Would be interesting if we could make our microcontroller to sing for us not just beeping or blinking; this project is all about using the powerful AVR ATmega168 16-bit PWM feature to produce accurate musical notes such as playing the child’s favorite Twinkle-Twinkle Little Star song or we could say beeping with style.

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced its first instrumentation amplifier, the MCP6N11. The new instrumentation amp features Microchip’s unique mCal technology, which is an on-chip calibration circuit that enables low initial offset voltage and a means to control offset drift, which results in higher accuracy across time and temperature. The MCP6N11’s low-power CMOS process technology enables low power, while providing a gain bandwidth product of 500 kHz, and it features a hardware shutdown pin for even more power savings. The device’s low, 1.8V operation allows two 1.5V batteries to be drained beyond typical use, and its rail-to-rail input and output operation enables full-range use, even in low-supply conditions.

Russ connected an MCP4822 dual 12-bit digital-to-analog converter (DAC) to the fine Tektronix 2213A oscilloscope. A program (sketch) on the Arduino microcontroller drives the DAC and generates the image by steering the scope's CRT beam along the lines in the drawing (vector-scan). en.wikipedia.org/wiki/Vector_monitor

The chipKIT PGM is designed to work with the MPLAB® and MPLAB X development environments available from Microchip. This allows the chipKIT boards, for example, to be used as a more traditional microcontroller development platform using the professional tools available from Microchip. While the PICkit™3 programmer can generate programming voltages needed to program all Microchip PIC devices, the chipKIT PGM can only program devices that are programmable with 3.3V programming voltage. Further, the PICkit3 can source a small amount of current to provide power to some boards being programmed. The chipKIT PGM does not provide power to the board being programmed.

Microchip Technology's PIC18F87K90 8-bit microcontrollers (MCUs) feature nanoWatt XLP Technology, 1.8 - 5.5V Operation and CTMU Module for Capacitive Touch Sensing. The MCUs can also drive LCDs up to 192 Pixels.
This is one of my ongoing robotics projects... replacing (actually bypassing... I didn't want to do too much damage) the Big Trak's original onboard electronics and processor with some slightly more up-to-date parts: a PIC12F675, and a couple of Maxim 4424 motor drivers. This has mostly been an excuse to learn a bit more about programming microcontrollers, building circuits, etc. It mostly works, although the motor drivers don't quite seem to put out enough juice so the thing keeps stalling on me :(
Working on a simple quad, it's been a project I've wanted to do for quite some time, and some random thoughts I had led me to try it now.
This is the speed controller for it, it should be able to drive at 10A, maybe 15 or 20 depending on the duty cycle, and should be able to handle voltages up around 20V. It's designed to use back-emf and current sensing to measure performance. Firmware development is forthcoming once I get the boards back...

This fabric-based microcontroller project has been taking up more and more of my life. Every corner turned, every goal reached, opens up a thousand new possibilities and a thousand new tests to make.
Here I am with Tara O'Con, presenting at Maker Faire NYC. Thanks to Chris Cummings for the photo!

I think I can call myself an accomplished solder-er, after adding those header pins without a problem.
Microchip Technology's MCP14628 and MCP14700 Synchronous Buck MOSFET Drivers provide maximum efficiency in small packages. The new devices drive two N-Channel MOSFETs arranged in a non-isolated, Synchronous Buck converter topology. They feature excellent latch-up immunity, enabling extremely robust applications in the consumer and computing markets, such as digital power conversion, DC-to-DC power supplies, three-phase BLDC motor control and telecom equipment.
Gotta show off a little! I've had an itch to get back into microcontrollers for a while and finally bit the bullet and went for it! At my young age, I gotta keep the ol' brain active!
The Arduino micros are cheap and a very inexpensive way to create all kinds of fun projects! Programmable with C/C++ language, I've actually been able to remember quite a bit. It's been years!
"Hello World!" is the classic first code most folks write for almost every programming language.
Btw... the microprocessor is that tiny thing on the left with the red power LED. It's an Arduino Nano.
David presents an interfacing Arduino and Adobe Flash. Dorkbot crowd makes up a quick game called "Busy Proctologist" using some craft items, a pressure sensor, and the goatse image.
The crowd concluded after finding a latex glove, a styrofoam ring, some bubblewrap, and some red and brown felt, and a pressure sensor that the game would be called "Busy Proctologist."
Gameplay involves "examining" as many patients in the day as possible (measure by a 1 minute timer in Flash) without causing undue discomfort during the rectal exam (exceeding a moderate pressure range measured by the sensor and arduino.)
I made a Mandelbrot Set viewer with an Arduino. It does zooming and it's pretty cool.

One of the commonly asked questions when we move to the bigger and powerful 16-bit microcontroller is do we really need it? As the 8-bit microcontroller is already suite almost all of our needs from a simple blinking LED to more sophisticated embedded application such as robotics
When found by the artist, this small oyster shell had a perfectly round hole drilled into it, perhaps by a predator. The hole was a perfect fit for a light-emitting diode.
It dimly blinks the “Arecibo message,” a transmission sent towards star cluster Messier 13 from the then-new Arecibo radio telescope in 1974. Though it was considered a “message to aliens,” the Arecibo transmission was brief, less than three minutes in duration, and was sent only once. It was a demonstration of the telescope creators’ technical prowess more than an earnest attempt to advertise humanity.

My company, AVIX-RT, develops and markets an RTOS for Microchip PIC24/dsPIC microcontrollers. Since the main focus is on software, for hardware I am always looking for easy solutions where I do not have to spend a lot of time reaching my goals. I found such a solution with Schmartboard. Schmartboard enables me not only to create a converter, making it easier to work with SMD devices. Schmartboards offer much more than this. These boards allow me to put complete circuits on a single board reducing footprint and ‘Time to Prototype’, this all with minimal effort. I really love these boards since they allow me to focus on my main goals. More information can be found at www.avix-rt.com
