PIC18 Pulse Width Modulation (PWM) DC Motor Speed Controller with the RPM Counter Project
Wednesday December 09, 2009 by rwb, under Microcontroller.
Equipped with sophisticated Enhanced Capture/Compare/PWM (ECCP) peripheral the Microchip PIC18F14K50 microcontroller could produce up to four PWM channels output. The enhanced PWM (Pulse Width Modulation) mode in ECCP peripheral is capable to drive the full bridge DC Motor circuit directly both in forward or reverse direction. It also could generate single PWM output on the selectable PIC18F14K50 pins when it configured in pulse steering mode. Read more »

PIC18 Microcontroller Analog to Digital Converter with Microchip C18 Compiler
Sunday November 08, 2009 by rwb, under Microcontroller.
The Microchip PIC18 Microcontroller family is the Microchip highest performance 8-bit class microcontroller. Powered by advanced RISC CPU, this PIC18 microcontroller family could deliver up to 16 MIPS computing power compared to the other Microchip 8-bit microcontroller family such as PIC10, PIC12 and PIC16 which only could deliver up to 5 MIPS. The PIC18 microcontroller architecture is optimized to be programmed in C language and supporting many advance industrial standard interface peripherals such as I2C, SPI, UART, USB, CAN, Ethernet, LCD and Touch Screen; this make the PIC18 microcontroller family become a popular choice to the new 8-bit embedded system design.

Introduction to the Embedded System with PICAXE Microcontroller
Saturday October 17, 2009 by rwb, under Microcontroller.
These days we are living and surrounding by many tiny computers called embedded products. Unlike the general purpose desktop computer that we use for browsing or typing our email, this tiny computer is designed to do only a limited specific task. We could easily found this embedded product just about anywhere such as home appliance (e.g. washing machine, refrigerator, microwave oven, TV/DVD), personal gadget (e.g. cell phone, MP3 players, digital camera), car (e.g. anti lock brake system, GPS navigation, alarm) and many more. The tremendous use of the embedded products in our daily life make the embedded system become one of the most important and interest subject to be learned. Read more »

Transforming your AVR Microcontroller to the I2C or TWI Slave I/O Expander Project
Sunday September 27, 2009 by rwb, under Microcontroller.
The I2C bus (read as I squared C) is one of the most important embedded system serial bus interface first introduced by Philips in 1980; using just two lines called SCL (serial clock) and SDA (serial data) respectively make the I2C bus is a perfect choice to provide additional I/O capabilities to your microcontroller project without changing your microcontroller type and design in order to increase the I/O port pins.

Build Your Own Microcontroller Based PID Control Line Follower Robot (LFR) – Second Part
Sunday August 30, 2009 by rwb, under Robotics.
One of the interesting parts in building the Line Follower Robot is; you could start it with a very simple version by using just two transistors with the LED and LDR for sensor (Build Your Own Transistor Based Mobile Line Follower Robot - First Part) and enhance it to the programmable version that use microcontroller as the brain for controlling the robot. The reason of using the microcontroller for the Line Follower Robot is we need to make more robust, reliable and flexible robot which you could not have it from the discrete electronics component robot without changing most of the electronic circuit design.

Some Cool Electronics Stuff from Your Discarded DVD Player
Monday July 20, 2009 by rwb, under Yet Another Tips.
Today you could easily find a decent quality DVD player for under USD 50; therefore many people just throw it away when it’s broken and just buy a new one instead of repairing it. But as the microcontroller and electronics hobbyist you would be amazed of how these junks could be become your home’s lab valuable asset and these electronics stuff perhaps worth almost USD 50 if you buy it one by one.

Build Your Own Transistor Based Mobile Line Follower Robot (LFR) – First Part
Saturday July 11, 2009 by rwb, under Robotics.
The mobile line follower robot is a type of mobile robot with only has one specific task which is to follow the line made with black tape over the white background or vise verse. The LFR perhaps is one of the most popular robot build by the roboticists. What makes this LFR is so popular, I think because of its simplicity and yet it could be used as the teaching tools of how we could implement the industrial standard control system such as the PID (Proportional Integral Deferential) control system on this robot. Another factor probably is the increase of the LFR annual tournament conducted in many countries. Read more »
