Are You Faster Than The Flash?

Project Steps Project ScheduleUnderstand The Project• Learn about Arduino• Study build instructions

Generate A Modification• Add The Flash theme

for aesthetic• Add superhero

comparisons to the code

Build Reaction Time Tester• Order all parts• Assemble wiring• Modify and upload code• Make and paint a box• Solder wiring• Fully assemble

• Two main types of LCDs: large display & small character• Potentiometers can control brightness or contrast• Two factors influence LCD contrast: driving voltage &

temperature • Potentiometer controls driving voltage• Compensate for temperature variation with potentiometer

How it applies• Reaction time shown on LCD in

milliseconds• Potentiometer used to change

screen contrast• Fun sayings appear on LCD

screen

Concept History• Liquid Crystallinity first observed by Friedrich Reinitzer, LCs extracted from carrots• First LCD made by RCA 1964• LCDs used in Japanese manufacturing during 1970s• First LCD TVs created- 1990s

Engineering Concept- LCD Potentiometer Pairing
