Pulse Width Modulation with NodeMCU ESP8266
Posted on by Rolan Gaspar Pereira
Digital signals have two positions: on or off, interpreted in shorthand as 1 or 0. Analog signals, on the other hand, can be on, off, half-way, two-t
Digital Inputs and Digital Outputs on the NodeMCU ESP8266
Posted on by Rolan Gaspar Pereira
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
Semiconductor Diodes: A Simple Introduction to their Basics and Functions
Posted on by Rolan Gaspar Pereira
However, unlike a resistor, a diode does not behave linearly with respect to the applied voltage as it has an exponential I-V relationship and th
