RGB and Ultrasonic sensor

Using Arduino General Electronics
1

Is it possible to connect RGB to the arduino's analog pins? A0,A1... ? If so how do I light it up in the program.

Same question but with Ultrasonic sensor.

Thanks !

The Analog pins can be used exactly like the digital pins.
Use resistors 100 Ohm+ if you connect a (RGB)LED

Thanks.

Can I connect LCD to any digital legs only or do I have to connect those 3 legs to PWMs.

Which LCD has three legs?

For dimming LED's you need PWM pins. If you don't need dimming you can use any digital pins.

It has 16 legs, 6 of them go to the arduino and 3 out of those 6 due to a sketch I saw on the internet go to PWM pins. My question is whether it's a must to connect them to PWM pins or can I connect them to regular digital pins?

I put on my fortune teller hat and peer into my crystal ball. I see a vague picture of an LCD display with an RGB backlight. Am I right?

LCD backlight LEDs are usually white.

OP needs to start answering questions or this thread is completely futile.
