Many modern microcontrollers like ESP32 , Raspberry Pi Pico 2 , STM32 Nucleo-F401RE , STM32F103C8T6 ("Blue Pill") and modern Teensy boards operate primarily on 0V to 3.3V logic while standard peripherals—such as 16x2 I2C LCDs and 5V…
The ESP32 devkit v1 and alike ESP32 boards have 25 usable GPIO pins exposed, many of which are input only pins (4 pins which can only be used as digital input pin), many are strapping pins (5 pins which are used for boot control and should not be se…
Usually if we want to use Arduino with 16x2 LCD to display some message, usually 6 I/O pins of Arduino are required as illustrated in the blog post Arduino Keypad and LCD Interfacing with Code . However, sometimes we need those I/O pins for interf…
Here it is shown how to expand Arduino's I/O using MCP2307 I/O expander IC with example of a button-controlled LED. The MCP2307 is a 16-bit input/output (I/O) expansion chip manufactured by Microchip Technology that can be used to add extra inpu…
The following circuit diagram shows how you can connect household AC lights and appliances to your microcontroller ( ATmega328P , ATmega32 , PIC, ATC8051 etc) or prefabricated readymade microcontroller boards like Arduino ESP32, Raspberry Pi Pico 2…
The magnitude and form of signal from sensors such as microphone, gas sensors, piezo sensors are not in the form that can be sensible be read by the Arduino input pins. And so the sensor signal are often required to be conditioned, transformed into …
What can information theory reveals about social interaction? Moreover, how can information theory provide semantic meaning? In classical information theory, Entropy measures average uncertainty or information content, typically quantified in bits/s…
Apache RTR 160 is an excellent sport bike for city area. It has 160cc (cubic centimeter) engine which is enough for city area. The Apache RTR 160 is widely famous for having exceptional pickup . In fact, the "RTR" in its name stands for …
