In this tutorial, we will see the Pinouts of both NodeMCU board as well as the ESP-12E Module, which is the base board for NodeMCU. The ESP12-E Pinout will be helpful if you are developing your own hardware and understanding the NodeMCU Pinout is very useful if you are working…
For a passive RC differentiator circuit, the input is connected to a capacitor while the output voltage is taken from across a resistance being the exact opposite to the RC Integrator Circuit. A passive RC differentiator is nothing more than a capacitance in series with a resistance, that is a frequency…
There are many different Types of Resistor available for the electronics constructor to choose from, from very small surface mount chip resistors up to large wirewound power resistors. The principal job of a resistor within an electrical or electronic circuit is to “resist” (hence the name Resistor), regulate or to set the flow…
In the previous RC Charging and Discharging tutorials, we saw how a capacitor has the ability to both charge and discharges itself through a series connected resistor. The time taken for this capacitor to either fully charge or fully discharge is equal to five RC time constants or 5T when…
For a passive RC integrator circuit, the input is connected to a resistance while the output voltage is taken from across a capacitor being the exact opposite to the RC Differentiator Circuit. The capacitor charges up when the input is high and discharges when the input is low. In Electronics, the…
In this tutorial, we will learn some basic Digital Input and Digital Output operations on ESP8266. I chose the NodeMCU board for demonstrating ESP8266 NodeMCU Input Output operations using LED as a Digital Output device and a Push Button as a Digital Input Device. ESP8266 NodeMCU Input Output Operations If…
