-AIN module is used to connect potentiometers to the Midibox. It's also possible to use other 0-5V analog voltage sources. (For examples see: [[http://​www.ucapps.de/​midibox_ext.html|Midibox Extensions]] page)+====== ​AIN Module ======
  
-* [[http://​www.ucapps.de/​mbhp_ain.html|AIN Module]] <​sup>​uCApps</​sup>​+**AIN** means "​Analog Input"​. Analog is meant as a range; in terms of voltage this range is normally from 0 to 5 V, in terms of programming this is normally a 10bit value from 0 to 1023.  
 +It's quite clear if you see this in contrast to the Digital Inputs (via [[DIN Module]]), which know just two states: on or off, 1 or 0. 
 + 
 +The AIN module is normally used to connect potentiometers to the Midibox, usually these two types: 
 +  * circular pots => Turning knobs 
 +  * linear pots => Faders 
 + 
 +:!: 
 +**Potentiometers (also "​Pots"​) should have a typical resistance value of 10 kΩ.** 
 + 
 +[[Motorfader]] have to be connected to a special module called [[mf_ng_module]]. 
 + 
 +It's also possible to use other 0-5V analog voltage sources. The [[ACSensorizer]] is a user project especially developed for AIN sources (like sensors) that do not deliver 0-5V exactly. 
 + 
 +The AIN module uses CMOS 4051 multiplexer ICs, each of which provides 8 analog inputs. ​ The most common AIN configuration is sometimes referred to as AINX4, because it has 4 such ICs, for a total of 32 inputs. ​ Two AINX4 boards can be cascaded for a total of 64 inputs. ​ Alternatively,​ an AIN module could be populated with as few as one 4051, if 8 or fewer inputs are required. ​ In MIDIbox-jargon,​ this could be called AINX1. 
 + 
 +The AIN module(s) connect to J5 on the [[core module]].
