This would work... Maps the adc's input between 0 and 255 to servo degrees 1 to 180. It'll work on d0 and ADC0.


while (true) {

  // duplicate this line for other servos
  Servo.setPosition(d0, Utility.map(ADC.get(ADC0), 0, 255, 1, 180));

  sleep(100);
}

hi dj

i wanna use two ez wheel servo's. looks like the script is for one servo?

this what i have .

while(0)(true)
while(1)(true)

{ // duplicate this line for other servos

Servo.setPosition(d0, Utility.map(ADC.get(ADC0), 0, 255, 1, 180));

Servo.setPosition(d1, Utility.map(ADC.get(ADC1), 0, 255, 1, 180));

sleep(100);

}

lol how did you get that from my example hehe. Here you go...

while(true) {

Servo.setPosition(d0, Utility.map(ADC.get(ADC0), 0, 255, 1, 180));


Servo.setPosition(d1, Utility.map(ADC.get(ADC1), 0, 255, 1, 180));


sleep(100);

}

haha i was not far off.but it doesn move the ADC0 servo. it move head d0 and d1. i wanted to use ADC0 and ADC1 alone

hi ezang

waiting for parts.do you have any idea how adc ports work with continious rotation?

oh does the adc only have 3 volts?

did you read the link I put on?

Steve said: Step 1. About the ADC ports. There are 8 ADC Ports on the EZ-B v4 numbered "A0" to "A7" that you can connect devices like analog sensors. Each ADC port contains three pins...

Ground: (output) located towards the centre of the board.

VDC: (output) The centre pin, regulated at 3.3 volts.

Signal: (input) The outermost pin from the centre of the board which reads the voltage between 0 and 3.3 volts.

The ADC ports are Configurable at 8-bit (0-255) or 12-bit (0-4095) in software.

In an ADC control found in the ARC software, such as "Read ADC", ADC reading intervals can be selected from 100 ms to 60000 millisecond analog values.

Analog readings are from 1 to 255 (0v to 3.3v) in 8 bit mode, or 0 to 4,095 in 12 bit mode.

I have to leave now  - maybe Ptp or DJ can help, sorry

i saw it but you cant controle a servo on a adc port itself. i wonder would a LED work? on a adc port?

Sorry for all the links, I personally never used ADC yet,  Read this link:

Seems like you need a script:

Rich:

ADC to servo movement

:loop $value=GetADC(ADC0) $position = $value/100 $position = Round($position,0) Servo(D1,$position) Sleep(250) Goto(loop)

Or

/ ADC to servo movement

:loop $value=GetADC(ADC0) $position = $value/100 $position = Round($position,0) $position = Map($value, 54, 129, 180, 1 ) #adjusted first two values to read min/max read ADC project, 2nd two for direction (reverse 1 and 180). Servo(D0,$position) Sleep(250) Goto(loop)

from NallyCat - @Nomad 6R there is a tutorial on synthiam for that, have a look at " Using ADC (Analog to Digital) Ports, Commands and Controls." by Steve G.

Looks like the one I already gave you - check

i have another question about adc ports.didn want to open another topic. is it possible to control a LED ,excample on/off ,with an adc port? i notest a led goes on from 3 volt.
