Hi, i'm looking for some treads with a quiestion like mine but i can't find anything..
I created a sketch to control a lot of relays acording to a temperature from a ntc thermistor and display it in a 128x32 led display with adafruit, this is working well but now i bought a ds18b20 temperature probe and a 8x32 max7919 one colour led matrix...
I am a beginner as you can see and i have some days tryng to display a float value in my led matrix but i don't know how to do that.
I tried with some examples in the parola MD and max79xx libraries and it is easy to display text, but i don't know how to print a float value.
This is my first time posting a question in this forum, so i hope you can help me.
