 All right, Lena, what is this? Okay, so I put together the prototypes for my macro pad with all those LEDs and buttons and the OLED socket and everything. And then I got home and it's time to actually put it to the test. So this is some Arduino code running on it that you can see it reacts to when key presses are pressed. I can press them all, there you go. There's also the rotary encoder which you can see as I turn it, it goes the right direction and when I press it, it also knows it was pressed. And then finally, I'm doing a little I squared C scan with a STEMI QT sensor. So you can see here when I have it plugged in it says there's something detected when I remove it. It's like there's nothing detected. So this is my little hardware bring up test. But so far so good, I have a couple tweaks to do. Like, you know, it's a little embarrassing but I actually had to add a couple of 10 micro far capacitors. I needed more capacitance, but I think it's almost done.
