Lab 6

Project Members: 


I created a fan that spins with input from the pressure sensor. It can spin fast or slow, depending on how hard you press down. Woot!

Tape and cool paper

int FSRPin = 0; // select the input pin for the potentiometer
int motorPin = 9; // select the pin for the Motor
int val = 0; // variable to store the value coming from the sensor
void setup() {
void loop() {
val = analogRead(FSRPin); // read the value from the sensor, between 0 - 1024
analogWrite(motorPin, val/4); // analogWrite can be between 0-255




Comments from TAs

Cool fan (literally!). Squeezing a fan to speed it up is an interesting interaction. It would be good to think about what kind of physical form might mesh well with such a fan. For example, would you have a spring-loaded handle that could be squeezed to turn on the fan? After you squeezed, would the fan stay on, or would you have to keep squeezing (and potentially get tired)? Now that building things with Arduino is getting easier, it's important to think about these other issues.
