How To Make A Simple Robot With Everyday Supplies 10 Steps

Solder the negative (black) wire of the battery pack to the short terminal of the LED lights. Take a 100 ohm resistor (or a resistor close to that range). Without the resistor, the light will die out. Solder one pin of the resistor to the positive wire of the battery. Solder the other pin of the resistor to the LED’s positive terminal. Connect the two positive pins of the two LED’s. Connect the two negative pins of the two LED’s. {“smallUrl”:“https://www. wikihow. com/images/thumb/b/ba/SolderLED. jpeg/460px-SolderLED. jpeg”,“bigUrl”:"/images/thumb/b/ba/SolderLED. jpeg/728px-SolderLED. jpeg",“smallWidth”:460,“smallHeight”:307,“bigWidth”:728,“bigHeight”:486,“licensing”:"<div class="mw-parser-output">
