Hi I'm Seth.
For my midterm project, I created a tilt sensing motor. I made two tilt sensors out of ball bearings and bic pens and positioned them on either side of the motor at different angles. When the motor/device is tilted in one direction, it will spin clockwise, and when tilted the other direction, counter-clockwise. Originally I wanted to control a toy that would fall over and correct itself, but the motor it used takes a little more power than I was able to supply directly from the microprocessor, so this might be considered to be a prototype. As for the aesthetic of the device, it would be fitted to the duty it was designed to perform such as a handle for a fishing pole, etc. For testing, I affixed the components to a toilet paper tube with the tilt sensors pointing up a little bit so that they won't always be triggering.
(I let my friend borrow my Arduino, so there aren't any pictures of the "device" as a whole, but here are the main components!)
And Here's the code!
int turn1 = 12; // choose the pins for controlling direction
int turn2 = 13;
int tilt1 = 4; // choose the input pin (for the tilt sensors)
int tilt2 = 5;
int val1 = 0; // variable for reading the pin status
int val2 = 0;
void setup() {
pinMode(turn1, OUTPUT); // declare turn pins as output
pinMode(turn2, OUTPUT);
pinMode(tilt1, INPUT); // declare tilt sensors as input
pinMode(tilt2, INPUT);
digitalWrite(0,HIGH); // write a HIGH to allow for current to flow through pin
digitalWrite(1,HIGH);
} void loop(){ val1 = digitalRead(tilt1); // read input value val2 = digitalRead(tilt2); if (val1 == HIGH) { // if tilted, turn the motor! pinMode(turn1,OUTPUT); // turn the pins on pinMode(turn2,OUTPUT); digitalWrite(turn1, LOW); // turn the motor! digitalWrite(turn2, HIGH); } if (val2 == HIGH) { // if tilted, turn the motor! pinMode(turn1,OUTPUT); // turn the pins on pinMode(turn2,OUTPUT); digitalWrite(turn1, HIGH); // turn the motor the other way! digitalWrite(turn2, LOW); } if(val1 != HIGH && val2 != HIGH){ // if it's not tilted either way pinMode(turn1,INPUT); // turn the output pins "off" pinMode(turn2,INPUT); } }
