# **node-poweredup** - A Node.js module to interface with LEGO Powered UP components.
### Introduction
LEGO Powered UP is the successor to Power Functions, the system for adding electronics to LEGO models. Powered UP is a collection of ranges - starting with LEGO WeDo 2.0 released in 2016, LEGO Boost released in 2017, and LEGO Powered UP released in 2018. It also includes the 2018 Duplo App-Controlled Train sets.
Powered UP has a few improvements over Power Functions:
1. The use of Bluetooth Low Energy makes it easy to control from a computer, and even write code for.
2. The ability to use sensors to react to events happening in the real world opens up a whole new world of possibilities.
3. As Powered UP hubs and remotes pair with each other, the system allows for a near unlimited number of independently controlled models in the same room. Power Functions was limited to 8 due to the use of infra-red for communication.
### Installation
Node.js v8.0 required.
```javascript
npm install node-poweredup --save
```
node-poweredup uses the Noble BLE library by Sandeep Mistry. On macOS everything should function out of the box. On Linux and Windows there are [certain dependencies which may need installed first](https://github.com/noble/noble#prerequisites).
Note: node-poweredup has been tested on macOS 10.13 and Debian/Raspbian on the Raspberry Pi 3 Model B.
### Compatibility
While most Powered UP components and Hubs are compatible with each other, there are exceptions. For example, there is limited backwards compatibility between newer components and the WeDo 2.0 Smart Hub. However WeDo 2.0 components are fully forwards compatible with newer Hubs.
| Device Name | Product Code | Type | WeDo 2.0 Smart Hub | Boost Move Hub | Powered UP Hub | Availability |
| ------------------------------- | ------------ | ------------- | ------------------ | -------------- | -------------- | ------------ |

### Known Issues and Limitations
* The Boost Color and Distance sensor only works in color mode with the WeDo 2.0 Smart Hub.
* When used with the WeDo 2.0 Smart Hub, the Boost Tacho Motor does not support rotating the motor by angle.
* When used with the Powered UP Hub, the Boost Tacho Motor does not support rotating the motor by angle. It also does not support rotation detection.
* Plugging two Boost Tacho Motors into the Powered UP Hub will crash the Hub (This requires a firmware update from LEGO to fix).
### Usage
```javascript
const PoweredUP = require("node-poweredup");
const poweredUP = new PoweredUP.PoweredUP();
poweredUP.on("discover", async (hub) => { // Wait to discover a Hub
await hub.connect(); // Connect to the Hub
await hub.sleep(3000); // Sleep for 3 seconds before starting
while (true) { // Repeat indefinitely
hub.setMotorSpeed("B", 75); // Start a motor attached to port B to run a 3/4 speed (75) indefinitely
await hub.setMotorSpeed("A", 100, 2000); // Run a motor attached to port A for 2 seconds at maximum speed (100) then stop
await hub.sleep(1000); // Do nothing for 1 second
await hub.setMotorSpeed("A", -50, 1000); // Run a motor attached to port A for 1 second at 1/2 speed in reverse (-50) then stop
await hub.sleep(1000); // Do nothing for 1 second
}
});
poweredUP.scan(); // Start scanning for Hubs
```
More examples are available in the "examples" directory.

<h1><strong>node-poweredup</strong> - A Node.js module to interface with LEGO Powered UP components.</h1><h3>Introduction</h3><p>LEGO Powered UP is the successor to Power Functions, the system for adding electronics to LEGO models. Powered UP is a collection of ranges - starting with LEGO WeDo 2.0 released in 2016, LEGO Boost released in 2017, and LEGO Powered UP released in 2018. It also includes the 2018 Duplo App-Controlled Train sets.</p>
<p>Powered UP has a few improvements over Power Functions:</p>
<ol>
<li><p>The use of Bluetooth Low Energy makes it easy to control from a computer, and even write code for.</p>
</li>
<li><p>The ability to use sensors to react to events happening in the real world opens up a whole new world of possibilities.</p>
</li>
<li><p>As Powered UP hubs and remotes pair with each other, the system allows for a near unlimited number of independently controlled models in the same room. Power Functions was limited to 8 due to the use of infra-red for communication.</p>
</li>
</ol>
<h3>Installation</h3><p>Node.js v8.0 required.</p>
<pre class="prettyprint source lang-javascript"><code>npm install node-poweredup --save</code></pre><p>node-poweredup uses the Noble BLE library by Sandeep Mistry. On macOS everything should function out of the box. On Linux and Windows there are <a href="https://github.com/noble/noble#prerequisites">certain dependencies which may need installed first</a>.</p>
<p>Note: node-poweredup has been tested on macOS 10.13 and Debian/Raspbian on the Raspberry Pi 3 Model B.</p>
<h3>Compatibility</h3><p>While most Powered UP components and Hubs are compatible with each other, there are exceptions. For example, there is limited backwards compatibility between newer components and the WeDo 2.0 Smart Hub. However WeDo 2.0 components are fully forwards compatible with newer Hubs.</p>

<h3>Known Issues and Limitations</h3><ul>
<li><p>The Boost Color and Distance sensor only works in color mode with the WeDo 2.0 Smart Hub.</p>
</li>
<li><p>When used with the WeDo 2.0 Smart Hub, the Boost Tacho Motor does not support rotating the motor by angle.</p>
</li>
<li><p>When used with the Powered UP Hub, the Boost Tacho Motor does not support rotating the motor by angle. It also does not support rotation detection.</p>
</li>
<li><p>Plugging two Boost Tacho Motors into the Powered UP Hub will crash the Hub (This requires a firmware update from LEGO to fix).</p>
</li>
</ul>
<h3>Usage</h3><pre class="prettyprint source lang-javascript"><code>const PoweredUP = require(&quot;node-poweredup&quot;);
const poweredUP = new PoweredUP.PoweredUP();
poweredUP.on(&quot;discover&quot;, async (hub) => { // Wait to discover a Hub
await hub.connect(); // Connect to the Hub
await hub.sleep(3000); // Sleep for 3 seconds before starting
while (true) { // Repeat indefinitely
hub.setMotorSpeed(&quot;B&quot;, 75); // Start a motor attached to port B to run a 3/4 speed (75) indefinitely
await hub.setMotorSpeed(&quot;A&quot;, 100, 2000); // Run a motor attached to port A for 2 seconds at maximum speed (100) then stop
await hub.sleep(1000); // Do nothing for 1 second
await hub.setMotorSpeed(&quot;A&quot;, -50, 1000); // Run a motor attached to port A for 1 second at 1/2 speed in reverse (-50) then stop
await hub.sleep(1000); // Do nothing for 1 second
}
});
poweredUP.scan(); // Start scanning for Hubs</code></pre><p>More examples are available in the &quot;examples&quot; directory.</p>

(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
