I need help with my Arduino project for school
Hello thanks for reading thisš,
I'm currently making a robot for school that should move his servo motors and must play saved wav files from the SD card, when a letter (for example h) gets sent trough Bluetooth (with HC-05) to the Arduino. My only issue is that for some reason I can't use the HC-05 and the SD Card Memory Modul at the same time. I can use the HC-05 while SD Card Memory Modul is unplugged and the letters arrive at the Arduino and the servo motors will move without any issue. And I also can send letters trough a USB cable connected to my pc, while the HC-05 is unplugged, and those letters arrive to the Arduino, the SD card will play the wav file and will move its servo motors without any problems. But every time I use both at the same time (HC-05 and SD Card Memory Modul, that's my goal) it seems like the letter gets sent to the HC-05 but will never arrive at the Arduino itself. I think the problem could be that the SPI of the HC-05 and the SPI of the SD Card Memory Modul are interrupting each other somehow, but I almost don't know anything about SPI lolš
.
I used Chat-GPT and watched tutorials online but nothing worked for me, I don't know how to fix this issue .

For some reason line 38 returns an error. The user is expected to enter the price of an item on a 16-key pad. Press * to accept, # to decline. It's expected to convert the price thing to a double to add to the total, but why it aint working?
Timing LED challenge
Task
Blink at least 3 LEDs at the same time.
Each LED should blink at a different interval. For example the first LED blinks every 200ms, the second one every 500 and the third one every 900.
