DC Motor featuring 4Duino-24

In this project, we will learn how to control the speed and direction of a DC motor via I/O ports with PWM output capability, a L293D quad half-h drivers IC and 4D Workshop widgets. In its simplest form, a DC motor has two wires which is connected to a power supply. Depend on whichever way current flows in the DC motor, this will determine the direction in which the motor will spin. Motors are often used in ...

How To Select a Capacitor

When I was working on the capacitors section for the next version of Common Parts Library, I realized that it would be helpful to explain why one might pick one capacitor type over another. This information is important because there are a lot of factors (temperature characteristics, package, etc.) which might make a type of capacitor (electrolytic or ceramic) better than others for your project. In this bl ...

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 ...

DJ Mixer featuring 4Duino-24

The 4Duino DJ Mixer is a fun and interactive project similar to a keyboard MIDI Controller that has the ability to play sample beats and songs. Before, DJ and music artist needs to use computers, recording and playback devices before they can mix and play their own customized music. But using this project, the user can utilize the 4Duino LCD screens and the 4D SOMO-II music module. The 4Duino will serve as ...

Arduino Remote Control Tutorial

In this tutorial I am going to show you exactly how to make an Arduino remote control. You can use this project to combine functions from different remote controls and make your super-awesome dream remote control! If you are not familiar with Arduino, check out What is Arduino and where to start? A remote control sends out an infrared (IR) code when you push a button. The gadget you point the remote control ...

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 ...
