Hi ! I start to electronics with arduino and i try to make a project: a car (IR) wich turn with a servomotor and move with a dc motor, so I have to use mosfet with an external electric source: 6 batteries in series(9V entire) to move the car that’s my code and my mounting.
The problem is that when I apply “HIGH” to mosfet ’ gate, it closed drain/source but the voltage transfer is very low compare to 9V waiting, I mean the motor don’t receive 9V but ~1V
It has been for 4 days i search why and i don’t understand very well how function precisely a mosfet/transistor so if anyone can answer my question and help me to solve the problem I will be happy.
