ATMEL Project Board

Overview

If you are learning microcontrollers or want to quickly develop embedded solution based on standard 8051 core, this board will help you quick start with the application by giving you access to everything required to run the AT89S52 microcontroller. With this board you can develop and prototype with any of 8051 40 pin microcontrollers. The RS232 driver on board allows easy connection with PC or other embedded hardware . The board have User buttons and status LEDs. The bridge rectifire allow this board to be powered with both AC and DC power supply adapters.

Arduino Uno

Overview

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiringlanguage. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer. The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).

4 Wire Resistive Touch Screen Driver

Overview

Two of the four touch screen interface wires are for the X-axis and two are for the Y-axis. The pairs are operated on independently (e.g. the other pair is tristated by the microcontroller). The operation performed by the microcontroller on each pair is to apply Vcc to one wire and apply Gnd to the other. The wire to which Gnd is applied is also connected to an ADC input on the microcontroller, and the voltage read is proportional to the position being touched along that axis.
