I’m making an air quality detecting device. I have a gas sensor that can detect a wide range of gases that is hooked up to the 5V port on my Arduino Uno. I’m adding a Bluetooth Module for sending data to an app. Can I use the 3.3V port on the Arduino to power the Bluetooth module instead of using voltage dividers? If I still need to use voltage dividers, have I set them up correctly (see attached photos)? The resistor values are 1K and 2K. My setup is exactly as according to this video VIDEO
- This is the Bluetooth Module I bought Bluetooth Module
Thank you so much! I need to finish this project by the end of the week.
