Arduino Using an SD Card and Digital Signage On a Raspberry Pi - Let's Make it - Episode 50

 

This week we show you how to use an sd card with an arduino to log data. We also show you how read a file on the sd card, manipulate files and get details like card size, type and directory of files.

 In our second segment we show you how to turn a raspberry pi into a digital signage device. All for nothing more than the cost of the raspberry pi.
