Intention

Try to imagine a simple three component sensing device (an LED, a sensor and one additional sensor)

Process

It is very hard to connect two sensors together on the breadboard at first. Because I connected these two as series circuits at first, so it didn't work for a long time, I searched a lot about Arduino circuits to find the solution to achieve this successfully. And I tried to add the piezo but there is not enough space on a single breadboard, so I just tried to write the code to control it and then // them. And I will try after I get another breadboard.

Reflection

I think combining the bend sensor and force sensor may can be a prototype of the wearable device for finger bending recovery, when the injured finger bends a lot (will be limited in a range based on the Heathcare knowledge) or be pressed a lot which will aggravate the injury, the alert will remind people of taking care of their injured fingers. I think this direction can be my improvement direction in the future.

Condition 1: When the bend sensor is over bending and press sensor is pressed a lot, the piezo’s sound alert will start, and the LED will blink for 1.5s.

Condition 2: When only the bend sensor is over bending, the piezo’s sound alert will start for a short time, and the LED will blink for 0.5s.

Condition 3: When only press sensor is pressed a lot, the piezo’s sound alert will start for a short time, and the LED will blink for 1s.

Condition 4: When nothing on the press sensor and bend sensor, the LED and will piezo’s sound alert keep off.

(Only code about piezo and I will try it on breadboard when I get another breadboard)
