Play Shield for Wiring S
|
The Play Shield acts as an adaptor for shields with Arduino form-factor.
It also provides room for a 24LCxx EEPROM and RTC DS1307 clock on I²C bus, as well as 4 push buttons and 6 LEDs. |

On the right, the DS1307, crystal and battery are mounted.
Time is displayed on a µOLED-160-G1(SGC) with the Serial_LCD Library Suite. |

Caution!
|
The Play Shield is potentially hazardous.
Two pins on the Play Shield may be in contact with the metallic enclosure of the USB connector. I've experienced such risk; the resulting short circuit fried both the 24LC512 EEPROM and the RTC DS1307 circuits. |
