## Python for beginners

Hi, if you are embarking on a journey to start learning Python, or you just need to refresh your mind, perhaps from after a long summer break ;), this is the right place to be! At Clounce, we prepared a number of Jupyter notebooks to help you started (see link below). Each notebook focuses on … Continue reading Python for beginners

## Conditional highlighting of a column in Excel

Some years ago, we saw how one can highlight a row in an Excel table based on a cell value. Today, we are going to look into how to highlight a column instead of a row. It is quite similar, so I will only focus on the change required and explain the functions used. To … Continue reading Conditional highlighting of a column in Excel

## Simple Aquarium Temperature Sensor

It has been a while that I wanted to leverage the power of ESP-8266 NodeMCU to monitor my aquarium. My first experiment is to read the water temperature every x interval and upload it to ThingSpeak. For this experiment, I need: ESP-8266 NodeMCU; DS18B20 waterproof sensors, which I bought from Amazon; 4.7kΩ resistor. The setup … Continue reading Simple Aquarium Temperature Sensor

## Applying De Morgan’s First and Second Laws using digital TTL ICs

Today, we are going to carry out a simple experiment using logic ICs to apply De Morgan First and Second Laws. They state that: – the negation of a disjunction is the conjunction of the negations – the negation of a conjunction is the disjunction of the negations Wikipedia Let’s keep the theory in the … Continue reading Applying De Morgan’s First and Second Laws using digital TTL ICs

## BCD Switch

Last time we started to look into digital electronics. One handy building block for our experiments is the facility to provide input values to our circuits. An easy way to do is by using DIP switches but I find it always difficult to toggle the positions of the switches. Also, sometimes we want to provide … Continue reading BCD Switch
