Need help to find the proper Arduino card for my squeeze ball project

Hello,

For a project i'm working on i need to insert a pressure sensor inside a squeeze ball. The sensor should send the pressure to a PC. I already got this working with a pressure sensor inside the ball, connected to the Arduino which is connected to the PC.

I would like to make this ball controller wireless using Bluetooth / WiFi. Is there any Arduino board / other board i can use which is small enough to work with batteries and inserted into an a squeeze ball that can fit in a hand?

Thank you ! :slight_smile:

One likely candidate is not and Arduino board, but a board that can be programmed using the Arduino IDE. This would any of the ESP32 boards or ESP8266 boards.
