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 Android…
This tutorial extends the tutorial of a temperature sensor with a display, and adds data logging to that. This can be realized by logging to an SD card (part 1), by logging to a website (via Wifi) (part 2) or…
Through this tutorial you become familiar with developing a Python application with a graphical userinterface. We will create an App which can display weather data from various weather stations. Data will come from an online xml service providing weather data.…
Through this tutorial you become familiar with developing a Python application with a graphical userinterface. We will create an App which draws some basic shapes. The color of one or more of the shapes can be changed by entering a…
In this tutorial you learn to build a temperature sensor and connect it via Bluetooth with an App. It uses a DHT11 temperature & humidity sensor and Bluetooth communication with your phone. For this we will use a Raspberry Pi…
This short tutorial introduces the VL53L1X Time-of-Flight (ToF ) distance sensor and hook it up to an Arduino Nano. Further directions: If you bought it like this: You will first have to solder the header pins. Connect the sensor Because…
In a previous tutorial “build a distance sensor with an alarm” we used an Arduino Nano (coded in a C-variant). Now, we will do the same with a Raspberry Pi Pico and CircuitPython, a version of Python which runs on…
Through this assignment you become familiar with developing a Python application. We wil create an App in which you can input text and then show that text as part of a message in the App. Python is renowned for its…
In this tutorial, we will create a simple text-based calculator. It’s meant to practice basic Java syntax, like println(), if- and basic arithmetic. The resulting calculator can only do the 4 basic operations and it does not recognize fractions. It…
