BAC2WD_ArduinoExperience

Bring a Child to Work Day June 2024

• Previously "Take our Daughters and Sons to Work Day"

At work we are having a bring a child to work day and I will be running an Arduino Experience table with a target age range of 9-16 and a time range for each group of one hour.

03 Sonar Control	04 Banana Piano

See https://github.com/Mark-MDO47/TODAS_DaughtersAndSons/blob/master/BAC2WD_ArduinoExperience.pdf for details

My initial plan is

• use Arduinos and breadboards
  • have them do some of the connections
  • allow them to direct me in programming using three laptops
  • material contains some depth for those that are more advanced
• focus on switching things off and on
• inputs:
  • switches
  • buttons
  • ultrasound distance sensor
  • capacitive sensing - banana piano!
• outputs:
  • LED
  • WS-2812B LEDs and FastLed
  • speaker and YX5200/DFPlayer
• show Fritzing diagrams and schematics
  • explain switch sensing using water-flow analogy
  • advanced - explain capacitive switch sensing using water-flow analogy
• have some other arduino projects to show, such as
  • Persistence of Vision - https://github.com/Mark-MDO47/ArduinoClass/tree/master/02_PersistenceOfVision
  • Rubber Band Gun - https://github.com/Mark-MDO47/RubberBandGun
  • Version 0.1 of the Halloween Skull with Eyeballs - https://github.com/Mark-MDO47/HalloweenEyes
