Assignment: DC Motor: Actuation Assignment 1
Collaborators:
See "deadplant" attachment for a photo of what happened to my last plant.
It died, and now I"m worried I'll have no more luck and get caught in an earthquake.
Thus, for my TUI assignment this week I created a plant rotator which rotates the plant. Ie. a lazy susan for plants. Of course it could be used as a lazy susan but my apartment is so small I have no need for a table, much less a table accessory.
Materials used:
cardboard
tape
battery holder
2 AA batteries
wires
transitor
breadboard
arduino
10k resister
diode

//I wanted to just rotate the dc motor half a circle but couldn't figure out the correct timing to get it to work but htat
//val = analogRead(potPin); // read the value from the sensor, between 0 - 1024
//static unsigned long lastTick = 0; // set up a local variable to hold the last time we moved forward one second
// move forward one second every 1000 milliseconds
//if (millis() - lastTick >= 1000) {

//if (second - lastTick >= 60) {

//this is where I didn't know by how much to rotate the motor -- 100sec? I couldn't figure out the speed of the dc motor.
//timer=0;
//while timer<100

//Serial.println(val);
//so instead I just continually rotate it very slowly
analogWrite(ledPin, 30); // analogWrite can be between 0-255
//it did not work well at low levels. this was as low as it could really go.
