Figure 1: USB Communication Circuit Diagram The HID device class code is “0x03, this class is used for devices operated by human, devices like keyboard, mouse, joystick and so forth. The advantage of HID devices is that, they don’t require to install drivers, in most modern operating systems, the device will be detected without any […]
This project is a spin-off of another project I am working on and since there is a Remote Control 2017 contest on Instructables I thought I post this project. So if you like this project, please vote for it. Thanks. As you may know, I am a big fan of the Microchip 8-bit PIC controllers, […]
Source Code for PIC16F84 and CD4511 decoder Also, there is an updated version with NPN drivers replacing the 4511 and many new features by Brendon Archibald [websales optusnet.com.au] DARKROOM TIMER The purpose of this project is to present a device that is useful and at the same time demonstrate to the beginner many features […]
Peripheral Interface controller (PIC) family is one of the most powerful advanced microcontroller which is developed by the microchip technology with Harvard architecture, i.e., it has a minimum set of instructions. The PIC microcontroller projects are programmed with the embedded C programming language. PIC devices consist of powerful featured controller with an internal RAM, EEPROM, […]
The circuit diagram is quite simple. I have powered my circuit with 4 AA batteries that gives 6 V supply. A diode is used in series to drop the voltage down to 5.4 V as the operating voltage for the PIC microcontroller should be below 5.5 V. Besides, the diode also provides the protection to […]
Parallel interfacing LCD with MCU at least need 6 I/O pins (4 bit mode) and maximun can up to 11 I/O pins (8 bit mode). The I/O pin can be cut down to 3 pin by serial iterfacing using shift register. They were few shift register can be used such as 74HC164, 74HC595, CD4094 and […]
“Robot-Car: Design Fused with Obstacle Avoidance Technology” Recently, there is an intensive research undertaken in the field of intelligence robotics and autonomous mobile robot applications. Through the this project we wanted to explore this field by building a robot car that can potentially avoid the obstacles. This is a user controlled robot car that has […]
This is a good Electronic project report on Speed Control of DC Motor using Microcontroller by using PWM. In this system, a micro controller is interfaced with a LCD, Keypad and DC motor driver. The Micro controller is used for controlling the DC motor by producing the PWM pulses. These pulse widths are produced according […]
Here i am going to explain you a simple Password based circuit Breaker Project using PIC Microcontroller. This project is much similar to my previous one, “Password Based Door Locking System”. Circuit breakers are electromechanical devices used in the power system to connect or disconnect the power flow at the generator, substation, or load location. […]
