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 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
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
