I am posting this problem looking for advice.
I am running Arduino Nano code which gives random movement for 3 servos +1 DC motor.
When the Arduino is powered by the laptop USB, everything works fine..but when I disconnect from laptop and power it from a battery; the sketch behaves strange because motion for all servos happen at 1 second interval all the time...I reconnect to laptop USB again it works fine again...I connect to battery it behaves strange...any reason please ? The battery is 2 laptop cells delivering 2 x 3.8 = 7.6 Volt t@ 2000 mAH to the servo shield.:-(
