A switch input is one of the simplest interfaces to an MCU. However, when very low power designs are needed the pullup or pulldown resistor for the switch can draw a significant current. If the switch input is a momentary switch the current flow is very short so it is rarely significant. However, if the […]

The Color Matching Game! Posted on February 18, 2013 by Dillon Reisman Group Members: Sam Payne, Prerna Ramachandra, Dillon Reisman, Abbi Ward Early idea sketches: 1) Gummi-Bear RGB color-mixer! 3) The “Waker-Upper” Idea actually implemented: We built a color matching game. The computer will generate a random color, then the user must use a touch sensitive
What’s SODAQ? Prototyping should be rapid. Putting projects together should be as easy as clicking together lego-like building blocks. SODAQ makes it so. SODAQ is a multi-feature microprocessor board that lets you connect sensors and devices to the internet, quickly and with no fuss. It’s designed for connecting things efficiently, running off-grid with built-in, ready-to-go

Dearest Spark friends, Our new hardware is here! In case you’re not feeling the length of this post, here’s the short version: Today we’re launching our new development kit, the Photon! It’s the spiritual sequel to the Spark Core (backwards compatible), and it’s faster, better, and cheaper. You can pre-order it now for $19, and
How Dottie Was Made My trusty Arduino (it’s red, a clone from Sparkfun, and it was on sale for $10) begins this journey to reverse-engineer a flip-dot board. I figure that if I can flip one single dot, using a shift register and a couple of transistors, then all I need to do is replicate
Introducing the Sweet Pea WiFi Shield Have you ever wanted to include WiFi functionality into your Arduino system but been scared away by the shear cost and complexity of it. Not to mention that you normally want to have a few other things in there such as maybe an SD card to be able to

Intel announced its 4004 processor and its chipset through an ad in Electronic News on November 15, 1971, making them the first complete CPU on one chip and the first commercially available microprocessor. The building-block 4004 CPU held 2300 transistors. The microprocessor, the size of a little fingernail, delivered the same computing power as the
