Sounds interesting! If I may ask out of curiosity:
Why OLED?
Why this QR thing and not Bluetooth, or is it both?
Is it storing long-term data or just while battery is on?
- HTresearch 4y agoOLED is the cheapest display with enough resolution. No Bluetooth. A previous version had it, but the development effort was much higher, given it then needed an App also. I wanted something simple for say a school teacher to report values in their classroom. Data is not stored long term currently. Just since last power on.
