The Digital to Analog Converter (DAC) turns bits into waves using a surprisingly simple circuit built from little more than a few resistors. Learn how to build your own R-2R DAC and use it to generate waveforms with a microcontroller

Connecting Sensors and Microcontrollers to the Cloud
Give your gadgets a brain! Previously out of reach for the do-it-yourselfer, the tiny computers called microcontrollers are now so cheap and easy to use that anyone can make their stuff smart. It’s called “physical computing” — with a microcontroller, your gadget can sense the environment, talk to the internet or other gadgets, and make […]
I especially like the use of staples as emergency jumpers.
[W]e are introducing further microcontroller alternatives into the Fritzing ecosystem. In the new release, due tomorrow, you will already get this sweet array of choices. Besides the Arduino and its variants Mega and Nano, you can now use Modified’s pico, mbed, Wiring and Wiring Mini, Basic Stamp, Propeller
Hpropman presents a group of four tutorials about how to connect common motion detecting devices to a microcontroller for triggering haunt props. He has separate tutorials for flood light motion sensors, wall switch motion sensors, X10 wireless motion sensors, and Parallax motion sensors.
IEEE Spectrum has a great package of articles covering 25 Microchips that shook the world. All of your faves are there: the 555, the 6502, the 8088, the TI TMC0281 (which ET used to phone home), the PIC 16C84, the WD1402A (aka the first UART chip), the Z80, and the Sh-Boom coprocessor. The wha? Here’s […]
