So ... I don't even know how to word this because I get a feeling the word 'noob' might be used so I'll just explain
I bought 1.8V LED colored switches. I haven't built anything in a while so I daisy chained 5 together with a 9V supply and none came on, tested and the supply end was 9.15v with 1.85v running across each switch's LED, not my math that's just what it said both of the meters.
I used an Ethos and a cheap generic Maplin multimeter on them separately and I get nothing from diode mode.
I dug out a step down I have and they came on in parallel at 1.8V. Only I haven't used my step down in 10 years and then I remembered I don't own a step down, I own a buck converter and there's no decimal point between 1 and 8. So they ran at 18V for several minutes, about 5.
I then went and connected one to a pot and my multimeter. It came on at 1.7/1.8V, but never really kicked in until about 2.2V. But it turns out my pots are junk it would seem so now I have to either put an Arduino on the case when I get time or wait for all my new gear that's 3 weeks in the post.
Apart from 1.8V for the lamp and the switches ratings there are no other clues. I then asked the seller for the range but all they could tell me was '1.8V'.
I don't know what I bought. I thought it would have been all clear LED's inside, has anyone got any ideas? Maybe I'm missing something, my last post on here was 12 years ago and that's when I stopped. My stuff is all ATMel PIC chips, home made JTAGs and several still sealed Arduinos and an ATMega 1280.
If this is something obvious I forgot, don't laugh too much Though I am sort of hoping it's because I am behind the times at the moment.
Edit: I forgot, my old posts prior to some point were deleted, so yea, 2 posts before I fell off the Earth.
