Lego WeDo 2.0 Hardware: Unlocking the Power of Remote Control

The Lego WeDo 2.0 Education Kit has revolutionized the way we interact with our creations, introducing Bluetooth Low Energy (BLE) technology that allows for wireless connectivity and remote control. In this article, we will explore the hardware requirements necessary to unlock the full potential of the Lego WeDo 2.0 platform.

To get started, you'll need an Android phone or tablet with BLE compatibility. Essentially, any device with Bluetooth 4.0 or better is compatible. If you're unsure about your device's capabilities, there are many 'BLE checker' apps available on Google Play to verify this. For example, the Google Play BLE checker app can help you determine if your device supports BLE.

The Lego WeDo 2.0 kit comes with a Smart Hub, one motor, one tilt sensor, and one proximity sensor. While this provides a solid foundation for building and programming, it's essential to note that the standard kit only includes a single motor. If you want to add more motors to your project, you'll need to purchase them separately.

In contrast to its predecessor, the Lego WeDo 1.0, which was tethered to a desk via a USB cable, the Lego WeDo 2.0 allows for wireless freedom and remote control. The motor/sensor connections are different from those in the Lego WeDo 1.0, and they are not compatible with each other.

For those interested in exploring the world of Lego WeDo 2.0 app development, there is a range of resources available online. One inspiring example is the Tilt To Drive App for Lego WeDo2, which can be downloaded from Google Play. This app was created by an individual who has also developed the first MIT App Inventor App for the Lego WeDo 2.0 platform.

The development of the Lego WeDo 2.0 BLE control codes involved a combination of BLE sniffing and hands-on reverse engineering. The work of Major Alvega, a Lego-inspired blogger, provides valuable insights into the process.

Faced with the limitations of the official Lego WeDo 2.0 app, which was only available for tablets and lacked an intuitive interface, I decided to create my own app. This project aimed to construct an improved Lego WeDo 2.0 car that could be steered using an Android phone or tablet with BLE capabilities.

By exploring the possibilities of Lego WeDo 2.0 hardware and software, we can unlock new levels of creativity and innovation in robotics and coding education. Whether you're a seasoned developer or just starting out, the Lego WeDo 2.0 platform offers endless opportunities for exploration and experimentation.
