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 ...

The topic of this post is building sine wave generator based on Arduino UNO and PCF8591 8-bit A/D and D/A converter. For similar design with PIC micro-controller look at this link. Raspberry Pi version based on MCP4725 DAC available at ...

A few weeks ago I’ve uploaded post with relatively simple assembly code example for interfacing 2x16 LCD display with PIC16F microcontrollers. Driving Graphic LCD display is more complex task  as it lacks the build in character generation unit so each pixel needs to ...

3 Digit Up Down Counter shown here is based on PIC16F877A microcontroller. The count is shown on the 2x16 LCD display and the direction is controlled by a switch connected to bit 3 of PORTA. With minimal changes the attached ...

In this post I'll show you how two QDSP-L149 5x7 dot matrix  LED Displays can be used to create a  4 Digit display module. The trick is to change  the roles of rows and columns. So now each 5x7 Dot ...

In this article I’m going to show you how an 8x8 LED Dot Matrix Display can be driven by MAX7219 with Arduino.There are 2 similar designs. PIC16F876 version is  available at this link ,for circuit based on 74HC595 click here.For this project ...

Here is another modification of a digital voltmeter. This time with 7 – Segment LED Display. These circuits seems to be more popular than other designs so I’ve decided to  publish another variant. You can find 4 variations of digital voltmeter on ...

Have you ever wondered how to generate a sine wave using PIC microcontroller. In this post I’ll show you a simple circuit design that can generate arbitrary wave forms including sine by using MCU and PCF8591 D/A converter. For similar design ...

In this post a simple Digital Dual Voltmeter and Ampere meter design will be shown. It uses PIC16F876A microcontroller and 2x16 LCD display and has 2 input channels for measuring voltage in 0-25v range and current up to 500mA. The ...

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 ...
