I have a project that uses 7 analog inputs and hence I got the Arduino Mega. I was planning to store my sensor data on an SD card using a shield, but I don't see one that connects to all the pins of the Mega? Is that right? Do I have an option here?
Not sure I follow - ADC0 to 15 are all brought to headers.
Or did you mean the SD card? Those connect to the SS pin and the SPI pins SCK-MISO-MOSI.
I meant the shield. Can you point me to the one that connects to all the analog pins? I have only seen ones that connect to the Uno. Is there a different one for the Mega?
Not sure if this is right for what you want but maybe it's a starter.
I have a Ethernet shield which has a SD card slot onboard. My Arduino is a Mega, the shield is pretty much the same size board as the Uno, It headers connect through ALL the pins that would be on the Uno meaning that those pins are still available from the shield + the additional pins that the Mega has are available from the mega it's self. Just be aware of the pin numbers used by the SD
I hope that this makes sense for you and is of some help
Image below is not mine, it's from Amazon but it shows the setup
Can you point me to the one that connects to all the analog pins?
Why? Why do you need the SD card shield to have that many connections? The shield is NOT going to magically read the analog (or digital) pins and record the data.
I ended up getting the micro SD card breakout board and am successfully writing data to it. Thanks for the comments.
