Rotate a 4 wire bipolar stepper motor (32.6 ohm) & activate a solenoid (13.3 Ohm) at different times. Using H-bridge ( LN298 4A) for the stepper & N-Mostfet (tp120) for solenoid. INPUT
I have burnt multiple 1A H-bridges when using the same power source for all (19V 4.74A).
So, I use a 19V 4.74A for the motor & a 12V 2A for the solenoid. (This sucks)
Arduino is running of USB (Already burnt out an arduino when then other H-bridge blew, so i scared)Parts
POWER! How do i safely power this, or MORE, with one power supply? I keep burning things out when I try to use one power supply...
I thought the 19V 4.74A voltage supply would work, but it burnt out my arduino and three 1 amp H bridges.. womp womp...
PLEASE HELP ME OPTIMIZE MY LAYOUT. ESPECIALLY BECAUSE I WILL BE ADDING 2 MORE to THE SAME CIRCUIT. (3 motors 3 solenoids 1 ardiuno) (+LEDs & bla bla). POWER PROTECTION; HOW??
