This tutorial uses the Arduino Nano, but you may also use an Arduino Uno. You might need the Arduino Nano pinout diagram or an other diagram for your particular model of Arduino. We are going to use the diagram below to build it. But if you are inexperienced each step is explained in detail. First, … Continue reading Use DHT11 temperature and humidity sensor with display
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
This tutorial describes how to Use App Inventor to build an App which can read the online values of a connected sensor. For this, it uses a WebViewer Component and a Clock to refresh values. This is part 2 of a series, the first part, “Create a connected sensor” can be found here. This second … Continue reading Build an App with App Inventor which can display values of a connected sensor
This tutorial demonstrates how to build a simple sensor and publish its values online (on a web server) using an ESP32 module. We will build an Arduino sketch which will read the sensor values, connect to WiFi, connect to a website and publish the values on the website. The published values can then be used … Continue reading Tutorial: Create a connected sensor
I have written a class for the HiTechnic Colorsensor, which makes it possible to use this sensor with the EVShield. The example sketch requires the class EVs_HTColorSensor which you can download here. Extract the two files from the zip-file into the EVShield library folder, eg. Documents\Arduino\libraries\EVShield. Now you can use the sensor, as in this … Continue reading Using the HiTechnic Colorsensor with the EVShield
By utilizing the Arduino-bit and the Proto-bit, all kinds of electronic circuits and components can be connected to a Littlebits circuit. In this example, we connect an Ultrasonic sensor to the Arduino-bit with the Proto-bit. The distance measured by the Ultrasonic sensor will be displayed on the Number-bit. This example is based on the Bat … Continue reading Build a distance-sensor with LittleBits
In this tutorial, we are going to create a gamecontroller which can control the game using movements. By tilting the gamecontroller, you can control the movement of the basket. We will extend the game made in the previous tutorial. Carrying out the assignment Realizing the gamecontroller can be done in 2 ways: Using the MPU-6050 Accelerometer … Continue reading Tutorial: Create a gamecontroller for the catch-the-ball game
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
The BLE-Nano as sold here is a combination of a traditional Nano with a Bluetooth BLE module, based on the CC2540 BLE bluetooth chip. The Bluetooth module is directly connected to the TX, RX pins of the Arduino (pins 0 and 1). There is a troubleshooting section further down on this page! This is the … Continue reading Introduction to the Arduino BLE Nano
Learn how to build a remote controlled Rover car with Lego Mindstorms, with an Arduino ‘brain’, which can be remote controlled via Bluetooth with a phone. This guide uses parts from the Steering rover example on nxtprograms.com. It is also inspired by the NXT Dune Buggy.Lego parts shown here might be of different color depending … Continue reading Lego: Build remote controlled Rover car with Arduino brain
