This is a quick guide to getting our HC-ESP presence detector up and running with Home Assistant. The module comes preinstalled with ESPHome firmware so getting it up and running should be a trivial process and the only prerequisites you will need are a smart phone (or desktop computer with Wifi) and a Home Assistant…
Hello everyone. This time we’re going to be making the Simon Says game from our popular Arduino Starter Kit. If you have the kit, you can follow along with the video, if not, we sell all the bits as a bundle here. As well as the bundle above, I’m using the Arduino compatible Hobby Components…
In this video I’m showing you the mLink DHT22 sensor is a serial (I2C/IIC) temperature and humidity sensor module. It adds the ability of your microcontoller/Arduino to measure temperature (in oC) and relative humidity (%RH) to 1 decimal place using only its I2C interface. It is compatible with other mLink or standard I2C modules allowing…
In this second part we’ll be adding an LCD screen to display the current temperature and relay state so that we can monitor the controller we created in the last video without it being connected to a computer. If you’ve not already followed part one check out the blog post and video here. Once set…
In this project we’ll show you how to create your very own temperature controller using an Arduino board and some mLink I2C modules. We’ll break this project into two parts with the second part being optional depending on how complex you’d like your controller to be. In the first part we’ll use a mLink NTC…
I’ve added a few videos recently for the mLink range of modules and in each of those I’ve explained how to add the library to the Arduino IDE – I figured it might be worth doing a video for that, so that I can reference it rather than keep filming the same thing. Links mentioned…
In this video I’m showing you the mLink Character LCDs which are serial (I2C/IIC) LCD displays available in either 16 column by 2 row (16×2), or 20 column by 4 row (20×4) options. Because they use a standard I2C interface they’re compatible with most microcontrollers including Arduino, they’re addressable, the address can be changed in…
Our latest video covers the mLink NTC temperature sensor. This is a serial I2C module that interfaces to a wired remote NTC sensor probe. The module continuously takes measurements and provides the results in centigrade via the I2C interface. The probe itself is on a 2 metre wire, so it’s quite a long one, making…
In this video I’m going to show you the mLink relay modules. These are a range of 5V relay modules that were designed to be controlled either manually or via a microcontroller. For manual control there’s a set of digital pin(s) that can be toggled to directly control the relay. For controlling via a microcontroller…
Our latest video covers the mLink TMP36 Sensor Module. The mLink TMP36 module is a tiny serial (I2C/IIC) device that includes a precision TMP36 temperature sensor. This alows the module to measure temperatures over a wide range of -40 to 125oC. The module continuously takes measurement from the TMP36 sensor and provides the result as…
