Week 3 Objectives:

Objective A:    – Build RGB LED 2 Circuit

Objective B:    – Build 7 Segment 2 Circuit

Objective C:    – Build Potentiometer 1 Circuit

components needed:

1x 2AAA battery pack
1x Breadboard
5x Male-Male Wire
1x RGB LED
1x 220 Ohm resistor

Objective A: Build this circuit!

When you’re done: all three colors of the RGB should light up. Try out different combinations by unplugging one or two colors! Remember that the longest leg is the common negative leg and the red leg will need a 220 resistor.

components needed:

1x 2AAA battery pack
1x Breadboard
7x Male-Male Wire
1x 7 Segment LED
1x 220 Ohm resistor

Objective B: Build this circuit!

When you’re done: the 7 segment LED should display a capital E. Try different combinations of pins to create different letters and numbers! Remember that the top and bottom middle pins are the common pins to negative. Only one of these pins needs to be connected.

components needed:

1x 2AAA battery pack
1x Breadboard
5x Male-Male Wire
1x Green LED
1x Potentiometer

Objective C: Build this circuit!

When you’re done: turning the knob on the potentiometer should control the brightness of the LED.
