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
Example of use of the MAX30102 heartrate sensor with MicroPython on a Raspberry Pi Pico. This example is based on this Maxim MAX30102 driver. The MAX30102 is an integrated pulse oximetry and heart-rate monitor biosensor module. Check out its datasheet here. The driver used is written for the MAX30102 and might work for the MAX30105 also. … Continue reading Setup a heartrate sensor with a Raspberry Pi Pico
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…
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
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
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
