WS2812B vs. WS28123 – Determine the type of LED strips
There are many different types of LED strips out there. What type do you have? This post gives you hints on how to determine this. LED types These are the types of SMD LED components that you might find on LED strips: 3528: single color, non-addressable, very low power 2835: single color, newer than 3528,Continue reading “WS2812B vs. WS28123 – Determine the type of LED strips”

Publish accelerometer sensor data on MQTT from ESP8266
Introduction This tutorial adds to the previous one, in which we wrote a sketch for a Wemos D1 mini (ESP8266) board, to read out and print accelerometer data. Now, we want to publish this data to an MQTT broker in the local network via WiFi. Prerequisites For this tutorial, we will switch to PlatformIO. Also,Continue reading “Publish accelerometer sensor data on MQTT from ESP8266”

Read accelerometer sensor with ESP8266
What parts do we need for this tutorial? ESP8266-based board (e.g. Wemos D1 mini) Accelerometer IC (e.g. MPU-9250, which is a 9-axis sensor) A breadboard Some jumperwires Introduction Welcome to this tutorial where we will explore reading measurements from an accelerometer sensor and displaying them on the serial console. An accelerometer is a device thatContinue reading “Read accelerometer sensor with ESP8266”
