This project demonstrates a computer control interface using a USB Board. (USB INTERFACE PROJECT). This tutorial will show you a simple way to control some device like led, motors and other devices with computer through a USB Board. The traditional way to control devices from a computer was to use a parallel printer port which is much more easy to

implement than that of a USB PROJECT, but the only limitation with parallel printer port is that the latest computer does not comes with parallel printer port. So you can use this project as an alternative to a parallel port interface. pic18f4550 usb interface project is Human Interface Device (HID). This tutorial is not so difficult for a experienced person however I am also posting a step by step procedure for beginners. If you are an experienced person with microcontroller then all you need to do is to make the USB board Circuit and then burn the firmware into the microcontroller, with a microcontroller programmer and then install the drivers on your system, and finally launch the application after connecting the main board to the computer with a USB PORT. -Experienced personal can go to end of Interface Board link and can download everything at the end of that page. Beginners can follow this page and continue on for full description. - This project allows you to control some device with your computer on clicks of few buttons on a small application written in C# which communicates through the pic18f4550 microcontroller. But creating this board can be difficult for beginners and easy for experienced persons. In traditional parallel printer port interface project all you have to do is to connect few led`s across you parallel port (printer port) and code an application in Visual Basic or C# and you are done. But when it...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
