Prototyping in a rush? No time for physical prototype? Simulate it!

Learn more about simulating a physical prototype. Wokwi is a great simulator that you can use to build your electronics projects online, without the need to get components, wire them on a breadboard and then test. If you combine it with Chat GPT to do the coding, you can have your prototype up-and-running in literally … Continue reading Prototyping in a rush? No time for physical prototype? Simulate it!

Breadboard with temperature sensor, display and Raspberry Pi Pico

Tutorial: build a connected temperature sensor with a Raspberry Pi Pico W

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 Pico W, the Wireless edition of the Pico. It consists of the following steps: This … Continue reading Tutorial: build a connected temperature sensor with a Raspberry Pi Pico W

Sensor with separate header pins

Using the VL53L1X Time-of-Flight Distance Sensor

This short tutorial introduces the VL53L1X Time-of-Flight (ToF ) distance sensor. For more tutorials on distance sensors, including various applications, look here. You can buy this sensor here. 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: … Continue reading Using the VL53L1X Time-of-Flight Distance Sensor

Tutorial: Create a gamecontroller for the catch-the-ball game

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

Tutorial: build a connected temperature sensor

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

Tutorial: build a distance sensor with an alarm

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

BLE-Nano with RGB LED

Bluetooth communication between an App built with App Inventor and the BLE-Nano board

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

Countdown timers and executing tasks in parallel on an Arduino

The examples in this article use an OLED display. Countdown timer example In its simplest form, a countdown timer can be coded like this, using the loop() for repetition (no for- or while-loop needed!): Download the sketch: oled_display_countdown_start_button.ino Full simulation including breadboard on Wokwi: This will countdown from 10 to 0 in ten seconds after … Continue reading Countdown timers and executing tasks in parallel on an Arduino
