Inky:bit, an electronic paper for micro:bit, is a display that remains on display even when the power is turned off. Therefore, it can be used in a variety of ways, but if you can't master the micro:bit programming, you won't be able to perform to its full potential. Even if you want to display images such as illustrations and handwritten characters, micro:bit alone is not enough. Therefore, we made it possible to transfer the illustrations and characters drawn on the iPhone or iPad as image data with this app. The micro:bit and iPhone communicate via Bluetooth. Before use, you need to pair the iPhone (iPad) and micro:bit via Bluetooth. Usage 1. Pair your micro:bit with your iPhone via Bluetooth. Pairing can be done with the micro:bit app. 2. Launch the microbitINKY app and press the "micro:bit CONNECT" button. When connected, the "UPLOAD" button will be enabled. 3. Draw characters or illustrations and press the "UPLOAD" button. 4. When the transfer is finished, the micro:bit will process it for a while and display it. Once written, the picture will not disappear even if the power is turned off. The "CLEAR" button clears the micro:bit display and screen display. Press "micro:bit DISCONNECT" to end the connection with the micro:bit.
