Basic Project Information

Modification

• Reaction time tester• Uses an Arduino Uno circuit board

containing a microcontroller• Flashes a red, green, blue LED light• Sounds a random buzzer• Displays reaction time in milliseconds on

LCD screen

• Themed after The Flash for a nice aesthetic

• Code displays super hero reaction time comparisons based on actual reaction time

• Solutions:• Bought correct parts• Fixed code to correctly display

• Learned about:• Arduino• Gantt Chart• Shop Skills• Time Management

• Fun and interactive hand-held game

• Paint job modeled after The Flash

• Reaction time compared to a superhero

Discussion and Conclusion

(Humphrey, 2015)

Calculations Potentiometer vs. Screen Contrast• There is a direct relationship between LCD

driving voltage and contrast

• 𝑉driveLCD = (220ohm) (220ohm+ pot) (5v)𝑅

• (VdriveLCD/5v) 1023 [conversion]=Flinear

• Every 10% of Flinear equals 10% contrast
