# Arduino project: ultrasonic sensor + 5M 5050 RGB LED strip lights

I'm relatively new to electronics, and as a newbie, I am seeking advice.

I'm my current project, I would like to test out the combination of RGB LED strip 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. I'm not too familiar with how to find or work out the Forward Current $I_f$ (mA) and Forward Voltage $V_f$ (Volts).

I bought my LED strip package from eBay. The components included in the 5MT LED Kit were:

• one 5050 5MT RGB LED Flex Strip Waterproof IR Controller;
• 44 Key Remote controller; and

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 an Arduino project example combining an ultrasonic sensor with an RGB LED strip such as the one I bought?

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

• Was there any progress on this project? I am looking to do the same.
