Understanding The Number on Ceramic Disc Capacitor’s

What does the capacitor number means?Ceramic disc capacitors come with a 3 digit number printed on them, this number is used to determine the capacitors capacitance. As the ceramic disc type capacitor's are small, they are measured in picoFarads (pF). Calculating the...

Introduction To ESP32

What is ESP32?Anyone who works with Electronics & IoT knows how powerful the ESP32 boards are! ESP32 boards are the successor of ESP8266. It is just like an Arduino board, but with built-in Wifi, Bluetooth, temperature sensor, touch sensor and much much more!...

Introduction to Arduino interrupts

As we all know, the Arduino has 2 basic functions. The setup function and the loop function. In a practical sense, we usually go with the expensive microcontrollers instead of analog components when want to read values and take decisions based on the data coming from...

Basic Linux Commands

Here are some basic Linux commands to get you up and running, or a quick cheat sheet. Great for when working on a Raspberry Pi or any other single board computers which use Linux commands such as Beagleboard / Beaglebone, Asus Tinker Board and many...

Introduction to NodeMCU

NodeMCU is exactly something that the following image indicates. NodeMCU is like a programmable Arduino board, but a lot more than just that. It has inbuilt Wifi and a lot more which I will be covering here and also show you all how to program it. What is...

Using Shift registers with Arduino

As we all know, Arduino or any micro-controllers that exist have a limited number of pins. An Arduino has 14 digital pins. So, what if we had to control 7 LEDs or drive something else using it? We would have to use 7 individual digital pins. That is quite a big number...

Getting started with Arduino: How to setup Arduino

What is Arduino? The Arduino project was born at the “Interaction Design Institute Ivrea (IDII)” in Ivrea, Italy. It is an open-source company, project and user community that designs “single board micro-controllers” and “micro-controller” kits for building devices...
