Challenges and Improvement

The most challenging aspect during the process was connecting the Force-Sensitive Resistor. I was surprised to find that one end of the Force-Sensitive Resistor is connected to both the A2 pin and an additional resistor. Some possible improvements could include adding another button so that users can cancel the SOS signal if triggered accidentally. Alternatively, I could swap the button with a switch so that users do not have to press the button repeatedly (until they are noticed) but instead can turn the switch on/off.
