Hi I am a novice so please take it easy on me.
I am building a hexapod that has 12 servo motors all these 12 servo motors are to be controlled by my Arduino Mega. I have already learnt how to control servo motor with a controller like arduino and was able to control multiple servos (4 servos) simultaneously using the Arduino. I was able to crack the programming and now I am confident to control about writing the program to control all my 12 servo motors, but confused on designing the hardware part for it. All my knowledge on servo motors comes from this servo motors basics article and if I understood correctly every servo will consume different current based on the load applied to it. And the starting current and operating current values should be mentioned on the datasheet.
I am using the SG92R servo motors from adafruit. But I am not sure how much current my servo will consume when I am all 12 motors are operating. I might be able to get away without knowing this by choosing a higher C rated lipo battery but to design the servo controller section I badly need these values.
So what can I do here? Should I do some testes to find the current? I only have a simple multimeter and not even a clamp meter. Please advice
