Running LED dice

Running LED dice

Tons of LED dice projects with different output forms have been published online. The most common output configuration in those projects is a 3-1-3 setup (two rows of three LEDs and one LED at in the middle) of seven LEDs, which simulates the actual patterns of dots found on the six faces of a traditional […]

PIC USB HID Human Interface Device Interfacing

PIC USB HID (Human Interface Device) Interfacing

For long time, UART is the only and best way to interface with PC. It is easy to adapt and handle. Though some devices (like: GSM modem etc.) have UART on themselves, but for interfacing with PC, there is only one thing now and that is USB Introduction The purpose of this article is to […]

Schematic Automatic Power Factor Controller using Microcontroller

Automatic Power Factor Controller using Microcontroller

The thirst for new sources of energy is unquenchable, but we seldom realize that we are wasting a part of the electrical energy every day due to the lagging power factor in the inductive loads we use. Hence there is an urgent need to avoid this wastage of energy. Before getting into the details of […]

8049 Spy

8049 Spy using pic microcontroller

What do you do when you have to read the internal ROM contents of a 8048 or 8049 processor and you don’t own a programmer for those devices? You simply build this 8049 spy of course! That is exactly what I did when I wanted to know how my Philips Frequency Counter PM 6668 worked. […]

Interfacing Relay with PIC Microcontroller

Understanding the Role and Function of Relays in Electrical Circuits

A relay is an electromagnetic switch which is used to switch High Voltage/Current using Low power circuits. Relay isolates low power circuits from high power circuits. It is activated by energizing a coil wounded on a soft iron core. The Role and Function of Relays include controlling the flow of electricity between circuits, providing electrical […]

dsPIC breadboard

Breadboard using dsPIC30F2012 microcontroller

Bernard introduces us to the dsPIC microcontroller. He shows us his Arduino like project board for a dsPIC and gives advice on software development tools. This article was submitted by Bernard Klinc as part of the “Hobby parts for articles” program. Bernard received a graphic LCD module for this great article. You may remember Bernard […]

How to use PIC18F4550 as a SPI Slave Transmitter

How to use PIC18F4550 as a SPI Slave Transmitter

The Serial Peripheral Interface (SPI) is a high speed, synchronous, serial communication standard. This communication protocol is basically a Master Slave implementation where the master device controls the clock based on which the slave devices operates. The master can communicates with one or more slave in the system through SPI bus. The SPI bus requires a […]
