Hey guys I have some stuff that either I have no clue what it is, I dont know how to use it, or just simply dont want to use it. Ill post some pictures and things as I find stuff.
Here is the first thing, It is a bluetooth module I bought off ebay and didnt know it wasnt broken out. If you want it, PM me an offer. :D
Heres the link to the one I bought: LINK
I have a bunch of these trim pots I got in a surprise box from electronic goldmine, I probably have 150+ of them, I dont have a use for that many if anyone wants some, again, PM me an offer. Sorry about the terrible picture quality.
THe top one is a bluetooth
THe top one is a bluetooth module. So, you can control your robot through bluetooth using android apps (and apps on other platforms that communicate using bluetooth). That looks like an HC-05 module.
The bottom one is definitely a potentiometer. It can be used to vary the resistance and you can do many things like PWMing a motor from 0 - 255, or dimming an LED or changing the contrast on an LCD. Basically, you can turn the shaft and change the analog values. For eg: going from 0V to 5V in small increments as you rotate the shaft.
Yes…
Yes I do know what they are, I bought the bluetooth without knowing it wasnt broken out and I am selling some trim pots because I have way too many of them.
