The CJMCU-530 is a breakout module featuring the VL53L0X by ST Microelectronics which is a laser-ranging sensor for distances of up to 200cm. The module works without problems with the ESP8266 which makes it an interesting option for your next IoT project.
This post describes how to connect the 2.7″ ePaper display development module from Embedded Artists to the ESP8266. ePapers are very interesting in the IoT field since they only require power during the update. Depending on the type of display they can then maintain the image …
There are many applications for distance measuring: in robotic as a cheap way to sense the environment and detect obstacles, in IoT applications to measure fill levels of containers containing food and in alarm systems to detect intruders – to name just a few.
The “ESP8266 OLED SSD1306″ is an open source library which allows you to control those pretty OLED modules from our beloved ESP8266 module. Fabrice Weinberg cleaned up all the ugly pieces of code which I initially wrote caused by my near C/C++ illiteracy. He also added support for …
The sensor I’m going to talk about here is a very powerful one. And you actually might have a very similar one in your home somewhere. The DF Robot Positioning IR Camera uses the same or similar module that is built into the Nintendo Wiimote …
The ESP8266 is all about Internet of Things, right? So lets start sensing something in the real world! What about (human) presence in your apartment? There are various ways to do that but one of the most common type is sensing with pyro electric sensors …
Almost 20 years ago when I studied a few semesters of electrical engineering at the famous ETH in Zurich I had a lecture about the basics of digital electronics. And I remember the professor doing many practical demonstrations such as drilling holes into a CD …
The ESP8266 took the hearts of the IoT and Do-It-Yourself community by storm, due the very attractive price, its internet connectivity and due to the relatively rich amount of available GPIO pins. But an internet connected device is not worth much without means to interact with …
If you want to engage with your ESP8266 into robotics there is now an almost ready-to-go solution: the NodeMCU Motor Shield. If my research is correct then it was the Doctors of Intelligence & Technology (http://doit.am/) who created it and also are offering some LUA …
Twice a year the company I work for (Netcetera) organizes a retreat for programmers, usually in the mountains. In the Spring issue this year we went to a resort in a beautiful mountain region. Inspired by the wonderful landscape I managed to write a library …
