Hi guys,

can anyone help me out with the wiring on rotary encoders,
I have bought a pack of the ones without the pcb attached,
So I have three pins on one side and 2 on the other,

If someone can relate those pins to the labels clk, dt,sw,+,gnd then I
think I can follow the instructions on the forum to make the various
projects.

thanks

Les

Ask Mr. Google.



CLK = Encoder Pin1
DT = Encoder Pin 2
SW= Push Button
5V = 5 V ( Same Arduino where you set the 3 Data Pins)
GND= Ground ( Same Arduino where you set the 3 Data Pins)

( I Not Use this kind of Encoders.... Maby the High/Low Logic is inverted.... then you have to change the Encoder Pins.... Then DT= Encoder1 and CLK is Encoder 2 Try Out )

Hi,

thanks for the reply, I think ill have to get some of the encoders with the circuit board attached, as in your picture,
Looking at google , I need to wire in extra resistors to the ones I have, which seems difficult..

thanks

Oh.

i thought you got the KY040 Encoders ! Only this kind need a wireing with PCB and resistors !

If you got a standard Encoder like maby this https://www.reichelt.de/Drehimpulsgeber/STEC12E08/3/index.html?ACTION=3&LA=2&ARTICLE=73923&GROUPID=3714&artnr=STEC12E08&SEARCH=%252A
THEn you not need a resistor.... The Side with 3 Pins is for the Encoder ( Encoder Line 1 , Encoder Line 2 and GRD ) the Side with 2 Pins is for the Push Button (Putton Pin , GRD )

Here simply combine the two GRD and set the 3 Data Pins to 3 Slots on the Arduino ! ( 2 for Encoder, 1 for Button)

Best way : Pleas check WHAT Encoder you got and google for the DataSheet.... "Normaly" all KY040 Encoders are pre Mounted or include the Pcb´s. If you only got the Encoders without PCB i´m pretty shure you got "normal" ones !
