Relatively new to electronics, as a newbie I am seeking for advises, thank you in advance.

Current project, I would like to test out the combination of RGB LED strip lights controlled by one ultrasonic sensor. I am starting to gather my materials and components, however I am having some trouble to determine which type of resistors I should use for the circuit? Not too familiar with how to find or work out the Forward Current If(mA) and Forward Voltage(Vf).

Brought my LED strip package from ebay; Package Include For 5MT LED Kit: 1x 5050 5MT RGB LED Flex Strip Waterproof IR Controller, 44 Key Remote controller and Power Supply adapter.  (website:

5050 5M RGB SMD LED Strip Light , according to the information from the seller it should be 150pcs of led/5M.

Power Supply Specification:

Input Voltage: 100-240V 1.5A

Output Voltage: 12V DC

Output Current: 0 - 5A

Output Power: 60W

Safety Compliance: CCC/ FCC / CE / UL / GS

Working Temperature: 0°C-40°

Storage Temperature: -20°C-60°C

My next inquiry is has anyone been able to find a arduino project example, for the combination of ultrasonic sensor with RGB LED lights?

I've found some youtube videos however aside from the video there are no excess information I could use as reference...

Many Thank you for the patience you have given!
