Take our Daughters and Sons to Work Day June 2024
At work we are having a take a child to work day and I will be running an Arduino table with a target age range of 9-16 and a time range for each group of one hour.
See https://github.com/Mark-MDO47/TODAS_DaughtersAndSons/blob/master/TODAS_DaughtersAndSons.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
- Graduation Caps - https://github.com/Mark-MDO47/GraduationCap2017
- Version 0.1 of the Halloween Skull with Eyeballs - https://github.com/Mark-MDO47/HalloweenEyes
- Voice controlled Christmas tree lights - https://github.com/Mark-MDO47/ArduinoClass/blob/master/FablabChristmasArduinoTable_2023.pdf
