am trying to set a digital port d23 on or off
set(D23,on) seems something missing here.
i check cheet but it confuse me.

you solved the problem,i didn now if the true or false must be written.
now i know i dont.and yes set(D23,on)
its for the police light,cause it change mode with his own board ,i cant get it out.
Let me explain in more detail...
- The regulator power is connected to the VCC +7.4 volt pin on the EZ-B
- The regulator GND is connected to the EZ-B Signal pin
* When the signal pin is HIGH, it will output 3.3 volts and the light turns off.
* When the signal pin is LOW, the output is GND and the light turns on.
Now, here's the problems
1) You're powering the regulator from the ez-b signal pin when it's GND, which micro general purpose i/o pins are not designed to provide that much power.
2) When the signal pin is HIGH (on), it connects it to the VCC (7.4v)! Even though it's running through the regulator, there's not that much resistance - and therefore you're feeding way too much current back into the EZ-B v4 I/O
What you want to do is control the light by using a TP-220 or any transistor. There are tutorials that explain how to do this.
Stop what you're doing now or you will damage the EZ-B.
thanks for posting.this is a wake up call,dont experiment.
@Nomad, do you have a datasheet for those lights or did they come with directions?
they have there own board.
Can you tell us the model number of that strobe light?
11_24..8335
v-11-12-h
thank you i have a try .
dont work,the light is allreddy burning when plug into d23
i try servo(d23,90) and 180 and also setservomin and max.
Can you upload a picture of the light including the wiring?
