Arduino ShakeIt Wind simulation
This article is just an example using a Motor shield board, Other options are available here : https://github.com/zegreatclan/SimHub/wiki/Arduino-Shake-It
- Arduino uno
- Adafruit Motor shield v2
- 12V 3 pin fan(s)
- 12V power source
Estimated Cost : For one fan : Arduino UNO clone 5€ + Shield 6€ + 12v power brick (recycling) + Fan (5€) = 15€ For two fan : Arduino UNO clone 5€ + Shield 6€ + 12v power brick (recycling) + Fan (5€) = 20€
Adafruit motor shield V2 is rated for 1.7A (up to 3Amps peak). For high power fans like boat blowers, you may want to use a Monster moto shield instead of a Motor shield v2 : https://github.com/zegreatclan/SimHub/wiki/Arduino-Shake-It#monster-moto-shield
- DC control will trigger some high pitched noise, it's possible to change that pitch to a less hear sensitive value : https://github.com/SHWotever/SimHub/wiki/Arduino-Shake-It#about-motor-shield-v2-humming-noise
- Alternatively you can go for PWM fans see : https://github.com/SHWotever/SimHub/wiki/Arduino-Shake-It#pwm-fans
- 3d Printed Fan shroud support (https://www.thingiverse.com/thing:2884277)
For this wiring, you need to identify the GND and 12v pins of the fan, don't trust the colour codes to identify the 12v pin, please refer to the connector, GND is usually black hopefully :
- You can plug more fans by using the other outputs (M2/M3/M4).
- Always check board outputs polarity with a voltmeter, these shields are not +/- labelled, so you may need to swap +12v and gnd based on the measurement.
Stack the shield to the arduino, and plug the 12v power source to the DC barrel jack of the arduino
