The schematic above and to the left shows the set up for the Bluetooth HC05 module and an Arduino board. The tx pin on the bluetooth requires a 3.3V logic which is where the voltage divider comes from. The RX pin must connect to a TX pin and vice versa.
The schematic below corresponds to a simple voltage divider. The FSR is the force sensor, which changes its resistance based on the pressure applied. The corresponding code uploaded on the Arduino is able to take the analog reading and convert the voltage into a Force.
