Hi guys, I'm doing robotic arm. i bought some servos: SG90, 2xSG-5010, M160mg.
Before doing construction i've run them without load, they were working. Now i've done all of construction thinks, i've installed and wired up al of them. Suprisly they wont work. Used Sweep example, only what i get was strange moves by servo - like epileptic moves. some of them just wont work.
If i give them voltage and manually moves them, there aren't any resistance
Thank You for Your guidance,
