Moon clock to bright.

Post by keli »

Just finished the Moon clock. My only problem is that it is to bright. I have a diffuser on the way and that might help. I read some where in the forum, that it had not been worked out how to dim the display electronically. I guess I see that you could not PWM the power going into the matrix, that would screw up the ICs on the matrix, I guess. If you could separate out the supply to the Matrix ICs from the LEDs, then you could PWN just the LEDs. Does any one have a solution on how to dim the display electronically? K

@keli,

You could start with a software modification:

Code: Select all

DISPLAY.brightness = 0.1
* 1 would be full brightness
* 0 would be the lowest level

https://github.com/adafruit/Adafruit_Le ... ck/code.py

We do sell rotary encoders with i2c connectors that could be added to the Matirx Portal. That would require merging some example code for that device to adjust the brightness with a manual control.
