Step 1: Watch the Video The video above goes over the entire process of creating a digital timer and we cover some additional information that is not present in this post. I’d recommend watching it first before proceeding. Step 2: Set-Up the APP Start by downloading the app from the Read more…
Step 1: Watch the Video The video above gives you all the information you need to build this yourself. This post will only provide the final configuration file that can be used as a starting point. Step 2: Wire the LEDs You can use the reference wiring diagram above to Read more…
In this post, we learn how to use InfluxDB for long term sensor data storage and we use Grafana for data analysis. This is part of the home automation series where we learn how to set up and use Home Assistant so all this will be done using Hassio. Step Read more…
I was pleasantly surprised when I decided to try to add some DIY sensors to home assistant. Using ESPHome is extremely simple and in this post, we will learn how to control a GPIO pin and also obtain temperature & humidity data from a wireless node, by using Home Assistant. Read more…
This post will tell you everything you need to know about MQTT communication which will enable you to use it communicate between devices. We add an LED to the Arduino Nano 33 IoT board and this LED is controlled remotely from a switch that is connected to a WeMos D1 Read more…
A couple of weeks ago, we learned how to build an online weather display system that obtained weather information for a particular city and displayed it on an OLED module. We used the Arduino Nano 33 IoT board for that project which is a new board that has a lot Read more…
We learn how to build a cute little digital clock that communicates with NTP servers and displays network or internet time. We use the WeMos D1 mini to connect to a WiFi network, obtain the NTP time and display it on an OLED module. The video above talks you through Read more…
In this post, we build a beautiful RGB cellular lamp that can be controlled over WiFi. The control page consists of a colour wheel which allows you to quickly change colours and you can also specify the RGB values directly to create a total of over 16 million colour combinations. Read more…
