- | * [[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]]. | ||
