This post is about building a simple LED controller circuit. Several articles were published on this subject. Here is just one link to similar design that can be useful. Search the site for more information. Current design  relies on well-known technique to ...

This article shows how to create a fading/dimming effect of the LED using PIC micro-controller. For similar design based on Arduino click this link.Controlling LED brightness using PWM is a relatively simple task and can be accomplished by configuring PIC16F877 ...

A simple wave generator should be a part of every electronics enthusiast toolset. Basic Sine/Square output in reasonable frequency range will be sufficient for general use. Luckily such generators are available in form of a very popular AD9850 module.  Search ...

In this post I’m going to show you how to interface an I2C Real Time Clock – RTC with PIC microcontroller. Only a basic hardware configuration and a communication protocol are presented here. I’m planning to extend it to a ...

This is a modified version of basic wave generator design with AD9850 and Microchip PIC16F microcontroller. A relatively simple assembly code available for download at the bottom of the page. Instead of using a rotary encoder as many other similar available ...

In this article I’ll demonstrate a digital stopwatch design based on PIC16F876A micro controller.For related circuit based on Arduino click here. Similar project showing a Digital Timer design can be found here. Current circuit can be used to count in ...

In this post I'm going to show you how to build a simple Digital Lock using PIC microcontroller. Instead of building a new hardware design from scratch we are going to use PIC Development Board as a basis for Digital ...

If you ever thought how fast you can react to external stimulus here is the circuit that can measure your response time. It measures the time it takes for you to press the push button in response to  turning the ...

For this project two PIC16F877 MCU's were used, see project schematics below. Slave PIC runs  LEDs decoding and multiplexing code on data received from Master. 7-Segment inputs connected to PORTC,B and common digits anodes to PORTB,A via 2N3906 collectors for ...

This article shows a basic interface between PIC16F microcontroller and a unipolar stepping motor using an assembly code. For programming the MCU you'll need PICKIT2 or PICKIT3 device. Similar design for Arduino platform can be  found at this link. Instead ...
