Mbot & feetech servo


#1

Hi everyone, I recently purchased a feetech servo ( FR5113M) for my mbot but I can’t make it work properly.
Equipment : mCore board; 2 standard dc motors, 8 AA nimh 1.2V battery (2400 mAh & 2000 mAh); wifi module; Me RJ25 Adapter and Feetech FR5113M servo.

I plugged everything as ou can see in the picture but it only worked for a day and the battery were not fully charged so I don’t think it’s a battery issue. The 2 dc motors works fine but the servo don’t, even if I hear clicks inside and I see it move a tiny bit. Sorry for my bad English I’m French
.

I have just tested it again with the same battery and the same code but with a multiplex servo tiger digi 4 instead and it works. But the torque and the holding power of this servo are too low for my project. So I need to make the feetech work.

the servo is no problem,
There is problem for your power supply,
The servo need direct power supply from battery,
But you don’t make it.
