E Ink QR Generator Arduino BLE and LTE Updates
Budget: $250 – $750 USD
Need to have an E Ink screen be updated with QR codes that can be generated from something like qr.io (would prefer to use internal QR generator if possible) and have that QR code be displayed on the E ink screen. LTE Hat for the Arduino for updates over cellular and BLE for the times that cellular signal is not available as a backup.
