This project is based on ideas from Rickard’s electronic projects page and David B. Thomas VCR Pong. However, I have developed the simplicity even further, eliminating most of the external components. Using microcontrollers with internal 4MHz clock generator there is no need for the xtal. The 12f675 part also operates on wide voltage range, and […]

Many people using Arduino or some other development board in their projects, instead of making their own board with microcontroller because they simply don’t know how to design PCB with microcontrollers. What microcontrollers need in order to operate? This time I will be focusing on two most popular 8 bit micro architectures: PIC Microchip .

Quick & Easy RGB-LED Tester Have you ever built a project with a lot of LEDs, and found out that one of the LEDs was defective? Although it’s somewhat rare, there are some defective LEDs when you go through hundreds of them. I found that RGB-LED have high defect rate, most likely due to the

How chords are formed Before discussing the processor board and software, it is worth mentioning how the chords are composed. I have provided the table below which shows the installed chords together with the intervals/notes they are constructed from, and examples of each in the key of C major. Since the source-code is provided, and

The design uses the PIC18F series microcontroller. All the control functionalities of the system are built around this. Upgradeability is the unique feature of this system. Control card hardware and software allows the manufacturer to add or remove the features as per customer requirement and model. Thus once the whole system is designed it is
Every time I sit down to document one of my projects, I try to remember the occasions in the past when looking at the finished web page, I might say ‘Well, I won’t do that again!’, because despite how many drafts I’ve gone through, there is always some aspect of the presentation that fails to

Another method that helps program development besides a dot LED as the output device is a serial bit. With a serial transmission to a terminal emulator program, developer may then test program running easier than a dot LED. One of my circuit uses PIC16F84 having one bit for sending ascii character with “printf” function. The

As part of our final project for ECE 4760: Digital Systems Design Using Microcontrollers, we built a guitar amplifier with remote distortion and digital effects capabilities controlled from a smartphone via bluetooth. Musicians often need to modify the configuration of their amplifiers when performing in concerts. This job is generally delegated to “roadies” who walk

General description erberes is a small three wheel robot that avoids obstacles which it senses with its active infrared sensors. Each rear wheel has its own motor, the single front wheel is not powered. The robot steers “like a tank” by rotating the rear wheels in opposite direction. The sensors are built with infrared LEDs

Introduction The F84 MRTC was my second design of a miniature real-time controller. This version uses PIC16F84 running with a low power X-tal 32,768Hz. The scheduler for 6-channel output was saved in EEPROM. No terminal for serial downloading of the scheduler. It’s suitable for fixed scheduler job. Two AA size battery provides +3V backup for
