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. It takes the basic steps to connect electronic components and programming the Raspberry Pi Pico in Python. It uses an 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
