Hello there,

It's my first attempt with Arduino and simhub and I'm struggling with my setup because fans dont spin at all : 

- Arduino UNO R3 genuine

- Dallotek Motorshield V2

- 2 DC FAN 12v 1.44w 0.12A

- 1 DC 12v power supply 1000mA connected in the motorshield

 

First, my Arduino had a default. The sketch upload was impossible. After a test on another PC, re-order a new one which works.

Second, the fans didnt spin because I had PWM Fans. So I have ordered DC Fans. Now, the setup seems OK but fans dont spin at all.

 

Now, this is all the the tests I have done to identify the problem : 

- The Arduino is configured with the right board Arduino Uno and motorshield V2, detected on COM5 (I have also tried with COM9)

- The Arduino is recognized in Sim Hub

- Gain is 100%

- Speed is activated with default settings at 100%

- Motors 1 & 2 (I have tried 3 & 4) are activated in simhub

- When I click "test", the graph is OK at 100%

- There are 12V on the screws of the power supply on the motorshield (voltmeter), polarity is OK

- Polarity for the fan connection is OK with a Voltmeter

- Fans spin when directly connected to the 12v power supply 

 

My questions (sorry if noob question) : 

- There are constantly 12v on the screws for each fan, normal ?

- The led on the motorshield is RED when power supply is connected, normal ? 

- What can I control ?

 

Thanks for your help,

 

Regards,

 

Guillaume frome France

Hello Guillaume, I'm in the exact  same situation, my fans actually worked a few months ago with the old shakeit motors set up (rather than the shakeit wind) but don't now. I've tested the fans with an Arduino sketch I wrote and uploaded myself, and they worked properly, but they don't seem to run at all in Simhub (when pressing the test button or in-game). Have you found a solution since your post?

Same here. I also had all the test you did. In addition, I tried 12V-2A, 12V-6A and 12V-8A adapters and replaced the motor shield with 3 different clones but the fans are still not spinning.

I have two 12V DC-1.40A, 36W, 4000 RPM but since they didn't work, I tried a low power, 6mm old fan (not sure about the specs), but it didn't work either. They are connected on M1 and M3.

Any suggestion would be appreciated.

After checking all available content and testing the ports of the motor shield with a multimeter. Obviously, there is a code issue. I guess it doesn't work because the sketch cannot communicate with the L293D motor shield. I found only one Adafruit Motor Shield v2 available on the Diigiit Robotics (France but ships worldwide). I will test if it works as soon as I receive the unit and update the post.

Hello all, I managed to get my fans going. My first issue was that I had incorrectly selected the SHAKEIT Adafruit Motorshield V2 rather than the SHAKEIT DK Motor Shield, then I still could only operate one fan, so I plugged the second fan into input 3, instead of using M2 and now everything seems to be working. Hope this helps.

Great to hear that it works for you. My new motor shield arrived an hour ago and sitting on the table. I will share updates if anything changes. And yes, I also bought Adafruit Motor Shield V2.

After replacing the L293D motor shield with the adafruit motor shield v2, fans and motors are working very well.
