Week 6 Objectives:
Objective B: – Add directional LEDs to your robot
Objective C: – Participate in a relay race
1x 7 Segment LED
5x Male-male wire
1x 220 Ohm resistor
Objective A: 7 Segment Circuit
Add a 7 Segment LED to your breadboard to display a letter or number. The 7 Segment shown in the diagram below will display an uppercase ‘E’, but you can change the wiring around to display a character of your choosing. Experiment!
4x Male-female wire
2x 220 Ohm resistor
Objective B: Direction LEDs
Add 2 LEDs to your DPDT switch so that one lights up when your robot is going forwards and the other lights up when it is going backwards. Because your robot uses a 6 volt battery pack, both LEDS will need resistors even if you are using colors other than red.

Objective C: Race time!
Find a classmate to race against! Whose robot will be the first to make it to the other side of the room and back? Or challenge yourself at home – how many times can your robot go back and forth without getting stuck?
