Arduino vs Raspberry Pi: Which Is The Mini Computer For You? You’re looking for a small computer to power a laser turret that can shoot multi-coloured balloons – it’s a common situation we all find ourselves in at one point or another – and you’ve heard good things about both Arduino and Raspberry Pi.
But you can’t decide – which the best mini-computer for your project? Which is going to prevail as the most useful once you’ve disassembled the turret thanks to that incident with the neighbour’s cat? Which could you play movies on? Don’t worry, James is here to explain all! What’s The Difference? The Arduino and Raspberry Pi may look quite similar – they’re both cute little circuit boards with some chips and pins on them – but they are in fact very different devices. Although the Arduino can be programmed with small C-like applications, it cannot run a full scale “operating system” and certainly won’t be replacing your media center anytime soon.
Strengths & Weaknesses So is the Arduino useless then? None So, you’re decided? WAIT! Arduino music projects. Pulse-width modulation. An example of PWM in an AC motor drive: the phase-to-phase voltage (blue) is modulated as a series of pulses that results in a sine-like flux density waveform (red) in the magnetic circuit of the motor.
The smoothness of the resultant waveform can be controlled by the width and number of modulated impulses (per given cycle) Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique that conforms the width of the pulse, formally the pulse duration, based on modulator signal information. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors. In addition, PWM is one of the two principal algorithms used in photovoltaic solar battery chargers,[1] the other being MPPT. The PWM switching frequency has to be much faster than what would affect the load, which is to say the device that uses the power.
And D. Through-hole technology. Through-hole (leaded) resistors History[edit] Through-hole devices mounted on the circuit board of a mid-1980s home computer.
Axial-lead devices are at upper left, while blue radial-lead capacitors are at upper right Axial vs. radial leads[edit] Components with wire leads are generally used on through-hole boards. Radial leads project more or less in parallel from the same surface or aspect of a component package, rather than from opposite ends of the package. When needed, an axial component can be effectively converted into a radial component, by bending one of its leads into a "U" shape so that it ends up close to and parallel with the other lead.[4] Extra insulation with spaghetti tubing may be used to prevent shorting out on nearby components.

External links[edit] FTDI Chip. Future Technology Devices International, commonly known by its abbreviation, FTDI, is a Scottish privately held semiconductor device company, specializing in Universal Serial Bus (USB) technology.
It develops, manufactures, and supports devices and their related software drivers for converting RS-232 or TTL serial transmissions to USB signals, in order to allow support for legacy devices with modern computers. FTDI provides application-specific integrated circuit (ASIC) design services. They also provide consultancy services for product design, specifically in the realm of electronic devices.
The company's flagship product is its FTDI Chip, an integrated circuit which is a common component on electronic devices using microcontrollers, such as the Arduino physical computing platform (up to before Arduino Uno). FTDI's headquarters are in Glasgow, Scotland, United Kingdom, while it also has offices in Taipei, Taiwan and Portland, Oregon. Beginner Arduino. The Arduino is a pocket-sized computer (also called a "microcontroller") that you can program and use to control circuits.
It interacts with the outside word through sensors, leds, motors, speakers... even the internet; this makes it a flexible platform for lots of creative projects. Some popular uses include: - programmable light displays that respond to music or human interaction - robots that use information from sensors to navigate or perform other tasks - unique, customizable controllers and interfaces for music, gaming, and more - connecting real world objects to the internet (twitter is especially popular) - anything interactive - automating and prototyping There are tons of amazing Arduino Projects posted online, here are some of my favorites: Twitter Mood Light by RandomMatrix, a light that changes color depending on what kinds of emotional words are trending on Twitter Nebulophone Synth by Bleep Labs: Singing Plant by Mads Hobye: Polargraph Drawing Machine by Sandy Noble:
