Just for fun and coding experience, I have conceptualized an Arduino project where a laser line sweeps across a surface (wall) and the range to that surface is determined by triangulation. The problem I have run into is detecting the light returning to the source. My initial tests using a 5mw red la...

I took photos as I went along, but I don't see any way to upload them on this forum. For the benefit of others who may attempt thi...

Very nice! Again, thanks for all the work you put into that. Naturally, now I have a few more questions: 1) Cross-referencing your diagram, build tutorial and the included instructions, it looks like pin 15 on the J1 arduino connector has a connection to GND, correct? (not indicated on the schematic...

Thanks for the info. I found a small razor saw guided by a ruler made a decent slot in the board and made a clear separation between the pads about the same width as the originals. I noticed on the all-in-one schematic, it lists a 74AC11138 decoder, but in my kit (and the tutorial), it's a 74HC138. ...

Without them, I'd REALLY be in the dark about some of the aspects of the assembly. Got a question about ...
