This is an ongoing project to control a number (currently 5) of Lamina Atlas high power (350-500mA) LEDs. Current progress includes: PCB artwork (in Eagle) with connections for 5 RGB LEDs. Firmware for a Microchip PIC16f887 microcontroller to interface between the FTDI 245R USB chip and a number of Texas Instruments TLC5940 constant current LED […]

The time keeping is provided by DS3231 RTC chip with an integrated high accuracy (± 5ppm) MEMS crystal. This makes PCB design very simple, as one does not need to take care on special traces design around the crystal. The chip is powered via the VBAT pin with VCC pin being grounded. This way its […]

Ranked one of the top three must-attend events in the embedded industry, ARM® TechCon™ is more than a conference. ARM TechCon’s unique 360-degree interactive training ground seeded to connect, instruct, advise and enable the world of electronic and ARM-based computer design provides attendees with a comprehensive understanding of ARM-based technology. ARM TechCon Is Designed For: […]

SAN JOSE, Calif. – June 16, 2015 – Fairchild (NASDAQ: FCS), a leading supplier of high-performance semiconductor solutions, today launched the FIS1100 6-axis MEMS Inertial Measurement Unit (IMU), the company’s first MEMS product stemming from its strategic investments in MEMS and motion tracking. The FIS1100 IMU integrates a proprietary AttitudeEngine™ motion processor with best-in-class 9-axis […]

How many ways can you use a self-contained, high-precision signal source contained on a 1″ x 2″ plug-in circuit card? How about as a stand-alone VFO, a signal generator for your bench, a replacement LO for your Sierra or NC40 transceiver, or perhaps as the heart of an antenna analyzer! Control it with your favorite […]

A Word Clock ************************************************************************** Major updates – A much better enclosure for this clock has been designed, and a better controller using an AtMega controller now exists.  check out http://www.instructables.com/id/The-Wordclock-Grew-Up/ ************************************************************************** This is a project to tell the time using words. I saw a cool clock on the Make Blog the other day (http://blog.makezine.com/archive/2009/09/qlocktwo_clock_tells_time_with_word.html), and […]

This is one project that i’m doing, now I’m going to show how to do it only for one motor, but i’m using and DEMUX to in the future use 4 motor. The project is simple, it uses the pic to control the DEMUX and the DEMUX control the H-BRIDGE that control the motor forward […]

With only 35 instructions to learn the Microchip PIC microcontroller assembler language is considered very efficient and easy to learn; you will not find such as Atmel AVR microcontroller CP (compare) and BRNE (branch if not equal) or BRGE (branch if greater or equal) on the PIC microcontroller assembler language dialect, instead it’s just provide […]

This is the lowest-cost dialing alarm on the market and shows what can be done with a PIC microcontroller. The complete circuit is shown below. You cannot see all the features of this project by looking at the circuit – most of them are contained in the program. So, read on and see what we have included. […]
