Topic: Multiple Cold Cathodes with Diming (Read 970 times) previous topic - next topic



This is my first time to use a cold cathodes lightings.
The cold cathodes I have is 2 lightings + 1 inverter = 1 set
and, I want to control the dimming and powering 4 sets (total 8 cold cathodes and 4 inverters) all together.
Since 1 set supposed to connect 1 AC/DV 12V adapter, I wonder if I can connect 4sets with one power adapter.
Also, one arduino and dimming circuit between dc adapter and a connector from all inverters.
The company suggests use 5amps adapter for 4 sets connection. (2amps for 1 set)

I have not tried dimming cold cathodes, only incandescent with PWM dimmer.
I am going to connect a 'ultrasonic distant sensor' to brightens and dims the lights.

without the sensor :

Will I not require external dimmer, but with the breadboard circuit? what schematic should I look into? with the sensor?
Will this work?

thank you.
