Basic Stamp Microprocessor

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.

Simple Solar Water Heater

Making the Standard Solar Heater

Grades:
6-8
Lesson Number:
1
Description:
In part one of the activity students will be asked to create a simple solar heater, measure the temperature change in a vial of water, then calculate the heat energy transferred to a vial of water. Students will construct the solar heater, place a set amount...
