Can the Wave Shield and Data Logging Shield be used together

Post by siddy95 »

Hello,

I'm trying to build a service droid using an Arduino Uno.I am using an L293D to control 2 geared DC motors.

I wanted to add Data Logging (Temperature and Light readings) and Speech capabilities to the robot using the Data Logging Shield and Wave Shield respectively.

I was wondering whether both of them could be used together.I have some doubts since both use SD card slots and logic level shifters, this could
cause some arduino pins to overlap.

Is there any alternative way in case both the shields cannot be used together??

Thanks,
Sidharth :D

You can simply stack them if you only use one of the SD card holders. If you want to use both card holders, you would need to change the CS jumper on the Wave Shield and modify any software that uses the Wave Sheild card.

I plan on only using one SD card...will the arduino be able to read and write off the SD card in the same code? (Not simultaneously ofcourse).

Like access the sound from the memory card in one situation and later log the readings from the Temperature and light sensors on the same card.

Thanks :D

The Arduino and SD library don't care which card they are talking to. Both shields use the same SPI pins for the SD interface. You can play sounds and log data to the same SD card.
