Only 2 of the corners should come into contact and you can use a small drop of superglue to affix these to keep the cover slip firmly in place.
Arduino laser power meter.
At this step you don t need to connect oled display to the arduino just connect tx line of the laser rangefinder module to the tx line of the arduino and power lines of the module to the 3v power source.
During my childhood days continuing studies after dusk was a real challenge.
The goal of this project is to give hobbyists access to a diy lpm design for only the cost of hardware that they can expand and modify to suit their needs.
When your laser target has completely dried for a minimum of 24 hours put the glass slip into a 33mm slide holder or a cardboard holder fashioned in a similar manner.
