(+1Month Warranty) Arduino MultiFunction Shield Expansion Board Learning Beginner Shield DIY [ElectricA]

Arduino is a great way for today’s novices to start to learn how to write and run codes that interact with the external world. Somebody on Facebook recently asked about finding an easy-to-use shield helpful for experimenting with Arduino wherein he wants to try a single one instead of a number of luxurious shields. Luckily, requisite googling found a “multifunction shield” for the Arduino Uno platform available at a low cost from most internet suppliers.

The multifunction shield features some most useful electronics divided into segments:
Four LEDs
Three pushbuttons
A reset button
A piezo-buzzer
An LED display module (four-digit, seven-segment)
Two serial LED display driver ICs(74HC595)
A multi-turn trimpot (10K)
A port for DS18B20 temperature sensor
A port for TSOP1838 infrared receiver module
A APC220 wireless module interface (serial/UART interface)
