Hello,

I am tying to use the mosfet and relay as explained in experiment 3C.

Buth i am not getting the required results. The Mosfet does not switch.

What is the problem? When i measure the voltage on the gate i get 2.4V and 2.1V when switching.

Should this not be around 4.2V when high and 0.7V when low?

thx
