I have 30 solenoids, i would like to on it one by one with the same frequency or difference frequency. but current producing of the solenoid must be 3A or above. Can some one give some suggestion?

  1. One Microcontroller
  2. 30 output points with solenoid drivers
Piece of cake!

You can use 30 555 astable circuits to determine the frequency of each solenoid and a decade counter to activate each 555 one by one.

can you explain clearly this process? can it be simplified the circuit? because i am using the solenoid to create maglev train
