Hi Guys! New to arduino but i do a lot of pixel and LED

Hi Guys!

New to arduino but i do a lot of pixel and LED work. FastLed seems awesome. I have bought a bucket load of sensors and arduino bits (floras, gemmas, teensy, fadecandy, uno v3, pi).

Ive built a couple of small projects using the flora but i am just copying and pasting code. Ive edited a couple of pieces of code which have worked but it still feels like cheating.

Ive just been testing out analogue sensors (force strength resistors, potentiometers and a lux sensor). I have mapped them to a small strip of ws2813 i had lying about.

My next question is how/where can i learn how to use fastled comprehensively. I want to be able to use sensors to create effects but im struggling to find much info which means i’m probably looking in the wrong place.

@Gimbo_Goombar - Look at the amazing work by @Sam_Guyer and his great instructables project using sensors at:

Also, use the Search Community box on the left side of this webpage and try the search term: sensor.

Also, check out the ESP32.

Brilliant thanks guys. Ive had the fsr illuminating a vatied number of LEDs (i found a guide with the potentiometer and used the fsr instead with a pull down resistor?)

Will carry on with this when i get home. I ideally want to be able to map an analogue range to illuminate an amount of pixels a specific colour.

Something like 0-300 would illuminate the first 30 pixels green 301 - 600 would illuminate the next 30 pixels orange and then 601 - 1023 would illuminate the remaining pixels red!

Sounds nice! I made a really simple gadget that shows ambient volume by reading an analog value from a microphone and displaying it as a range of pixels on a strip – like a stereo equalizer. I’m happy to share that code if you like.

Yeah that would be awesome Sam! So far im finding it more interesting reading code than doing the projects haha!

I cleaned up the code a little and added comments. You can see it here:
