project for a Smart Cane. This Arduino smart cane can assist with walking alone in new environments by taking inputs through an obstacle sensor (ultrasonic sensor) and providing feedback to the person through haptics (vibration motor). Check out the video below for the demo and working. ...

Arduino CNC Shield – 100% GRBL Compatable

Do it yourself CNC projects are popping up everywhere and we decided that we wanted to contribute to the growth. Here are a few of our design goals: Modular Design – We wanted to do more than just keep cost down. We wanted things to be reusable and up-gradable. (Arduino , Individual Stepper Motor Drivers and more…) Compact Design – Squeezing a 4 axis design into a board the same size and Arduino Uno. Openso ...

DIY Arduino Tutorial: How to Automate a Lamp for Ceremonial Inaugurations

“Knowledge removes ignorance, just as light removes darkness”, as it is wisely said. In India, the ancient tradition of lighting oil lamps has a special significance. Almost all auspicious ceremonies are commenced by lighting a lamp. Hence came the idea to merge our traditional culture with the digital world using this DIY Arduino Lamp. We did this by lighting a series of LEDs wirelessly on an oil lamp by u ...

DIY Arduino Tutorial: How to Automate Your Curtains

This Arduino Curtain Automation project will let you automate your curtain blinds using just an Arduino and a stepper motor. I just moved to America pursuing my higher studies. Because my dorm is very dark, I wanted to brighten up my room when I wanted to. Since I would be there for only for a month, I couldn’t make anything too complicated. So I decided to make myself this DIY Arduino Curtain Automation sy ...

Create a Christmas Light Show with Arduino

The Christmas light show with Arduino is a project that controls a number of lights according to a song in sync with the music. It can be used to control stage lights and fog machines (that don’t have DMX) with a computer to achieve wonderful synchronization for performances on stage, which is not always possible with manual lighting control consoles. During last year’s holidays, I was watching videos of Ch ...

Arduino Servo Catapult: DIY Catapult using Arduino

Use an Arduino and a servo to shoot food to your cat! (Also works with other animals). Check out the video below to see how this Arduino Servo Catapult works. While maybe not the most practical application, this project will teach you the basics of servo motors and analog inputs, which can be implemented into more practical projects, like these: Give Your Camera Motion Tracking With Arduino Make a Line Foll ...

Measure Capacitance with Arduino

This tutorial provides a guide on how to set up an Arduino to measure the capacitance of a capacitor. This can be useful if the capacitor is unlabeled or if it is self-built. Capacitance is an object's ability to store an electric charge. Reasonably, this object is referred to as a capacitor. A capacitor that stores this charge in an electric field between two conductive plates is known as a parallel plate ...

DIY Soil Testing with Arduino and FC-28 Moisture Sensor

In this article, we are going to interface an FC-28 Soil moisture sensor with an Arduino. This sensor measures the volumetric content of water in soil and gives us the moisture level. The sensor gives us both analog and digital output, so it can be used in both analog and digital mode. We are going to connect it in both modes in this article. How Does it Work? The soil moisture sensor consists of two probes ...

Arduino Wheelchair Project: Motorized Controller Mount

This was an Arduino wheelchair project we developed for Principles and Practices of Assistive Technology (PPAT) in Fall 2016 at MIT. We made an Arduino-based motorized wheelchair controller mount for our client, Lisa. She lives at the Boston Home, a center for people with progressive neurological diseases, and has Multiple Sclerosis. With her old controller mount, she would often bump into sinks and tables ...
