I have 4 Shaftless Vibration Motor that needs to be controlled by 1 Arduino. Each motor will be in different pins. And each one must vibrate with different intensities. Sir/Mam/Co-Arduino Enthusiasts, please help me out in the Schematic Diagram in this set-up. I'm having trouble in figuring out the proper values and number of resistors, transistors, capacitor and diode. Thanks!
