Test Your Reaction!

by Anahit

Published on July 28, 2016

It is a tool for testing your reaction which gives you a score at the end.

You have 10 points to begin with when the test starts. The bargraph will fully light 10 times, randomly, and stay on for a short period of time. You have to press the button while the lights are on. You will get a point if you succeed. The servo will swing the flag attached to it indicating that you have caught it and the bargraph will show an animation.

You will lose a point every time you miss a light or if you press the button while the lights are off.

So your scores can go up to 20 if you don't miss any light, or go down to 0 if you miss all of the lights.

The tool supports 3 modes - easy, medium and hard. You can change the mode using the dimmer.

The results are printed in the Serial Monitor during the test. It will show the summary at the end.

Duration: 2 weeks

Mount the servo on the board using a mounting wire. Make a flag using a straw and sticky paper, then put on the head of the motor. Cut a round piece of cardboard, split it into 3 sectors and write "easy", "medium" and "hard" in each sector. Make a hole in the center and pull on the dimmer. Make an arrow from mounting wire as shown in the picture (between the button and the dimmer). Turn the dimmer clockwise all the way to the end, then hold the tip and rotate the cardbord until the arrow points to the beginning of the "easy section". Fix it cardbord on the dimmer so it doesn't move.

STEP 3 : Run it!

Turn the board ON, configure the COM port and open the Serial Monitor. You have to accomplish it in 15sec in order to not miss the welcome screen. If you miss it, you can turn the board off/on and start over again. After you see the welcome screen, you have to send the character 'n' and the test will start. You can send 'n' even if you miss the welcome screen - it will still work fine.
