This project combines two examples: We will use a Seeed Studio XIAO which is a small microcontroller, but this can be done with any Arduino or ESP module you have at hand. For code generation, GitHub Copilot is used. Setting up the circuit Connect the SCL & SDA pins of the VL53L1X sensor to those … Continue reading Simulation of anxiety: pulsing rainbow heartbeat pattern on a LED strip that intensifies when something get closer… →
In this tutorial, we will build a laser distance Sensor with a Raspberry Pi Pico and CircuitPython, using a VL53L1X Time-of-Flight (TOF) sensor. In this tutorial you will learn to build a distance sensor. It takes the basic steps to connect electronic components and programming the Raspberry Pi Pico in Python. It uses an laser … Continue reading Tutorial: build a laser distance sensor with a Raspberry Pi Pico →
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 the sensor uses I2C its wiring is simple: It’s operating voltage is 3.3V or 5V, … Continue reading Using the VL53L1X Time-of-Flight Distance Sensor →
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 . There is also a “quick walk-through video” of this tutorial. My practicals which use this tutorial have an introductory presentation (pdf). Further directions: 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 … 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 →
This short tutorial introduces the Optical (infrared) distance sensor (Sharp GP2Y0A21YK0F). It is assumed you have installed the Arduino IDE and have some basic understanding of using electronics and wiring a breadboard. If you want to learn more or if anything is unclear, check out this extensive tutorial. Although in this example we use a display, you can … Continue reading Using an Optical (IR) sensor with Arduino →
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 Smart Industry 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 →
