Solar Energy Lab 1ENGR 1181
Today's Learning Objectives
After today's class, students will be able to:• Describe and build both a calibration and solar meter
circuit • Convert a binary number to a decimal value• Discuss how a potentiometer works • Explain how a photodiode light sensor works• Given a schematic drawing, build a working electronic
circuit on a breadboard • Use a Photodiode Light Sensor and a Binary Voltmeter
circuit to measure the intensity of light (in Watts/m2)
Solar Energy MeterIn lab today, you will build a solar energy meter circuit to measure the energy intensity from a light source.

Trimpot – variable voltage Total resistance (Pin 1 to Pin 3) = 10 kOhms Resistance at Pin 2 varies by turning the adjustment knob
Produces Vadj output voltage of 0 to +5 Volts on Pin 2
It is a variable resistor

8-Bit Binary Display
• The LEDs at the output of the Binary Voltmeter are labeled from D7 to D0
• The LEDs are either "ON" or "OFF" – for binary numbers "1" and "0"
• D7 is the Most Significant Bit (MSB) and D0 is the Least Significant Bit (LSB)
• Any 8-bit binary number can be converted to a decimal number
