App Inventor (AI2) is an easy way to create Android apps. While originally designed for teaching, it still allows building advanced and complex apps, and was the tool I chose to build a software 2-axis joystick interface for wireless vehicle control. This article describes the implementation of the joystick as a standalone component that can […]

In a previous post, I looked at creating reliable communications using Classic Bluetooth. While that approach works well, and is a reliable way to connect devices, there may be circumstances when a Bluetooth Low Energy (BLE) connection is preferable. As it turns out, Bluetooth and BLE are about as similar as apples and oranges. The […]
I recently needed to develop a Bluetooth application between an Arduino and a controlling App running on Android. App Inventor 2 was used to simplify development of the Android App . MIT App Inventor (AI2) is a web-based online graphical mobile application development environment for Android devices, where you can create an application by simply dragging and […]
In the previous part I described the changes to the original SmartCar project related to hardware and sensors. In this post I’ll continue with the changes made to the software and control software, and the resulting improvement in the behaviors of the rover example application.
In keeping with the original aim of replicating the Rug Warrior, described in the first part of this series, in this final part we’ll use the MD_SmartCar library functions to implement a simple random roving robot with similar functionality to the vintage Rug Warrior bot. The objectives for this robot are therefore fairly modest – […]
There comes a point at which the hardware and controls need to be started ‘in anger’ and tuned for performance. There is a lot to set up, but the process for MD_SmartCar is made easier by following logical steps, building up from simple to more complex activities. This article outlines these steps from beginning to […]
In Part 1 I described the hardware components and the functionality of the LED clock. This this part, I’ll explore the software required to implement the functionality and seamlessly manage the different user interfaces.
