Digital Inputs and Digital Outputs on the NodeMCU ESP8266

Digital signals are in the form of 0's and 1's, and the ESP8266 has 17 GPIO pins but we can only use only 11 of them because the rest are connec

So as we move to the modern day we are talking more about wireless systems, wireless communication and everything that operates and connects the inte

Introduction Water detector / Rain detector / Water Drip detector all have the same concept and would be the same project. Well you just got to ch

In this project we are going to create a graphical representation of the signal amplitude. The higher the amplitude the more number of LEDs will be t

While we read about digital inputs in the last post, we are going to talk about Analog input. Arduino is a digital tool but can still interpret da

Make the Arduino into a temperature sensing device. Now there are various temperature sensors based on your requirement you should decide which one s

Switch is a device that allows the flow of current through it. It can also break the circuit, so it is majorly used in circuits where we need to brea

Lets put together two of our modules, i.e. the DHT11 and the LCD16x2. What happens when we get both the modules together? We get a mini-weather s
