Can somebody explain to me why this circuit will not work? It might be that IRF3205 isn't a great choice for an Arduino but it works for Adam Welch on youtube so it should be possible. Tried it even with a 10k resistor gate to source.

When I measure it when the gate goes LOW:

  • Gate is 0v

  • Drain is 3.7v

  • Source is 3.7v

When I measure it when the gate goes HIGH:

  • Gate is 5v

  • Drain is 8.7v

  • Source is 5v

EDIT: Missing in the diagram is the ground to ground connections
