Circuit Documentation
Summary of the Circuit
This circuit is designed around the ESP32 Wroom Dev Kit, which serves as the central processing unit. The circuit includes a Force Sensing Resistor (FSR) that allows for pressure sensing capabilities. A resistor is used to create a voltage divider with the FSR, which enables the ESP32 to read analog values corresponding to the force applied to the FSR. The ESP32 is powered by its 3V3 pin, and the FSR's signal is read through one of the ESP32's GPIO pins. The ground connection is shared between the ESP32 and the FSR to complete the circuit.
