Hello,
I’ve Grove EMG detector & Base Shield connected to Arduino Mega, and I tried uploading the demo code from What is EMG sensor, Myoware and How to use with Arduino? - Latest Open Tech From Seeed
but when I try to upload it tells me that LED_bar.h can’t be found. I’m somewhat familiar with C/C++, so I understand that this is because the file can’t be found, but where should I get it and where should it be put so that I can get this to work?
You have to download and install the led bar.h library. You can download it from here:

By the way, if you ever wish to make an EMG amplifier by yourself, you can see this design:
