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 ...

This post is about building a basic distance meter with ultrasonic HC-SR04 sensor and PIC micro controller. For Arduino version click here. Raspberry Pi variant is also available at this link The interface is very simple and does not require too many commands ...

This is an update to a recent post on a subject of building a Digitally Controlled Power Supply. In part 1 a basic configuration was presented. In this version a numbers of modifications were made to software/hardware to produce a more advanced ...

This post is about building a simple PIC16F88 based DC motor controller. Motor speed and direction can be controlled by two push buttons SW1, SW2. One for motor speed and the other for polarity. This post follows recently published projects like PWM ...

This post is about building a Simple IR Proximity Sensor based on PIC16F877a micro controller. Usually these simple circuits are built using discrete components and include an OP AMP for comparing the photo diode voltage to a preset value. Current ...

3 Digit Dot Matrix Display with SPI interface is an advanced version of recently published 7x5 Dot Matrix Character Generator project. This design is more complex as it contains 4 microcontrollers. Three PIC16F88 were used to control 7x5 Dot Matrix Displays, ...

Simple digital voltmeter can be built by using PIC microcontroller and a few discrete components. PIC16F877A 10 bit ADC module was used for this purpose, we’ll work only with 8 upper bits to translate input voltage to digital form and ...

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 ...

Power Supply is probably the most common electronics project you can build.This is a basic design for digital power supply. It was built around 3 main components. Digital potentiometer – MCP4251-502E/P, Low  Dropout Voltage Regulator – MIC29152 and PIC16F877A.The idea ...
