Hey guys! I'm currently working on a project that requires me to control a servo over a cable that is longer than the usual 10-15 cm jumper wires.. In fact I'm using a 20m long cable to access the servo I need to control and there is absolutely no other way than using the 20m. Now the problem is that the servo will work properly when attached with short cables but will go totally nuts with the long one. I figured out that it was due to a voltage drop, so I tried hooking it up to an extern power source that is more powerful. This seems to work partially because my multimeter is now showing 5V(needed) at the end of the cable but as i can't put more voltage through the pwm pin the servo isn't moving..
Any ideas? any possibility to make the pwm signal stronger?
