next hand held game controller. Your next task is to develop a proof of concept for the
reaction timer test.
The solution you will build and test in this activity is an example of how to solve this
problem, but it’s definitely not the only solution. Before continuing, take a moment to
think about how you would design this reaction timer.
Reaction Timer Game Parts
(1) LED – bi-color
(1) Resistor – 470 Ω (yellow-violet-brown)
(1) Pushbutton – normally open
(1) Resistor – 10 kΩ (brown-black-orange)
(1) Resistor – 220 Ω (red-red-brown)
(2) Jumper wires
Building the Reaction Timer Circuit
Figure 3-14 shows a schematic and wiring diagram for a circuit that can be used with the
BASIC Stamp to make a reaction timer game.

Build the circuit shown in Figure 3-14.
Run TestBiColorLED.bs2 from Chapter #2, Activity #5 to test the bi-color
LED circuit and make sure your wiring is correct.
