This project is about building a PC-based temperature and relative humidity logger using the chipKIT Uno32 board and the DHT11 sensor. The project setup requires no additional wires (other than the USB cable) and components; the DHT11 sensor is ...

Economical alternative to original Arduino ethernet shields, allows data rates up to 10 Mbps and is achieved with a traditional assembly components. One of the most interesting shield that you can mount on the Arduino platform is certainly the ...

Seven segment LED displays are a very popular mean of displaying numerical information and finds application in front panel display boards of microwave ovens, washers and dryers, digital clocks, frequency counters, and many other gadgets. Compared ...

This shield could be used as a stand-alone transponder key, or with Google’s servers to create a cloud-computing application. It’s time to present you an application with RFID. We want to show you how to use the popular Arduino to ...

I needed a couple of AA batteries and found the display at the supermarket where they were all arrayed. Normally when I’m shopping in the supermarket, I tend to look at the price/kg or price/l when comparing similar products. In the case of ...

This experiment shows how to turn LEDs into light sensors. Since the Blinkenlight Shield has 20 of them this turns the Blinkenlight Shield into a 20 pixel „camera“. Schematics Before I explain why the schematics got their current form ...

Part 1 - How does RFID work, Whats stored on the card Part 2 - Schematic and PCB The software was next. Using the Arduino IDE, I implemented a simple menu system that allowed me to enter the relevant facility and CardID data directly from the ...

Part 1 - How does RFID work, Whats stored on the card So the next step was to identify how to pretend to be a card - I wanted a card that I could type a card number into, so it had to have a microprocessor on it, was well as a keypad to allow the ...

RFID projects have been pretty prominent recently, ranging from projects here in Instructables, to our local Silicon Chip magazine in Australia publishing a RFID door lock project in their November issue. Even I recently purchased a RFID door lock ...

Part 1 - Features, Schematic and Demonstration Seeeduino Description Seeeduino is Arduino compatible board based on Atmel AVR ATmega328. Its design is based on Diecimila scheme, 100% compatible to its existing program, shield and IDEs. On the ...
