I am a novice and tinker. I made a ball lifter for a pachinko machine that feeds 6mm balls to a feed tray.
The circuit is a simple 12 Dc 5a powersupply , feeding a buck converter that outputs 5vdc that powers the sensor and relay board. The sensor triggers the 5v that trips the relay powering the full 12v to a small dc motor. That motor can draw max of 1.8A.
I figured power supply is 5A sobi used a 5a fast blow fuse.
It's working but is this correct?
Should it be closer to 1.8 A of what the motor draws?
I am using a small 20mm glass fuse holder. The fuse is inline from the + side from the power supply feeding everything. I want to protect it just incase the motor jams up it does not burn up the wires.
Video here of it working
