Re: [PD] Bang order entry
Hi João If the first bang is triggered, wait some time and if within this time frame the second is triggered as well, then you know the direction. It's actually mostly about timing and to make sure to clear the state after a certain time, if not both bangs are triggered within the time frame. Check the attached (ugly; done with touchpad) patch.

Re: [PD] Bang order entry
With Firmata, you should either get a 1/0 with a digital input or a range between 0-1 for an analog value. .hc On Aug 17, 2010, at 9:51 AM, João de Brito Rocha Reis Vidigal wrote: As it is coming from the arduino firmata, the only way I know is that the signal inputs a bang.

Re: [PD] Bang order entry
As it is coming from the arduino firmata, the only way I know is that the signal inputs a bang. So I'll have 2 bangs being hit with a delay between them. this delay depends on the speed of the body crossing the sensors and its size! calling them bang1 and bang2, if the order is bang1 then bang2 = coming in, if it is bang2 then bang1 it means coming out. the thing is I think I have to pair the hits to set an order and I just don't know how to pair them and read it to then bang an in or an out.
