How to work with inbuilt ADC Module of PIC18F4550

A microcontroller, a digital device, can read, execute and transmit only digital signals. On the contrary, the outputs of the most of the transducers are analog in nature. Thus it is hard to interface these transducers directly with controllers. Analog-to-digital convertor (ADC) ICs are one way to make the analog input compatible with the microcontroller.

Hee Haw Sound

This experiment creates a Hee Haw sound for an alarm. The diagram shows the number of cycles for the HEE and the time taken for each cycle, equates to a certain length of time. The frequency of the HAW is lower and the number of cycles must be worked out so that the time for the

Your first PICMicro Project using PIC16F84

After doing two weeks on LCDs, I thought I’d spend a few weeks focusing on the number one question that I get asked; “How do I start working with the Microchip PICMicro?” The question is asked from a variety of perspectives and goals, ranging from somebody that just wants to become casually familiar with the

PIC12F675 Tutorial 6 : Driving a standard servo motor with a PIC

Servo motor driver tutorial. This tutorial uses the 12F675 microcontroller to drive a servo. The microcontroller generates the signals to control a standard servo using Timer 0 interrupts (I used a Futaba servo). It does not do anything clever just sets the servo position to predefined positions at one second intervals. A Timer 0 interrupt

How to interface RFID with PIC18F4550 Microcontroller

RFID (Radio Frequency Identification and Detection) is widely used everywhere from highly secured defense laboratories to school attendance system. By employing RFID, much secured entry systems can be developed without incurring huge costs. These are the reasons of excessive use of RFID technology. In this article, interfacing of an RFID reader module has been explained
