Hey there,i have this question.Can i use both an sdcard datalogger and a bluetooth module ht05 with my arduino uno together. I am trying to get the input from an android device to the arduino uno using bluetooth and then compare the input from the values already stored in the sd card and then save the correct values again in a different file in the sd card.It will be helpfull if u give a proper way to do so.
SD and bluetooth use different pins and there is no problem operating them together on the one Uno. There is a "serial input basics" sticky on this forum. That and the SD card examples in the IDE should have all you want. I don't think you can have more than one file open at a time, so just remember to close files when you are not using them.
Hey Nick, thanks for the response.but dont both hc 05 and sd card datalogger use the rx tx pin of uno?
I have never heard of an SD card on serial, so no. SD cards are routinely on the SPI bus.
