I know you are new to the electronic field. Also, I guest you burn a few LEDs at this movement (haha). Do you want to know why? Okay then, stick to my article. I will explain how to connect LEDs correctly and also what is the reasons you burn your LEDs. (tags: Simple LED Circuit, 9v battery and led circuit)
First of all, we connect the circuit now, after that you can read what is the theory behind all these things as your interest. All of these theories are explained at the end part of this article. Okay let’s go to the article but I recommend reading the theory part first and after reading these things.
What do we need?
- any colour of the LED
- 10, 390, 470, 560 ohms
- 3v, 6v, 9v, or 12v
- normal circuit wires
We have two terminals in LED, a longer one for the positive terminal and a shorter one for the negative terminal.
Simple led circuit: 1.5v battery
Do you have a 1.5 V battery? okay then, find another 1.5 V battery. Because LED needs a minimum of 1.8 V to operate, therefore, you can’t operate a LED using a single 1.5 V battery. (1.5 < 1.8)
Simple led circuit: 3v battery with 10 ohms resistor
Okay, here is the simple 3 V LED circuit diagram and the Example circuit that I made for you. First, you can find 3 V battery or get two 1.5 V battery and connect them with serial way like the diagram and also use 10 ohms resistor to protect the LED but it was not necessary. always remember that the longest pin in LED is for positive (+) and a shorter one for negative (+). I hope you can understand this and also please read the Theory part of this article which is in the end part of this article for more information.
Simple led circuit: 6v battery with 390 ohms resistor
Here you can see the circuit diagram and also you can use four 1.5 v batteries or one 6 v battery with this circuit. The 390 ohms resistor is the most important component in this circuit and also if you forget to connect this to the circuit then surely your LED will burn. You have to read the final heading (Theory) of this article to get more knowledge. (tags: Simple LED Circuit)
9v battery and LED circuit with 470 ohms resistor
Here are my 9v battery and led circuit with a 470 ohms resistor. Also, You can see positive and (+) and negative (-) terminals are marked in the 9V Battery. Also now you know the positive (+) terminal is the longest pin and negative (-) terminal is the shorter pin in the LED. For more information, continue reading this article and also you can get all the knowledge about these LEDs, Resistors, and Batteries. (tags: Simple LED Circuit, 9v battery and led circuit)
how to connect led lights to car battery (12 v battery with 560 ohms)
Here you can see, this diagram shows how to connect a LED with a Car Battery (12). You have to use 560 ohms resistor to connect with this circuit and also you can refer more with this article. (Read the theory part of this article which is in the last) (tags: Simple LED Circuit, 9v battery and led circuit)
Hi there, Welcome to the boring part of this article and also Please refer to this part completely I’m sure you will get something from here. Don’t forget to comment on this article and also give your idea and point out the topics that I missed here. 🙂
I hope you have a battery and some LEDs. When you connect your LED to the battery directly it will destroy immediately. Do you know normally LEDs are working in the 1.8 – 3.8 V voltage range? However, the range varies with the color of the LED. (tags: Simple LED Circuit)
The following chart will help you to understand the LEDs operating voltage.
|Color of LED||Voltage (V)||Current (mA)|
|White||3.2 – 3.8||20 – 30|
|Warm White||3.2 – 3.8||20 – 30|
|Blue||3.2 – 3.8||20 – 30|
|Red||1.8 – 2.2||20 – 30|
|Green||3.2 – 3.8||20 – 30|
|Yellow||1.8 – 2.2||20 – 30|
|Orange||1.8 – 2.2||20 – 30|
|Pink||3.2 – 3.8||20 – 30|
|UV||3.2 – 3.8||20 – 30|
Okay, now take your battery and check it’s the voltage. Also It has been marked on the battery. It should be one of the following values: 1.5V, 3V, 6V, and 12V. (tags: Simple LED Circuit)
LED with 1.5v battery
Let’s see what happens when you connect the LED directly with the 1.5V battery. Now you know LEDs operating voltage is between 1.8 and 3.8V. but when you supply 1.5V to the LED, which is lower than the minimum operating voltage of the LED. Also If the battery has 1.5V, you cannot get the perfect brightness from it. Then you realize that you can’t emit light from
LED using a 1.5V battery.
LED with 3v battery
Now let us see what happens when you connect the LED directly with a 3V battery. 3V is a value, which is in the operating voltage range of LED. Now again look at the “table 01” that I mentioned above. According to that, you can see white, blue, green, pink, UV needs a minimum of 3.2V to get maximum brightness. Then you can understand that you cannot operate these color LEDs using a 3V battery. However, according to “table 01” red, yellow and orange LEDs have 2.2V of maximum operating voltage. But 3V > 2.2V. Anyhow, we can see led can emit brighter light without burning when they connect into 3V. But it can shorter their life. Also To avoid this problem we can use resistors. (tags: Simple LED Circuit)
LED with 6v, 9v, and 12v battery
Finally, let’s see what happen when we connect LED directly with 6V, 9V or 12V battery. I think now you have all the knowledge to imagine this situation. These voltages are higher than the maximum operating voltage (6V/9V/12V > 3.8V). Also, If we connect LED directly with these batteries immediately it will burn. To avoid this you need to use resistors. (tags: Simple LED Circuit)
Now let’s see what is the resistor. The resistor is a very important component in electronics. The resistor is used to block the current through a circuit and then reduce the voltage of the component that we need. Also, Resistors can connect series or parallel with the circuit according to our requirements. When it comes to the LED, resistors are connected series with LEDs. Also, The value of the resistor can be calculated using the color code. (tags: Simple LED Circuit)
Let’s see about the circuits
You can scroll up and see the relevant circuit diagram that I provided in with the related title.
3V basic LED circuit
Let’s see how we can connect LED with a 3-volt battery. Also If you are using Red, Yellow or Orange color LEDs, you need to connect it through 10 ohms resistor.
6V basic LED circuit
If you are using red, yellow or orange color LEDs, then connect the LED through 210Ω resistor. Also If the LED has a different color (except red, yellow and orange) we use 140Ω resistor series with the LED.
9V basic LED circuit
If you are using red, yellow or orange color LEDs, also you need to use a 360Ω resistor with LED. Or if you use a different color than above use 290Ω resistor to protect your LED.
12V basic LED circuit
If the LED has red, yellow or orange use 510Ω resistor series with the LED and also if LED has different colors use 440Ω resistor. (tags: Simple LED Circuit, 9v battery and led circuit)
