working with hardware like arduino is completely new for me.

i bought a arduino kit with "generic components"... and with it is have a stepper motor called "28byj-48" (https://images.app.goo.gl/y7tDxtL9sewgb4HS7)... i want to work on something that can open and close a small window. (to control humidity in a greenhouse)

... so i figure i should add some king of cog or gear on top of the spinning part of the "28byj-48" and have that move something to push the window open.

... but this is where i am stuck.... i have no idea on what to search for. i have tried the following (...and more): "stepper motor gear", "arduino component gear", "28byj-48 attachment".

i don't really know much about mechanical engineering for creating some kind of arm mechanism... and it is difficult to learn because i don't know the search terms for what i am looking for.

i hope i have have been more clear above by specifying the motor name and the "greenhouse window opening" intention.

please ask if more information is needed and any guidance here would be great.

thanks in advanced.

  • $\begingroup$ great! thanks... can you help me to find out what piece i could use to convert the motion of the robot pinion gear into a push/pull motion against the window frame. i will look further into 28byj-48 datasheet. $\endgroup$ – X0r0N Jan 22 at 21:39

    $\begingroup$ google rack and pinion and leadscrew ... also consider how an inkjet printhead is moved $\endgroup$ – jsotola Jan 22 at 21:55

A 5mm Shaft Pinion Gear is where I'm going with a project I'm working on. It may work for you. https://www.amazon.com/s?k=5mm+shaft+pinion+gear&crid=2V71LVY7T7QSQ&sprefix=5mm+shaft%2Caps%2C180&ref=nb_sb_ss_ts-o-p_7_9
