Im currently doing a project related to environmental moods. The basic is that, I gathered several sensors (sound, PIR, DHT11) and the changes in the environment will be detected by these sensors and displayed on a sign (45cm H & 150cm W) that im planing to light using WS2812b strips and controlled using an Arduino Nano. My display is a DIY I did using cardboards shaped into large block letters. I have few questions and suggestions.
I don't want to use the WS2812b strip right away on the sign. I need the individual LEDs on the strips to be placed further away from each other. So i have to cut each LED unit and connect somehow. So, i estimate around 150 such LED units.
Is it possible for me to solder these using thin copper wires? and if it is so, i would like to know the gauge size.
If i solder each unit this way, will there be instabilities in the colours and the illumination of the LEDs?
Can i solder all the 150 units and control using a single Arduino pin? (now, due to the extended distance. 150m long)
I have completed the code and tried using a 60LED/m WS2812b strip. Now i need to expand this to my sign. I highly appreciate any answers and suggestions.
