Getting a WS2812 based led strip to work using the FastLED library.
This tutorial describes how to build an electronic circuit with an RGB LED (a LED that can change color), and change its color using an App. It also demonstrates two-way communication over Bluetooth LE between an App built with App Inventor and the BLE-Nano board. The BLE-Nano board is basically an Arduino Nano with an … Continue reading Bluetooth communication between an App built with App Inventor and the BLE-Nano board
This page explains the use of the TCS3200 colorsensor and shows how to create a small holder for it, which can be mounted on the Rover Car. It is also possible to just use the holder (without connecting it to the car) as it will make it easier to use and shields it from ambient … Continue reading Using the TCS3200 color sensor
In this example we will control a RGB LED from an Android App via a Bluetooth connection. A HM10 BLE Bluetooth module is connected to an Arduino Uno. This tutorial assumes you already have some experience with Arduino. If not, you might want to follow a basic tutorial and/or install the Arduino software (the IDE). … Continue reading Control an RGB LED from an Android App via Bluetooth
