Temperature-indicator and temperature-based products have generated wide interest. There are numerous applications for such devices with many possible solutions, each with its own advantages and disadvantages. This idea discusses a sensor interface ...

Zoltan Gingl Two configurable analog ports allow you to connect many sensor types using two three-input connectors, each of which has a ground pin (Figure 4). One ground pin provides 3.3V power, and the other outputs the buffered reference voltage ...

A precision analog acquisition system fits in your pocket. The circuit in this Design Idea combines a mixed-signal microcontroller, a USB UART (universal asynchronous receiver/transmitter), and a novel adaptable analog sensor-input circuit. It ...

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 ...

Rajendra Bhatt, Nepal The use of a graphical LCD (GLCD) drastically changes the look of your project. It provides more freedom for presenting data than the HD44870 based character LCDs. Today we will see how to interface a KS0108 (name of the ...

On my desktop PC I have a speakers and a headphones. Usually I use headphones, but when I need to switch to speakers I need to physically plug in speakers instead of headphones to my PC’s soundcard. I wanted to solve this problem for a long ...

USB Generic HID C# Communication Library The USB communication and USB specific functionality (such as device attach and detach detection) is provided by the USB Generic HID Communication Library which compiles as a DLL under Visual Studio 2010. ...

ATmega32U4 Firmware The reference firmware is an AVR Studio 5 project which includes both the framework code and the required parts of the LUFA stack. There are two independent firmware types the 'reference firmware' which provides the ...

The Atmel AVR range of USB capable devices provides a wide-range of functionality and peripherals to the professional and hobbyist; however the additional complexity of both microcontroller firmware and host PC drivers is a tall barrier to anyone ...

Part 1 - Schematic This device's design is based on the Low Pin Count Development Kit hardware from Microchip , Microchip Solutions has example programs for that development kit so it is quite easy to get them running on the device covered in this ...
