To make a light-up toy, you'll need a small LED light, a power source like a battery, and a simple circuit to connect them. Start by attaching the LED's positive leg (anode) to the positive side of the battery and the negative leg (cathode) to the negative side. You can enclose the components in a toy casing, ensuring the LED is visible. Finally, secure everything, and your toy will light up when the circuit is completed by connecting the battery.
