Wind Simulator HELP!!

Post by Aschloffel »

I am trying to build a Wind Simulator for my racing sim. I have the Arduino Uno R3, and ADAFRUIT Motor shield V2.3. I am using Sim Hub to control everything. There are a couple videos on YouTube explaining how to do this project and feel like I followed them, but I just cant seem to get it to work...

How its set up...
The motor shield is stacked on top of the Arduino with a 12V/3A power supply connected to the motor shield (I had it connected to the Arduino but was told to try and connect it directly to the motor shield). Fan is connected to the M1 connector and have tried this on m2-m4 as well with same result. I get 12V to the power connector on the motor shield, 12V to the M1-M4 connectors (with and without fans connected) but when I click Test in Simhub the fans don't spin at all. I used the Motor shield V2 sketch in Simhub and all seems to be connected properly with the channel 1 and 2 turned on and 100% gain . I am using the Arctic p12 with a 4 pin connector/4 wires. I am not sure if I'm doing something wrong or missed a step but I'm stumped. Any and all help would be much appreciated!!

Have you tried an example Arduino code? Can you post pictures of your setup for clarity?

So I ran the DCMotorTest... I can hear the fan making a high pitch whine but it is not spinning. I tried to spin it to see if it would keep spinning but it did not. I know the Noctua fans run a 3 phase motor and I'm wondering if the Arctic p12's also have a 3 phase motor. Can the motor shield handle over a 1 phase?

Variable-speed computer fans use brushless DC motors - typically 3-phase. But the controller is built into the fan. You need to supply it with a DC voltage, and a separate PWM control signal at 25KHz.

You can use the motor shield to supply the DC voltage if you set the speed to 255 (100% duty cycle). But the PWM frequency of the shield is 1.6KHz max - so not fast enough to do the speed control.

The EMC2101 is a better choice for computer fan control: https://www.adafruit.com/product/4808
