Is it possible to have multiple analog outputs? I have 5 RGB led's. How can I control all of it? I'm trying to use the HEF4067BP but it seems it cannot send analog values or maybe I couldn't discover how.
Does anyone can give me a direction?
Thank's in advance
The 4067 can send one analogue signal to one of many signal lines on it. There is no way to hold an analogue value on pins that are not addressed.
Where are you getting this analogue output from? No from the arduino as that does not have any analogue outputs.
The best bet is some D/A converters on an SPI or I2C bus.
Maybe I'm not expressed myself well. I'm new to Arduino.
I'm using a Arduino UNO R3 and a HEF4067BP in order to control 5 RGB Led's. The HEF4067 is connected to ports 3,5,6,9 and 8 of Arduino's board.
What I'm trying to do is to output a different RGB value to each one of the 5 led connected to 4067. In my sketch I got 5 different hexa values. I converted this values to 5 different RGB values and I want to light up each led with this values.
No you can not do this with a 4067. It switches one of 16 connectors through to one connector. But only one connection at a time is routed through the chip at any one time.
Grumpy_Mike, thank's for the response.
What kind of chip I will need in this case?
