The 8-Pin Programming Shield allows you to program ATtiny series chips using the Arduino itself as the programmer. In other words, you plug this into your Arduino and then you can easily program 8-pin chips. These small microcontrollers can then be incorporated into any project that you want. Follows are instructions for assembling your own 8-Piin Programming Shield.

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

In this article you will learn how to programm an ATtiny mcu using Arduino IDE.

Follows are directions for programming the ATtiny microcontrollers using the Arduino IDE. In plain English, this is how to program 8-pin Atmel chips as you would normally an Arduino. This is cool because the ATtiny is tiny, and – well – this allows you to make tiny things that don’t need a big ol’ microcontroller.

Tom posted his Arduino PID controller shield in the dangerous prototypes project log forum:

Program a temperature profile to mash beer or reflow solder. Here’s how.

This full featured open source PID controller uses a DIY stripboard shield for Arduino Uno and compatible boards. Firmware based on osPID massively revamped and extended, blood was sweated over new auto tune routines. Standalone or remote operation over UART using Java GUI. All documented on Github with BOM, schematics, code, pictures etc. Parts cost about $15, external SSR module and Arduino required.

I spun this project as a kit for Tayda, with the idea that all the components could be cheaply ordered in one place.

This article describes how to use infra-red (IR) sensor with Arduino or with a simple OPAMP comparator. Lee Zhi Xian writes:

What is infra-red (IR)? Infra-red is an electromagnetic wave who wavelength is between 0.75 microns to 1000 microns (1 micron = 1µm). Since infra-red is out of visible light range, we can’t really see IR with naked eye. However, there is a method to “see” IR which will be shown later on. Some of the infra-red applications includes night vision, hyperspectral imaging, and communications. We also use IR daily in our TV remote or any device remote.

IR transmitter and receiver can be obtained at low price. Their shape is looks exactly the same as LED. To distinguish between transmitter and receiver, the transmitter always come in clear LED while receiver is black in colour. Other than that, there is also receiver that is used to pick up specific frequency IR, 38kHz. For your information, 38kHz frequency IR is commonly used in remote control.

NavSpark is an arduino-compatible board with GPS for less then $20:

NavSpark is a small, powerful, breadboard-friendly, 32bit development board that is Arduino compatible, with a world class GPS receiver as on-board peripheral, and under $15.

There is also NavSpark-BD, a variant model having world-class GPS/Beidou receiver as on-board peripheral, that enables you to adopt new GPS/Beidou satellite navigation technology when Broadcom Qualcomm just recently came out with solution supporting Beidou to their tier-1 smartphone customers like Apple and Samsung.

NavSpark puts leading edge satellite navigation technology in the hands of the makers.

John Boxall over at Tronixstuff has a series of Arduino tutorials. This chapter fifty-three of a series will show you how to use the TI ADS1110 16-bit ADC with Arduino:

Moving on from the last chapter where we explained an 8-bit ADC, in this instalment we have the Texas Instruments ADS1110 – an incredibly tiny but useful 16-bit analogue-to-digital converter IC. It can operate between 2.7 and 5.5 V so it’s also fine for Arduino Due and other lower-voltage development boards. This is a quick guide to get you going with the ADS1110 ready for further applications.

DM&P has been producing low-power, x86-based Vortex processors for the embedded market for over ten years. Now in a nod to the Arduino market they have released the 86Duino Zero, a low-cost Arduino Leonardo sized board powered by their latest 300 MHz SoC Vortex86EX Processor.

This is a fully static 32-bit x86 processor board compatible with Windows OS, Linux and most other popular 32-bit RTOS. It integrates a PCIE bus, DDR3, ROM controller, xISA, I2C, SPI, IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included). The 86Duino Zero’s ports include USB 2.0 host and device coastline ports, a 10/100 Ethernet port and a microSD slot on the bottom of the board. The Zero’s baseboard also provides a 7-12V power jack, a reset button and a PCIe expansion connector.

The Zero supplies 14 digital I/O pins, half of which can provide 32-bit resolution PWM outputs and six 11-bit analog input pins. Each standard I/O pin supplies 16 mA while the 3.3 V pins can supply up to 400 mA. Like the Intel Galileo development board announced several weeks ago the 86Duino Zero marries Intel architecture to the Arduino platform. Its $39 price tag makes it an attractive proposition. [via]

Gert van Loo, the Broadcom employee responsible for the RPi alpha build has now come up with the Gertduino. He also gave us the GertBoard GPIO Expansion board some time ago which provides general purpose I/Os, LEDs and motor driver capabilities for the Rpi. Gert’s latest creation, the Gertduino board, plugs onto the RPi and connects it to virtually any existing Arduino Shield. The board itself basically offers the same functionality as the Arduino-Uno but with some added features thrown in.

As well as an ATmega328 and ATmega48 (both of which can be programmed from the Raspberry Pi using the Arduino GUI or the GCC Atmel compiler), the Gertduino packs a real time clock, 16MHz oscillator, IRDA interface, RS232 level converter and a battery back-up power supply for the ATmega48.
