The most common devices around your home may not have smart capabilities and sometimes, you might simply want to switch them ON/OFF at predetermined times. We have previously looked at the Sonoff S26 that can be used to do this and we now take a look at another popular solution Read more…
The most common devices around your home may not have smart capabilities and sometimes, you might simply want to switch them ON/OFF at predetermined times. In this post, we take at one popular solution that uses the Sonoff S26 smart socket that is based on the ESP8266. Since it does Read more…
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…
After getting an understanding of how IR sensors work, we now learn about ultrasonic sensors. These have a much higher detection range and can be used for various purposes – from simple object detection to mapping surroundings. This post gives you all the information you need to know in order 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…
We continue our robotics adventures by making use of the theory that we learnt last week and building a simple 2WD rover using an Arduino. Step 1: Watch The Video The video above goes over everything you need to build this simple rover. This post will only provide the wiring 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…
We continue with the Pi Zero dashcam project and in this post, we take care of file management while also adding some enhancements in the process. This project is almost complete and we will be carrying out road tests in next week’s post/video. Step 1: Watch the Video There have 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…
