I've been working with a couple of sensors lately, but I've run into a wall—none of them are giving me any readings. I tried three different ones, but when I perform an I2C scan, it shows no devices on the bus. It's a bit frustrating, and I'm starting to wonder if there's something I'm overlooking in the setup or connections. I did make sure to install pull-up resistors rated at 6.8K, so I thought that would suffice. However, I'm still not getting any response. Could there be some common issues that you're aware of or suggestions on what I might check next? Your insights would greatly help me troubleshoot this situation!
