Are you ready to say Hello World? Today we’re releasing the second lesson in our new course: An Introduction To Microcontrollers is live. Here’s an overview of the lesson:

"Building a ‘hello world’ application signifies a time honored approach to learning how to program. In this lesson, we will explore the first steps necessary for building and loading programs onto a microcontroller."

"The DIY pick and place machine project is now finally running and is able to place the components for our Raspberry Pi expansion boards. This project started in July 2013 when we began to order the various components, bearings, motors, drive systems, frame materials etc and we started to build the machine in September."

"The objective is to use readily available ‘off-the-shelf’ low-cost consumer components where possible, and to design electronic subsystems where such components are either not readily available or are too expensive. In terms of affordability, the overall goal is to design a robot that can be made for around the price of a PC."

"Jonathan Ward from the MIT Center for Bits and Atoms has designed a snap-together, desktop-sized CNC milling machine. The MTM Snap is made from 1/2-inch high-density polyethylene (HDPE) – itself milled on a ShopBot – and can be assembled for about $700. This three-axis CNC machine can mill circuit boards, wax molds, and harder materials in a 5x3x1.75″ working area. "

"Mister Gloves is a wireless USB gesture input system that enables a person to use a computer by performing intuitive hand and finger motions in the air. While wearing a glove controller on the right hand, the user can move the cursor by forming a pointing gesture and click by curling the index finger or thumb."

"A PID controller is like a kind of fancy thermostat, but can be used to control pretty much any kind of process, not just heating and cooling. This project was inspired by the osPID and its design is greatly indebted to that pioneering device."

"The mood that the ‘Magic Crystal Mood Ball’ gives to the user is based on measuring his temperature and changing the color of the RGB LED to the its respective color. As in a mood ring, I set different colors for different temperatures. The temperatures coincides with mood state that the person is in."

"Driving a shift register using an AVR chip’s built-in hardware is really quite easy. Most of their offerings have an SPI module, or Serial Peripheral Interface. A shift register is exactly that, a peripheral device that communicates via a serial line. All we need to do is hook up our connections and use a few pieces of simple code. Join me after the break to see how that’s done."
