The assignment of this week is to add an output device to a microcontroller board and program it to do something.
I want to control a stepper motor.
After the soldering of the components, my board looks like the foto
When I programmed the board, it seemed to be ok, but when I connected the motor it didn´t move. I checked all the conections and finally I connected several leds witth its resistors and they where always ligthining .
I measured the voltage at the drain of the mosfet and it was always 5V. I checked the output at the gate and it oscillated between 0-5V, so, the output of the microcontroller was ok.
Finally I noticed that the mosfet I soldered was a P-MOSFET. I replaced the T1 P-MOSFET by a N-MOSFET one and I saw that the LED I connected turned on and off
I have to change all the P-MOSFET and I hope my motor works
