Example of use of the MAX30100 heartrate sensor with an Arduino. This example uses the Arduino-MAX30100 library. The MAX3010x series are integrated pulse oximetry and heart-rate monitor biosensor modules. Check out its datasheet here. If you have the MAX30102 or MAX30105 sensor, consider using a more recent library like the official Sparkfun library (see below). There … Continue reading Setup a heartrate sensor (MAX30100) with an Arduino
This tutorial will introduce you to coding MicroPython on a Raspberry Pi Pico. MicroPython is a version of Python that runs on a microcontroller, like the Raspberry Pi Pico. To get started, you need an editor that helps you to write code in Python and can connect to the Raspberry Pi Pico. Two options for … Continue reading Getting started with MicroPython on Raspberry Pi Pico
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 Android Studio. Older versions of this tutorial: If you have and Arduino, that can also work … Continue reading Create an RGB Led controller App
This tutorial extends the tutorial of a temperature sensor with a display, and adds data logging to that. This can be realized by logging to an SD card, to the memory of the Raspberry Pi, or by logging to a website (via Wifi). The first part is logging to an SD card. Part 1: Data … Continue reading Data logging with the Raspberry Pi Pico W
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. Starting with the basic steps to connect electronic components and programming the Raspberry Pi Pico in Python. Next, use a laser … Continue reading Tutorial: build a laser distance sensor with a Raspberry Pi Pico
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!
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
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
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
