This document outlines a project for designing a Bluetooth controlled robocar using the PIC16F887 microcontroller. The project involves using components like the HC-05 Bluetooth module and L293D motor driver for control and communication. It discusses the functionalities and specifications of these components, as well as the implementation of the system through an Android interface.
Bluetooth Controlled Robocar Using PIC 16f887
- 1. Embedded System Sessional Project BLUETOOTH CONTROLLED ROBOCAR USING PIC 16F887
- 2. Introduction: This project aims at designing a robocar can be controlled using Bluetooth. Bluetooth controlled car is a robot which is built using PIC16f887 Microcontroller in which serial communication is done via Bluetooth and programming is done in embedded C language.
- 4. Building Blocks: PIC16F887 Microcontroller HC-05 Bluetoot h module L293D Motor Driver Android phone
- 5. PIC16f887 Microcontroller: High performance and low power microcontroller RISC Architecture 3 Independent Timer/counter & Watchdog Timer 8 KB RAM and 256 Bytes EEPROM Enhanced Serial USART Module Programmer friendly
- 7. What is Bluetooth? RF based Wireless Technology Low cost , short range less power consuming Speed less than 1 Mbps!
- 8. HC-05 Bluetooth Module: The HC-05 small size Bluetooth TTL transceiver module are designed for serial communication (SPP - serial port profile). It allows your target device to both send or receive TTL data via Bluetooth technology without connecting a serial cable to your computer. It has Coverage up to 30 ft / 10 m with Built in antenna. It has Power input: +3.3VDC (bluetooth module).
- 9. PUSH-PULL four Channel Driver with Diodes Designed to accept standard DTL or TTL logic levels and drive inductive loads and switching power transistors Suitable for use in switching applications at frequencies up to 5KHz It is assembled in a 16 lead plastic package which has 4 centre pins connected together and used for heat sinking. L293D MOTOR DRIVER
- 11. What Is Android: Is an operating system based on Linux Kernel It is designed primarily for touch screen mobile like smart phones and tablet computers User interface of android is based on Direct Manipulation Internal hardware such as accelerometers, gyroscopes and proximit y sensors are used by some applications to respond to additional user actions
Editor's Notes
- #10: DTL means Diode Transistor Logic
- #12: direct manipulation is a human–computer interaction style which involves continuous representation of objects of interest and rapid, reversible, and incremental actions and feedback.[1] As opposed to other interaction styles, for example, a command language, the intention of direct manipulation is to allow a user to manipulate objects presented to them, using actions that correspond at least loosely to the physical world. An example of direct-manipulation is resizing a graphical shape, such as a rectangle, by dragging its corners or edges with a mouse. The user interface, in the industrial design field of human–machine interaction, is the space where interaction between humans and machines occurs.
