Final Project Updates

Final Project Ideas

Create jellyfish (crochet) and either suspend from ceiling or create some sort of stand
have varying levels of movement based on inputs (buttons, switches, dials, rfid)
movements: move faster, change direction

Create a solar system (also crochet?)
inputs (rfid, button, dial, switch) spawn both movement and audio output that bring attention to and facts about different planets
maybe moves on track?

April 5th

What if….?

• able to change speed
• able to set off movement of specific ones (color sets?)
• change direction of movement (noticable?)

6 jellyfish in 3 colors
3 motors - each connect to 2 jellyfish
each motor moves for 30 seconds per trigger
etcentric cams ? pear shaped ?

need layers of interaction -

• toy ?
• unpredictability

buttons start movement of each set

• single button sets off movement of each, almost randomly ?
  • each press turns on/off each movement (variables?)
• knob ? allows control of speed

maybe need another axis of movement (idk how to do that)

possibly use light switches
different combinations of switches create different motion (speed, which move, etc)

April 19th update

created mostly working prototype that works without power
still need to cut gears to attach to motors/dowels
the arduino can power 20mA per pin and 100mA for the whole board
if adding capacitors, use .01-.1 uf capacitors
seperate power supply for motors (3-6V) making sure to connect grounds
ordered all parts, waiting on motors to arrive

April 21st update

recieved L293D motor driver shield

Information on shield:

• Motor Power Connections
  • shield supports motor voltage range of 4.5-25V
  • can be shared with arduino or powered seperately
  • remove pwr jumper to seperate power
  • only share power when the motor supply voltage is less than 12V
• DC Motor Connections
  • each channel can supply up to 600mA current to each motor
• Arduino Shield to Pin Connections
  • for DC and stepper - shield uses pins D3-D8, D11-D12
  • for servo - shield uses pins D9-D10
  • shield does not use pins D2 or D13

Apriil 22nd Update

Finally got motors in. Soldered wires to the motors, as well as soldered wires to the analog pinouts on the shield board to connect buttons to.
LOTS and LOTS of trial and error and testing for code, but finally have buttons working (mostly) to turn on/off each motor.
