Object counting with distance sensors
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
Create a connected distance sensor with an ESP32 module
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
Using an Optical (IR) sensor with Arduino
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
Use an OLED Display with Arduino
Information on how to use an 0.96 inch OLED Display (128*64 pixels) with an Arduino. This is an i2c module, which makes it easy to connect as it has only 4 wires. It is assumed you have installed the Arduino IDE and have some basic understanding of using electronics and wiring a breadboard. In addition, … Continue reading Use an OLED Display with Arduino
Use DHT11 temperature and humidity sensor with display
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
Sounds and music with Arduino
This article highlights four different ways you can make sounds with the Arduino or play music. It starts with the easiest one: (1) adding a small buzzer, then (2) a standard loudspeaker, then (3) using your smartphone as the speaker via an connected app. It ends (4) with using an MP3 module. A tutorial which … Continue reading Sounds and music with Arduino
Using the TCS3200 color sensor
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
Using various displays with EVShield
Information on how to use displays in combination with the EVShield. Small (oled) displays can be a great addition to a robot powered by an EVShield, like the Rover. It can be used to display all kinds of information about the status of the robot, like the battery voltage, speed etc. The Lego display is … Continue reading Using various displays with EVShield
