  3. excitation emission Fluorescein Detection detection well Acrylic chip blue LED photodetector

  4. Schematic

  5. TASK 1 - Check the Breadboard Setup Connect to 5 v. Power Supply Measure the Power Supply Voltage, V = ______ Volts +5V Short wire Ground

  6. TASK 2 - Binary Voltmeter Circuit • Insert Binary Voltmeter Board • Insert eight LEDs • Connect Gndon Binary Voltmeter Board to Ground on Breadboard. • Connect the DMM Positive wire to V Input • Connect a wire from Vinput first to +5 Volts and then to Ground. Verify all LEDs turn on and off respectively. LED short wire on this side, negative terminal connected to ground

  7. TASK 3 – Binary Voltmeter Calibration Circuit • Place the TrimPot as shown and: • Connect Pin 1 to Ground • Connect Pin 3 to +5 V • Connect Pin 2 to V Input on the Binary Voltmeter +5V Ground
