g PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one of the many FTDI interfaces with added RS485 driver, or bought as assembled module. There is always the third option. I made it […]

Description The MAX98314 mono 3.2W Class D amplifier provides Class AB audio performance with Class D efficiency. This device offers five selectable gain settings (0dB, 3dB, 6dB, 9dB, and 12dB) set by a single gain-select input (GAIN). Active emissions limiting (AEL) edge rate and overshoot control circuitry and a filterless spread-spectrum modulation (SSM) scheme greatly […]

There has not been a simple addressable LED library for PIC32 microcontrollers until now! The PICxel library is an MPIDE library that handles the timing required to use addressable LEDs (WS2812, WS2811) or more commonly known as Adafruit Neopixels. Going through through a couple steps will allow your to get started with the PICxel library. […]

This article shows how to use the PIC16F84 microcontroller with PicBasic to design a quick & effective, serially controlled, I/O-Expander.  Using PicBasic makes developing handy single-chip devices like this extremely simple. If you’re spending all your time programming in assembler, you’ll appreciate how simple PicBasic is to use, and how easily you can create single-chip […]

Hi Guys! This is a project that I made using pic microcontroller its an Electronic PIN Code Security System with real time clock and user define pin code features, this page contains all the details to make one yourself. ITS WORKING AND CONCEPT: Well by turning Security System on, it will ask for a PINCODE […]

I wanted to try my hand at a true “DIY” project, designing and building my own micro quadcotper frame and writing my own firmware in C++.  In this post I will describe the frame and build; in my next post I will talk about the firmware. Excluding stuff I had lying around the shop, (heat-shrink […]

AN589 is microchip’s application note for a parallel port pic programmer circuit which I chose as I wanted something reliable to get up and running quickly. Note: This page is left on site for legacy information that is applicable to older computers. These days PCs and laptops have only a USB interface so a parallel […]

With all LEDs you will need a power supply, some sort of way to send a signal (usually a microcontroller) and method of connecting the LED to your system… Admittedly, that sort of explanation is all things pretty vague (as a description), so instead it’s my opinion that the easiest way to explain the LEDs […]

If you are into PICs, you maybe tried one day or another to build a software video processor, either for fun or for a project. If you tried to generate video signals, you surely know some of this web pages : Rickard Gunees PIC PONG page : http://www.rickard.gunee.com/projects/ Eric Smith video clock : http://www.brouhaha.com/~eric/pic/pictock.html This projects […]
