Review
From Our previous classes:
Sensors: measure the environment
Actuators: affect the environment
End Effectors: interact with the environment
CPU: Central Processing Unit, a.k.a. the brains
Infra Red Light: Invisible light with lower frequency
Task: in the above pictures, circle a sensor, an actuator, an end effector, and infrared remote control.

Program your Robot
Task: program your robot to use the infrared sensor as control input.Task: do closed loop control using your brain as a CPU.

Electromagnetic Spectrum
Electromagnetic radiation:
produced by different processes detected in different sensors.
Electromagnetic radiation such as visible light and infrared radiation can be expressed in terms of energy, wavelength, or frequency.

Our First Program
Program your robot to read the ambient light sensor
Task: shine a light onto the ambient light sensor, record the sensor readingTask: repeat the above task with a different amount of light shining on the sensor.Task: read the time measurements and tabulate them below
Task: program your robot with your desired top speed, and let it race!
