Connect the low value resistor and the LED to the battery in series and the LED will turn iluminate. I’m using a breadboard for this, which makes it very quick and easy to test electrical circuits, but you can also just twist the wires together, you can solder them or use some connectors and it’ll all work fine for this simple experiment.
Another way to light up an LED is to just connect it to a coin cell battery! Since the coin cell can't source enough current to damage the LED, you can connect them directly together! Just push a CR2032 coin cell between the leads of the LED. The long leg of the LED should be touching the side of the battery marked with a "+".
• The LDR must be connected to the positive terminal of the battery (red wire). • The longer leg of the LED must be connected next in the circuit on the positive terminal side of the battery pack. Your LED may light up if you are working in a light room but, if not, try shining a torch on to the LDR.
• The longer leg of the LED must be connected next in the circuit on the positive terminal side of the battery pack. Your LED may light up if you are working in a light room but, if not, try shining a torch on to the LDR. Ask your challenge leader if you do not have one.
The positive and negative wires should then be taken from the LED lighting and attached to the matching terminals on the SEC (secondary) side of the driver. Often, LED drivers and transformers do not include terminals, and so users must directly wire a plug to the end of the cable.
To control, you could use a constant current LED driver. There are even LEDs that emit light outside of the normal visible spectrum. You probably use infrared LEDs every day, for instance. They're used in things like TV remotes to send small pieces of information in the form of invisible light!
I wrapped my positive wire from the battery to the positive electrode of the LED and wrapped the negative wire from the battery to my negative electrode and presto - let there be LED light! …
