Hello,
How to use the Inventor app to receive data from a camera connected to Arduino via Bluetooth and display the image on the screen? please help.
I think you should first make sure that your Arduino is set up to capture images and send them over Bluetooth and in the MIT App Inventor, create an app with Bluetooth connectivity to communicate with your Arduino.
Use the Bluetooth component to establish a connection and receive the image data and implement a method to interpret the data received from Arduino and display it on the screen, possibly using the Image component. You may also need to convert the data into a format compatible with displaying images.
