DIY Ir Remote Controlled Led Strip

Hello hi everyone welcome to our new instructables as you already know from the thumbnail that in this project we're going to make an Ir led strip controller which can be controlled using any commonly available IR remote which are generally used in TV. Etc...

hope you will like my instructables....

Step 1: How Our Project Works....

First of all we start by projects part list and how they work like any common machine our controller has three parts input processing and output
.......

Step 2: INPUT..

For the input we need an IR receiver in my case it's TSOP 1838 or simply V 1838 you can use anyone commonly available like the TSOP 4838, 1738, etc. the function of an IR receiver is to change the IR signal from remote to hexadecimal codes in order to use them in our program, etc.. it also help us to differentiate between different buttons of our remote it has generally 3 pins VCC ground and signal you need to know this pin configuration of your receiver before starting the project..

Step 3: PROCESSING....

Now comes the processor, if you are watching me for a long time you all know as always I am going to use arduino Nano you can use any other processor or microcontroller this is the main processing part of our circuit that uses the signal provided by IR receiver interprets it and controls the LED strip as Required..

The Processing Unit is also the control centre of the whole project
I am using a cheap clone of arduino Nano if possible you should use the original one

Step 4: OUTPUT...

Output now comes the last component that we need as we want to control the LED strip which consumes are higher amount of current about 0.5 amp which my controller cannot handle we could use a Relay but using a relay will not allow us to switch between different brightness as a pwm does, so instead we are going to use an N channel MOSFET more specifically an IRFZ44N..



It has got three pins Gate drain and source and provides variable resistance to work similarly as an pwm to control the brightness or Dimmness of the LED strip as required….

Step 5: Bill of Materials (BOM).

Now overall you know how our project works
So let's start by the components that we need and connecting all the parts together…

That project in through the following components :
microcontroller arduino nano
100uf capacitor capacitor
IR receiver and
An N channel mosfet
And a couple of 10k rasiators
And as sure a power supply and led strip...

Step 6: Getting the Hexadecimal Codes.... of Remote

First of all you need to connect digital pin 11 of your arduino to signal of IR and the ground to ground respectively while vcc of the IR receiver to the 5 volts of the arduino respectively now by uploading A Simple code IRrecvdemo from the great IR library and opening the serial monitor and pressing any button on an IR remote we are clearly able to see the hexadecimal code of the Ir Remote button…


But whats it !!!!! a single press results to several no. Of similar codes. To prevent this you need to add a 100uf capacitor between vcc and gnd pin of the ir receiver….

Now after pressing any button it works as required next we need to get the hexadecimal codes of the buttons that we are going to use copy those codes and save it in nodepad or somewhere else…

Step 7: Soldering the Components.....

Now after you gathered all the components and you know how to get IR Receiver codes you need to solder everything on a perfboard or pcb
If you are still confused you are free to ask questions in the discussions below…

It took me about 20 minutes to solder everything on the perfboard…

Step 8: Editing the Codes...

Now you need to add hexadecimal codes that you have copied earlier to the main program wherever needed and upload to arduino without any further changes if you want to modify your project or you want to use more than one led strip you are free to modify the changes in the programs…

Step 9: Ending the Project...

Now our project is to end, now you need to power the circuit with 12 volts as i am using a arduino clone i had to use a different power supply of 5v for it but if you are using the original one you should use only a 12v power supply. now after it is completed i tested it and it worked as it was supposed to....
thanks for giving your wonderful time to read my instructables….

Step 10: SUCCESS...

Now its complete enjoy playing with it..

Actually it looks pretty good as well as compact hence it can be placed anywhere unnoticed....

Hope you will share your experiences if you made it......
