What can I make?

Some people have asked: What gizmos, games and tools can you make with the Grandpa's Gizmos course? The list is below, and keep in mind that as additional gizmos are made using new sensor types, they will be posted as bonus lessons. (Oh, and you cannot create the AI image of a light sabre above -- this is just a bit of humor)

Games

Stop It game -- press the button when the correct LED is lit

Grandpa Says game -- repeat the pattern of sound and lights

Pong game -- Arduino port

Broken Arrow game -- Find the nuclear bomb

Space Trash game -- shoot the trash

Fortune Teller game -- think Magic 8 Ball...

Landing Simulator game -- Land spacecraft with wind effects

Gizmos

Continuity tester -- test your solder joints

“Northern Lights” Psychedelic Night Light -- Art meets science

Ghost (emf) detector -- oooh, scary!

Night Light with buttons -- Improve night light

Strobe light -- Adjustable frequency strobe light

Racing Splits Timer -- saves a table of lap times

Night Light with beep feedback -- Improve night light user interface

Melody player -- from sheet music to Arduino!

Clock nightlight -- Add a clock to the night light

Metronome -- Adjustable metronome with display options and light flash

Clock with auto-dimmer -- improve the clock by controlling display brightness

Optical Theremin -- A different take on the theremin sound used in the Star Trek series

Clock with temperature display -- add ambient temperature display to the clock

Reaction time measurement device -- press button as soon as LED turns on, table of stats

Graphing thermometer -- keeps track of 24 hours of temperature, graphs, zooming

Entrance counter -- counts the number of times the light beam is broken, optional chime

Workout Timer -- switch between up to 6 timed routines

Complete psychedelic nightlight alarm clock with temperature display and clock sounds and…?

Demos

Button delay demo -- test different ways of debouncing buttons

Four digit 7 segment display -- experiment with display modes

Rotary encoder demo -- test different read modes

OLED Graphics display demo -- experiment with display modes

OLED Text display demo -- use of fonts and text positioning

First bonus lesson

The first bonus project has already been posted. This lesson teaches about measuring moisture in soil and you make a handheld plant soil moisture sensor. (The sensor is available on Amazon).
