Measuring Voltage Using a Microcontroller

Grades:

9-12

Unit:

Lesson Number:

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.

Learning Goal(s):

1.Students will identify all ways that energy is consumed within their homes.2.Students will perform an energy audit of their home and calculate the amount of energy used by each electronic device and appliances.3.Students will create a spreadsheet demonstrating the electricity required to operate each electronic device and appliance, along with a summary of finding that clearly identifies how energy consumption can be reduced within their home.4.Students will explore various ways to reduce energy (goal is 30% reduction).5.Students will propose a variety of energy reduction plans and present those options to their families for discussion.6.After discussion with their families, students will itemize the agreed upon plan and identify specific actions that result in quantifiable outcomes that will implemented to reduce energy consumption by their families.
