Guest mferolla Posted February 24, 2003 Report Share Posted February 24, 2003 i found a good Infra Red sensor to add to the MidiBox64 in the place of a pot or fader, this sensor is greate because you can do the same of a fader but in the air, like moving the hand, the page of thssi sensor is this onehttp://www.acroname.com/robotics/parts/R48-IR12.htmlBut the problem I have is that the output of this IR is from 0 to 3 V, and what I need If Im not wrong is beetwen 0 and 5!If someone knows how to solve this , would be greate!!Thank you very to everybodyMariano Ferolla Quote Link to comment Share on other sites More sharing options...
Ian_Hurlock Posted February 24, 2003 Report Share Posted February 24, 2003 So why not port the whole lot out thru infra red.Send the midi data to IR receiver at the pc.Ian Quote Link to comment Share on other sites More sharing options...
gillesdeshays Posted February 24, 2003 Report Share Posted February 24, 2003 But the problem I have is that the output of this IR is from 0 to 3 VBut normally the output voltage is : -0.3 to VCC+0.3You power your IR with 5 v ?Gilles Quote Link to comment Share on other sites More sharing options...
Guest mferolla Posted February 24, 2003 Report Share Posted February 24, 2003 YES I power it with 5V but the output as you said is like that what can I do to have the output from 0 to 5 V! becouse that te way that this will work in my midimox64.. :-[Thakxs Quote Link to comment Share on other sites More sharing options...
jerash Posted February 25, 2003 Report Share Posted February 25, 2003 for sure you need to add some electronics to transform these -0.3/+0.3V into 0/5V :-/but maybe not necessary to reach the 5v, and you can adjust the "pot" range in the software (i think we speak about scaling here). Not tested as my midibox is not finished, but i think it's the way it works. :PRAF Quote Link to comment Share on other sites More sharing options...
gillesdeshays Posted February 25, 2003 Report Share Posted February 25, 2003 If Vcc=5 V and Vout=Vcc+0.3 so the output voltage range is 0.3V to 5.3 V ...Do you measure 0 to 3 V at the output ?Gilles Quote Link to comment Share on other sites More sharing options...
Guest mferolla Posted February 25, 2003 Report Share Posted February 25, 2003 I didn't measure ir yet becous eI didn't by the IR, Im traying to fiend out everything beforeI buy it! but if it is how you say It should be Ok, no?Thanks for your helpMariano Quote Link to comment Share on other sites More sharing options...
gillesdeshays Posted February 27, 2003 Report Share Posted February 27, 2003 As far are my mathematics lesson at school ...IF Vcc=5v and voltage output range Vo=-0.3V at 10 cmand voltage output range Vo=Vcc+0.3V at 80 cmThe IR detector feed with 5V will out -0.3V (closest detection) to 5.3V (far detection)So it must work ... protection the chip pinput with a 5V zener diode may be ...Gilles Quote Link to comment Share on other sites More sharing options...
Guest mferolla Posted February 27, 2003 Report Share Posted February 27, 2003 Thank you very ! ass son as i try that i will tell oyu what had happened!!Thanks!!mariano Quote Link to comment Share on other sites More sharing options...
