I'm a newbie in programming and electronics.

So far, i get better lol, after all i don't get my Vacuum Cleaner to work, it allways going to burn the board, Could someone just please take a look at my diagram and give me feedback.

Thanks a lot!

  • Where does the Arduino get its power from? And it looks like you is drawing too much current from the Arduino. And is there a flyback protection on the fan? To many questions and to little data/info! Please add more.... – MatsK Dec 4 at 10:52
  • Shouldn't the L293D's 5V pins go to the 5V pin of the Arduino, not VIN? – Majenko Dec 4 at 10:53
  • Where's the resistor on the LEDs? – Majenko Dec 4 at 10:54

    How does battery power get to VIN / barrel jack? – Majenko Dec 4 at 10:54
  • @MatsK The Arduino gets his power from the motor driver (5V to vin), (that get the power from the mosfet from a 12 V / 2.2A lead battery,.). So far no flyback diode installed. – JMK Dec 4 at 12:05
