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 microcontrollers. If you are more interested in programming the Pico with the Arduino IDE (in … Continue reading Tutorial: build a distance sensor with a Raspberry Pi Pico and CircuitPython
Introduction to Arduino and programming . Practicals which use this tutorial have an introductory presentation (pdf). We will build a temperature sensor in this tutorial and connect it with an App. It uses an DHT11 temperature & humidity sensor and Bluetooth communication with a phone. We use a BLE-Nano here, but you can also use a regular Arduino … Continue reading Tutorial: build a connected temperature sensor
Introduction to Arduino and programming . There is also a “quick walk-through video” of this tutorial. My practicals which use this tutorial have an introductory presentation (pdf). We will build a distance meter in this tutorial. It uses an ultrasonic distance sensor to sense the distance to an object nearby. It consist of the following steps: … Continue reading Tutorial: build a distance sensor with an alarm
Learn how to count products on a conveyor belt with a distance sensor. This article explains how to use a distance sensor for counting objects. In this case, we have a conveyor belt with products, which we will count. This article is part of a lecture on use of sensors in Industry 4.0. The setup … Continue reading Object counting with distance sensors
This short tutorial introduces the ESP32 module (a Lolin32 Lite) and connects an HC-SR04 Ultrasonic sensor. The entire prototype will be powered by a battery and sent its data to a webserver via Wifi. It is assumed you have installed the Arduino IDE and have some basic understanding of using electronics and wiring a breadboard. Although in … Continue reading Create a connected distance sensor with an ESP32 module
Assignment: design, build and test a “product counter” which is able to count various products passing by on a conveyor belt. The counter should have a display which displays: a) measured distance, b) whether there is a product in sight (or not) and c) the number of counted products. Submit your results using the form … Continue reading I4.0 Sensor practical
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
To quickly change the Spike into an Explorer robot, you can strip legs, claws and tail, leaving the chassis as a basis to build the Explorer robot.Then add wheels, a bumper with touch sensor and an ultrasonic sensor mounted on a motor. You can also build the Explorer from scratch, then you can follow the … Continue reading Lego: use Spike chassis to build Explorer robot
This guide explains how to build the Lego Mindstorms model “Spike”, powered by an Arduino and an EVShield. The original version of the Spike is powered by a Lego NXT. Requirements EVShield, Arduino Uno, Battery holder (+6 AA batteries) Lego Mindstorms kit (can be either NXT or EV3) Introduction To make a sturdy, compact solution … Continue reading Lego: Build Spike with Arduino brain
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
