USB Interface Board Tutorial Using PIC18F4550

USB Interface Board using pic18f4550 microcontroller tutorial

This tutorial project shows the Step 1, Making of the Hardware for a computer USB Interface through pic18f4550 Microcontroller (USB INTERFACE BOARD) which allows to control some device like led, motors and other devices with computer through a USB Interface hardware that we are going to make with easy steps. pic18f4550 usb interface project is Human Interface Device (HID).

First Step


BOOT LOAD THE PIC18F4550 - FIRMWARE UPDATING | SETTING THE PIC18F4550 IN RD/WR ( BOOT LOAD ) MODE FOR BOOT-LOADING new code into the USB INTERFACE BOARD, it can be done with a bootloader Software

Identify Anode Cathode of Led ( Light Emitting Diode )

How to Identify the polarity (cathode/anode) of a LED , How to identity the -ve and +ve (cathode anode)polarity of a LED without using multimeter.LED's or Light Emitting Diode's don’t come with any labeling on it to identify Cathode(-ve,GND) or Anode(+ve).So for identification , led’s comes with a unique way to identify its terminals as Anode or Cathode.
