Can’t seem to get my TowerPro SG90 servos working. They tick, sometimes move, sometimes not – it’s wierd.
Please advise!October 30, 2015 at 12:00 pm #2840
Once the program has ended, the Crumble then goes into ‘stopped’ mode. So, a program with a single servo instruction would create a kind of tick.
If this is the case, could you try and put a wait command after the servo block?
All the best,

Code is same as yours – that you tweeted. Just checking rest of circuit…October 30, 2015 at 12:10 pm #2842
Gosh Darnit – it was a defective battery! All working now!
Thank you for a FAB new update and super quick support!

Have had good fun today getting to know Crumble but now stuck with servo use.
I am wondering if I can use small a TowerPro SG90 servo
Have looked but cannot find any help giving connections and test code
Please could you direct me to suitable instructions
Thanks in anticipation

The servos have three connections, two for power and one signal/control line. Simply connect the power to + and – on the Crumble, and connect the signal to A, B, C or D (you can connect up to 4 servos).
The wire colours vary, but I believe the SG90 is:
I’ve attached a simple program that should test the servo (on A). One thing to be aware of is that when a program finishes, the Crumble stops outputting the signal to the servo. The attached program is looped, so never ends.
I hope this helps.

Thanks for your help and servo code
It works well with the cheap tower pro servo
and also with a larger 360 degree servo.
Now my favourite for educationNovember 25, 2015 at 1:14 pm #3011
Many thanks 🙂
