		low mosfet			rem ensure the system starts with the mosfet off

begin:		readadc10 brightness,w6		rem read the brightness setting pot
		if w6 < 10 then stopped		rem if value less than 10 turn lamp off
		pwmout mosfet,255,w6		rem turn on the lamp at a brightness as read from the pot
						rem PICAXE duty cycle (w6) is a 10 bit value which needs 2 bytes
						rem of 8 bits each hence w6 which is a 2 byte register
		goto begin

stopped:	pwmout mosfet,0,0
		pause 50
		goto begin
