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…
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…
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…
This is a demo project for the new Piksey Atto. We use the TTP224 touch IC and the APDS-9960 gesture module to control a computer. We upload a sketch to the Atto which makes it act like a USB keyboard and it then sends the appropriate keycodes depending on the Read more…
I wanted to add some RGB to my work desk and I decided to create an RGB LED coaster using the common WS2812B RGB LEDs. I couldn’t find a board that was small enough for this and so I decided to design a new board which is now being released Read more…
This is a demo video for the Piksey Atto. We learn how to use it as a MIDI device and control tracks in Ableton Live 10 Lite. We use a breadboard along with momentary switches and you can also use an Arduino Leonardo for this project. Step 1: Watch the Read more…
Since Christmas eve is just a week away, I decided to build a simple RGB decorative light using an Arduino Nano and WS2812B LEDs. We use some plastic containers/jars to improve the visual effect. This video uses 5 LEDs but this can be increased to suit your needs. You can Read more…
In this post, we will learn how to build a simple yet useful air quality sensor. We will use the SGP30 sensor along with the Piksey Pico, though the sketch will work with pretty much any Arduino compatible board. The video above talks you through the importance of such a Read more…
As a follow up to the room thermometer project, we write a sketch that communicates with an online weather service and displays the weather. Step 1: Watch The Video Since this project requires you to set up and obtain an API key along with other tasks, I would recommend you Read more…
We learn how to build a room thermometer using the DS18B20 sensor and an OLED module. Step 1: Watch The Video The video contains all the information you need about the build and I highly recommend watching it first to give you an understanding of how it all comes together. Read more…
