Aurora 9 bar – The Essence of Aurora Since the introduction of Aurora 9×18, I received many requests for the kits and PCBs. I’m still quite undecided about making those available for a few reasons. However I really want other LED lovers (ok that might sound too much to be able to build one themselves. […]

Project description: In this project, 8 LEDs are connected to PORT B of a PIC microcontroller. Also a push-button switch is connected to bit 0 of PORT A using a pull-up resistor.. When the switch is pressed the LEDs scroll to the right. Hardware: The circuit diagram of the project is shown in Figure 1.

description This circuit can be used to operate an electric strike or an electromagnetic lock on a door. It is not the door being opened/closed, but a small electromagnetic strike which unlocks the door. The opener has the following features currently programmed in software: automatic operation when a guest pushes the doorbell, the strike is
I was bored this past sunday, and needed something to ease my racing brain … so I picked an easy project with lots of flash. The parts list: Eight Tri-Color or RGB leds … each led package contains three LEDs Three 74HC595 Shift Registers … serial load, latching. other varieties would probably work too. One

In this article I used in banks and hospitals will give information about the Q-matic s. I’ve done a routing circuit board (main board) and consists of three separate teller. Routing PIC16F877 on board, if the teller did not use pic16f876 in each. Teller as the officer may increase, decrease or can be reset. Every

I am a big fan of LEDs. Bright, colorful, flashing LEDs. So, given my affinity for LEDs, I decided to work on a controller that me and a few of my friends could use as an art project/passive information display. I have posted videos from the first prototypes (here and here), but it has been

Welcome to another chapter of PIC18F programming Tutorial. In this chapter we are going to program a simple 28 pin PIC18F2550 microcontroller using mplabx IDE and XC8 Compiler. The concepts for programming a pic18f2550 microcontroller is still going to be almost same as previous tutorials on pic18f4550 microcontroller, however since pic18f2550 is a different microcontroller

Short description of the operation: External circuit converts bass beat of music into pulses. The motor is controlled by them. If theres bass beat recognised then the motor rotates one direction (in full stepping) for a predefined time then stops. If the second beat comes in then it rotates again for the same time and

Electrical The main components of the electrical system were the timing system and the LED control system for 40 LEDs using a single PIC. A schematic of the system is shown below (click for larger view): timing In order to time the display properly to achieve persistence of vision, the PIC needs to record the

Rotary encoders are very versatile input devices for microcontroller projects. They are like potentiometers expect of digital nature and unlike analogue potentiometers they never wear down. Rotary encoders not only provide 360 degrees of rotational freedom they also allow digital positioning information to be gained without the use of analogue to digital converters (ADCs). When
