Hi Guys,I need a lot of help with the servos.I made something similar to robo arm that uses 4 servos.I tried to use the arduino power and it was working, but I was having problems with the usb so I decided to use external power supply.The supply has no load voltage-9 and description 3.7V at 375mA
However does anybody have an idea why if I connect one servo to my arduino and use the arduino power to supply it its working.When I use my multimeter to meassure the current the problems are starting again?I use relative good multimeter so the resistance should be really small and shouldn't change anything on the circuit
