in my project I use an accelerometer conected with the arduino uno and some SMD LEDs. I would like that the brightness of the SMD LEDs goes along with the data of the accelerometer.
I already programed it and used the PWM of the Arduino (brightness from 1 - 255 to dim it with switching the power on and off that it seems for the human like its dimed).
My problem is now that it's not dimed enough for my use. I would like to have a smooth transition from dark to bright, but at the moment it starts already to bright. Even if I just take a single SMD LED and higher slowly the voltage it first doesn't shine and when it starts its already kind of bright.
I read on the internet that its not possible with every led to dim it at e.g. 1% of the brightness.
Do you know a possibility how to dim a SMD LED to e.g. 1% of the brightness or do you know any SMD LEDs with which it's possible?
Thank you for helping!
