H-Bridge Microchip PIC Microcontroller PWM Motor Controller
Monday January 26, 2009 by rwb, under Microcontroller.
One of the advantages using the Microchip PIC microcontroller Pulse Width Modulation or PWM for short is; this PWM peripheral circuit is designed to control the DC motor using the full bridge mode PWM feature. The PWM peripheral works by supplying the correct signal to the H-Bridge DC motor circuit such as speed controlling and changing the DC motor direction. Read more »

PIC Analog to Digital Converter C Programming
Sunday January 18, 2009 by rwb, under Microcontroller.
The PIC16F690 microcontroller is one of Microchip midrange 8-bit microcontroller that has a build in 10-bit resolution of Analog to Digital Converter (ADC) peripheral. The ADC is one of the important features that enable us to digitize our analog world. Usually we use the electronic sensor to convert the analog value to the voltage level value. Read more »

AVR Twinkle Twinkle Using PWM Project
Saturday January 10, 2009 by rwb, under Microcontroller.
Would be interesting if we could make our microcontroller to sing for us not just beeping or blinking; this project is all about using the powerful AVR ATmega168 16-bit PWM feature to produce accurate musical notes such as playing the child’s favorite Twinkle-Twinkle Little Star song or we could say beeping with style.

AVR LCD Thermometer Using ADC and PWM Project
Saturday January 03, 2009 by rwb, under Microcontroller.
Sometimes we need our microcontroller to interact with more human readable information. It will be better for us if we could make it display the words not just blinking the LED. Today most modern gadget such as mobile phone and PDA, use LCD (Liquid Crystal Display) for interacting with us. In this project we will learn how to use the 2×16 LCD for displaying the room’s temperature. Read more »

Controlling DC motor with AVR ATtiny13 PWM and ADC Project
Saturday December 27, 2008 by rwb, under Microcontroller.
It’s interesting to explore what we can do with this tiny 8 pins; 8-bit microcontroller. The ATtiny13 is the smallest and cheapest Atmel AVR 8-bit microcontroller families but yet, it’s loaded with sophisticated peripherals such as two 8-bit PWM channels and 4 channels 10-bit ADC. Read more »

Using Transistor as a Switch
Tuesday December 23, 2008 by rwb, under Electronics.
Most of microcontrollers work within 5 volt environment and the I/O port can only handle current up to 20mA; therefore if we want to attach the microcontroller’s I/O port to different voltage level circuit or to drive devices with more than 20mA; we need to use the interface circuit. One of the popular method is to use the Bipolar Junction Transistor (BJT) or we just called it transistor in this tutorial. Read more »
