<h1 id="Quick-Start"><a href="#Quick-Start" class="headerlink" title="Quick Start"></a>Quick Start</h1><p>This project aims to help web developers who are not familiar with firmware programming to implement their own IoT applications. You only need a server inside the network (such as Raspberry Pi) and several MCUs (single-chip computers) that support networking (via serial port, WiFi, LoRa, Bluetooth, Zigbee, etc.), you can easily create and manage your own Internet of Things Cluster.</p>

<p>For <strong>windows</strong> user, you can follow the instruction in <a href="https://www.jianshu.com/p/03a76b2e7e00" target="_blank" rel="noopener">this website</a> </p>
<h2 id="Install-wIoT-package"><a href="#Install-wIoT-package" class="headerlink" title="Install wIoT package"></a>Install wIoT package</h2><p>After install Node.js and configure npm successfully, you should then use npm to download wIoT package by enter following command in your command window.</p>

<p>Windows user can use cmd or powershell.It should be notice that this may report error for some users. The solution is to open your cmd window as administrator. You can right click on cmd and choose <em>run as an administrator</em>. You can also press windows+R and input <em>cmd</em> then press Ctrl+Shift+Enter to open it as administrator. </p>

<li>After burning the firmware, you should try to connect your device to D1 MINI<br>Follow the steps below, I’m sure it would not be a problem for such a smart person like you </li>
</ul>
<h3 id="1-Reset-your-D1-MINI"><a href="#1-Reset-your-D1-MINI" class="headerlink" title="1. Reset your D1 MINI"></a>1. Reset your D1 MINI</h3><ul>
<li>Find pin <strong>D0</strong> on your D1 MINI, it should be in the middle of A0 and D5. </li>
<li>Use a wire to connect <strong>3V3</strong> to <strong>D0</strong>. If your MINI works normally, you would see its BUILT-IN LED blink. </li>
<li>You <strong>don’t</strong> have to wait until it stops blink, just stay for <strong>2s</strong>, then you can pull out the wire and your MINI would reset. </li>

<li>After you finish step 1, your MINI would work in AP mode, which means you can search it with your smart phone or personal computer by scanning the Wi-Fi around </li>
<li>If your MINI was reset successfully, you would find a Wi-Fi with SSID in the form of <strong>wiot-xx:xx:xx:xx:xx:xx</strong>.<br>Example:<br><img src="https://api.yimian.xyz/img/?path=docs/wiot/ssid.png" alt="ssid"><br>“xx:xx:xx:xx:xx:xx” is the MAC address of this MINI, please try to remember the address for you may use it later </li>

Rebooting!!</strong><br>Then, after a minute, you will see the SSID of D1 MINI has vanished </p>
<p>If you submitted the wrong message, do not try to directly reconnect to D1 MINI. Restart the whole procedure from the reset part of the last section</p>
<h2 id="Execute-Example-Code"><a href="#Execute-Example-Code" class="headerlink" title="Execute Example Code"></a>Execute Example Code</h2><p>If you have successfully connect D1 MINI to your Wi-Fi, you can execute the example code below to realize a simple function of wIoT<br>Before executing the code, you should first connect a LED to D1 MINI with positive pole connect to pin D4 and negative pole connect to GND</p>
