Presentation Transcript

- Voltage tells us how hard a positive charge ispushedbetween two different points.
- Something, such as a battery, is needed to createa voltage.

Current, I

- Current tells us the amount of chargeflowing throughsomething (similar to gallons per minute).
- Current must have a path through which to flow.

I = V / R

Resistor:

R

V = 5, R = 5, I = ?

- Voltage at wiper depends onposition along the resistor.
- Voltage varies between ground(0V) and the supplied voltage(5V in this case).
- Voltage various continuously(analog “signal”).

WIPER

Conversion of Analog to Digital

- Obtain “analog” input using analogRead().
- analogRead()returns a value between 0 (if pin at ground) and 1023 (if pin at 3.3 V).
- Argument of analogRead()is the pin to read(only pins labeled ANALOGIN can be used).
- Servo position varies between 0 and 180.Therefore, must divide analogRead()whatreturns by 5.68333 (1023 / 5.68333 = 180).
