I have a very simple circuit that isn't quite doing what it should.
I am using a radio control receiver module to drive a mosfet - a BUZ72 which drives a LED (for testing purposes)
So the output from the receiver module goes to the gate
The source goes to ground
The drain goes to an LED (the other side of which goes to VDD)
And there is a 10k resistor between the gate and ground
I'm running this off 4 x AA batteries
The output from the receiver toggles (i.e. when I press the button on the transmitter it goes on; when I press it again it goes off.) All this works fine.
But the LED doesn't quite follow this. It goes on, but when I press the button again, it doesn't always go off: often it flashes off and comes on again.
This also happens when I replace the LED with an actuator.
Any ideas please?
