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
- a power supply adapter.
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.
