The Smart Gardening system project was my attempt at exploring IoT and edge computing with Lego to see what I can create from scratch. Shortly after the project went live, I realised that there are a limited number of analog pins available on the Arduino that I can use with…

In the previous articles, we covered the implementation of a water pump station as a separate module and did some discovery works on adding WiFi capability for the Soil Moisture Monitoring system. They can be found here and here respectively. In this article, we will continue to look at integrating…

In the previous articles, we covered the development of a soil moisture sensing system and the addition of a WiFi module so that the soil moisture information could be sent out. Phase 1 of the project is covered here while Phase 2 (Part 1) is covered here. …

In phase 1 of the project, we implemented a soil moisture monitoring device that was capable of only telling us the moisture level of the soil through an OLED display and buzzer. For phase 2, we will be implementing WiFi connectivity for the Arduino so that it could start sending…

I have several pots of Dracaena Sanderiana (Lucky Bamboo) at home and I struggle with watering them. The genus loves moderately moist soil. Overwatering will lead to root rot and them turning yellow while under-watering can lead to dry soil and the plant can die too. This is why I…

With the COVID-19 pandemic, temperature checking before you enter a premise is a necessary step to ensure you are well and help keep others safe. In Singapore, it is a requirement from the government. One of the most common way is to use a handheld digital thermometer to find out…

Software engineers who worked extensively with Java technology might have come across and/or use Spring Framework for their projects (professional or personal). In 2013, the Spring Boot project was started to simplify the deployment of spring-based web application. Personally, I have used it at the beginning of my programming career…

Software testing is an important step during its development lifecycle. It ensures that the software function or operate as what the stakeholders wanted, which contribute to the perception of quality software. …
