In the next stage, enter Wi-Fi credentials like the user name and password for the Wi-Fi router to which your NodeMCU should connect with. Then create a webserver object that listens for HTTP request on port 80ĭefine the ESP8266 pin where Buzzer is connected
ESP8266WiFi library is used to connect NodeMCU to a Wi-Fi network.

All the libraries that we are going to use in this code come pre-installed with ESP8266 board files. So as usual, let's start the code by importing all the required libraries.
Here we are explaining the complete code line by line. The completely soldered board looked like as shown in the image below:Ĭomplete code for IoT-based Smart Keychain can be found at the end of the page. The top layer and the bottom layer of the board are shown below.Īfter making sure that the tracks and footprints were correct, I proceeded with assembling the PCB. The top layer and bottom layer were seamlessly done with proper visa and track spacing. You can check your order status from the ‘Active Orders’ tab.Īfter a few days, we received our PCB from PCBONLINE in a neat package and as you can see below, the PCB quality was good as always. This way, you can be sure that your PCB is fabrication-friendly and will reach you as committed. To make sure the process is smooth PCBONLINE first verifies all the details and Gerber file before proceeding with the payment. In the next step, you have to select the Build time, Shipping country. but usually, the default values work fine. Now in the next window, enter the Gerber file, dimensions of your PCB, the number of layers, and the number of PCB you require.Īfter entering the Gerber file, you can set a few additional parameters if required, like the material used track spacing, etc. Then, go to the Active Orders tab and then click on ‘Quote Online’. Go to sign up if this is your first time. Getting your PCB fabricated from PCBONLINE is easy simply follow the steps given below. Now that our Design is ready, it is time to get them fabricated using the Gerber file. You can also check out our other PCB projects that we have previously built on circuit digest if you are interested. If you want to skip the design processes, you can also download the Gerber file of this smart key finder project using the below link. If you are a beginner who is just getting started in the world of PCB, we would recommend to try getting started with eagle for PCB Designing.

You can design the PCB using any PCB software of your choice. Now that we understand how the schematic works, we can proceed with building the PCB for our project. Fabricating our Smart Ke圜hain using PCB Online The positive terminal of Buzzer is connected to the GPIO2 pin of ESP8266 while the negative terminal of the buzzer is connected to the GND of ESP8266-01. VCC and CH_PD pins of ESP8266-01 are connected to the output pin of AMS1117 while we connect the GND pin to the –ve rail of the battery. This complete setup will be powered by the Lithium polymer Battery and AMS117-3.3V is used to regulate 3.3V for the ESP8266-01 board. The complete circuit diagram for the Esp8266 smart key chain is shown below.

We will explain more on how to use pcbonline later in this article, but for now, lets discuss about the design and working of our IoT based Key chain. The best part is that we can get high-quality industrial standard PCBs even for low volume orders and can also use their free PCB assembly and functional test services when ordering in bulk.

They can handle advanced PCBs with upto 24 layers adhering to ISO standards. PCBONLINE is a PCB manufacturing and assembly service provider who has been in the industry since 1999. Then you click on the toggle button, and in moments, you hear a beep sound coming from your keychain and with this, you can easily track your keys.Īs you can see from the image, we have built this circuit on PCB and we have used PCBONLINE to fabricate the PCB boards for this project. Now in case if you can’t find your keys and you remember that you have attached an IoT keychain to your keys, so you take out your phone and open Chrome and open your Keychain Webpage. So, in this tutorial, we are going to build a simple IoT-based Smart Key Chain just using ESP8266-01, Buzzer, and Battery. Now, the obvious solution here is to place your keys in their right place, but as engineers, what’s the fun in doing that. Many times we misplace our keys and go searching for them everywhere in the house, and after a long search, we end up finding them with much distress. Agree it!!! It has happened to all of us.
