Assistance for Visually Impaired featuring 4Duino-24

Blind Assistance is a project designed to help visually impaired people detecting obstacles in their way. It uses 4Duino, three ultrasonic sensors, one vibration motor and an LED. These components are attached to a walking stick. Blind Assistance alarms the user if there’s an obstacle in his way. These obstacles are detected using an Ultrasonic Sensor. It is able to measure distances from 2cm to 400cm. Ultr ...

HTML5 Circuit Simulator

This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It's very helpful for experimentation and visualization. Best of all, thanks to the power of HTML5, no plug-ins are required! The original implementation, in Java, belongs to Paul Falstad who kindly gave his permission for me to build this port. How to use this When the simulator starts up you will se ...

WiFi Temperature Sensor featuring 4Duino-24

In this project we will quickly create a ‘temperature monitor’ that measures the ambient temperature of a room or an outdoor space. The temperature is measured by TMP35 temperature sensor and is displayed on the 4Duino screen. The data is also sent to Thingspeak IoT platform which enables data logging over a period of time. How it works Components 4Duino TMP 35 Temperature sensor Bread Board Jumper cables µ ...

Dead Simple Ultrasonic Data Communication

Some of the best hacks are the ones which seem perfectly obvious in hindsight; a solution to the problem that’s so elegant, you wonder how it never occurred to you before. Of course we also love the hacks that are so complex your eyes start to water, but it’s nice to have a balance. This one, sent in by [Eduardo Zola] is definitely in the former group. In the video after the break, [Eduardo] demonstrates hi ...

BeagleBone Logic Analyzer

Since I started this adventure in hardware I have wanted to get an logic analyzer. I have an older but good oscilloscope that only goes so far when it comes to digital logic signals. I could go for the Saleae, but if I am going to do that I would rather sprint for the higher end model which is an easy $400+. In the mean time I was on a quest to find a low cost option. Upon my travels of the interwebs I foun ...
