I am trying to revive an old RC. My implementation is this
Power 2x3.7 Lipo to Drive the L9110 Motor driver 1x3.7 Lipo to Drive Pro mini & the IC2262/2272 Radio 4 Channel
Hardware RC = http://www.ebay.com.au/itm/281212808317?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 Arduino Nano = http://www.ebay.com.au/itm/111227635175?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 An Old RC - Powered by 4xAA battery L9110 H Bridge Driver = http://www.ebay.com.au/itm/L9110S-H-bridge-Dual-DC-Stepper-Motor-Driver-Controller-Board-for-Arduino-New-/400576054198?pt=AU_B_I_Electrical_Test_Equipment&hash=item5d443183b6
What's weird is that, whenever I put load on the motor it jitters for a few second then starts to pick the speed.
Here's the video of the problem. I will post the schematic soon, it's really simple circuit.
Any help would be very much appreciated.. Cheers!
