Integrating Solar Power

Grades:
9-12
Lesson Number:
5
Description:
At this point students should have a working robotic sunflower that will track the sun with 2 degrees of freedom. This next lesson powers the whole system with a photovoltaic module. A Zener diode is used to charge a 6V motorcycle battery which then supplies...

Dual Axis Light Tracking

Grades:
9-12
Lesson Number:
4
Description:
Students will take the previous lesson and apply them in creating a light tracker with two degrees of freedom. The axis of rotation will be about the horizontal and vertical. Teams will have everything they need to make this build work. They have already...

Creating a Light-Tracking Servo

Grades:
9-12
Lesson Number:
3
Description:
Students will learn how to program the Basic Stamp to use information from two photoresistors to point a servo at a light source. This will be the first degree of freedom for the flower head.

Controlling a Servo

Grades:
9-12
Lesson Number:
2
Description:
In this lesson students will learn how to control a servo using the Basic Stamp. Then students will combine the photoresistor from the previous lesson with the servo to create a light controlled servo.

Measuring Voltage Using a Microcontroller

Grades:
9-12
Lesson Number:
1
Description:
In this lesson students will be introduced to series circuits, resistors, a photoresistor and a microcontroller. There’s a lot here, but it boils down to making a voltage divider circuit and measuring the voltage at different points. A second circuit includes...

Learning Goal(s):
Students will apply Ohm’s Law. Students will use a multimeter to measure current, voltage, and resistance. Students will use a breadboard to set up a series circuit. Students will read circuit diagrams. Students will calculate times for an RC circuit to change state. Students will prove that resistors in series have an equivalent resistance equal to their individual sums. Students will program the Basic Stamp to measure voltage levels in a voltage divider and RC circuit.
