How To Make A Simple Led Circuit 10 Steps Instructables First, take one resistor and place stick one end of it in the red line as shown in this photo. go down a couple dots and repeat with the other resistors. take the other end of the first resistor and place it next to pin 1 on the switch block. put resistor 2 next to pin 4. place resistor 3 next to pin 8. Step 1: 3 volt basic led circuit with 10 ohms resistor. the above diagram shows a 3v led circuit, in this circuit there are two aa cells are used. when you are operating an led with 3v you have to use minimum 10 ohms resistor . for more details visit simple basic led circuit.
How To Make A Simple Led Circuit 10 Steps Instructables Step 2: the led. leds come in different sizes, brightnesses, voltages, colors and beam patterns, but the selection at radioshack is pretty small and so i just picked up a couple different leds from what they had in a few different brightnesses and voltages. Connect the positive leg of the led to one end of the resistor using a connecting wire, and connect the other end of the resistor to the positive terminal of the battery. next, connect the negative leg of the led directly to the negative terminal of the battery using another connecting wire. make sure all the connections are secure. This video demonstration shows how to design and build a simple circuit to illuminate an led. the circuit is built on a breadboard, and uses a 9 v battery, r. It is probably the first circuit anyone makes when they interact with electronics for the first time. so, in this project, we will review the basics & will understand the working principle of a basic led circuit corresponding to different supply voltages. this is a very simple electronic circuit requiring only three elements: an led, a voltage.
