Have you ever come across your mind that you would like to develop a Dual Motor Driver with Arduino by using a SN7554410NE Quad Half H-Bridge?

Well, maybe some of you here didn’t get in touch with H-Bridge before. In this case, you must know that H-Bridge is an electronic circuit that enables a voltage to be applied across a load in either direction. Usually, H-bridge is often used robotics and other applications to allow DC motors to run forwards and backwards. In most of the time, H-bridges are available as integrated circuits.

For today’s project, you’re going to use a SN754410NE Quad Half H-Bridge to control two 12 volt DC motors. Those electronic components that you’re needed are: Read more »

Nowadays, the computers are one of the most common household devices and it’s already become a familiar household appliance at every family.

Some of us were probably known computer pretty well, but how about the microcomputers? Have you ever wondered, what is the main purpose of the microcomputers? To be honest, a microcomputer is a computer with a microprocessor, as its central processing unit.

In this case, there is another general characteristic of the computers, where they occupy physically small amounts of space when compared to mainframe and microcomputers.

The term “Microcomputer” was came into popular, after the introduction of the minicomputer by Isaac Asimov in July 1965. In that moment, the microcomputer replaced the many separate components that made up the minicomputer’s CPU with a single integrated microprocessor chip!

Today’s project is about the Vessel Microcomputer Network. Frankly, there are many applications for small networks of microcomputers. The example includes home automation, trucks and factory floors.

The reason why Vessel Microcomputer Network or commonly known as “VuN”, which is a general purpose, low cost system for connecting multiple micros and transferring data among them!

VuN can be used to perform the following tasks:

• Collect and display information about fuel and water levels,

• Engine information,

• GPS position

• Track information

Furthermore, VuN can be operated with only battery power and it’s definitely a green gadget!

The word, “Kohtauskone” might sound a little bit strange, but it’s a very interesting project that you should keep your eyes on it.

Kohtauskone is a small project that can be used to control strobe light through DMX protocol. Basically, it’s built on top of a Pro Mini Arduino with simple DMX driver circuit.

For your information, it has a button to kick the action, rotating switch for choosing different presents and one switch for future expansion. Did you know that you could control any DMX device with this hardware, especially the strobe light?

Since the Pro Mini is quite tiny, you have to build the whole thing and fix it into the smaller box. Honestly, most of the people didn’t know what is the point of using a non USB version of Arduino board. In this situation, it would be the perfect example of the project, where you won’t have to fit Duemilanove inside the tiny box.

The very first step is to build a DMX driver. You must use the instruction at Arduino Playground to develop the circuit on tiny piece of circuit board. The circuit gets power through Arduino and then outputs ‘+’ and ‘-’data lines to XLR jack.

Ok, it won’t be a new project for some of you here, especially the LED Matrix. Maybe you’ve involved with LED Matrix more than once, twice or several times, but it’s still a fun to develop a brand new LED Matrix in different method.

For this project, you’ll have to make an LED matrix display in 16×24 Green SMD LED matrix. Beside that, you must apply a driver for it. In this case, you can use shift registers to sink the columns and a line driver of some sort to source the rows.

To be honest, the matrix is a lot bigger, as it used eight IO lines to drive each row. Since the matrix has sixteen rows, you can use an ATmega168 and a 4:16 de-multiplexer to control all sixteen rows with only four IO pins. Read more »
