And the board features 20 digital input/output pins, a 16 MHz crystal oscillator, a micro-USB port, an ICSP header pins, and a RESET button. Arduino Micro pinout, specifications, schematic, and datasheet is given below. … Read more
Arduino Nano 33 BLE sense is a microcontroller of the new generation launched by the Arduino company in July 2019. The board comes with a very powerful processor nRF52840, a 32-bit ARM® Cortex™-M4 CPU running at 64 MHz. The board also features a lot of sensors that were not present in the previous nano board … Read more
An ultrasonic sensor measures the distance of an object by emitting ultrasonic sound waves. The reflected waves from the object are received by the sensor and are converted to corresponding electrical signals. Numerous ultrasonic sensor projects are available on the internet. But here, we present the best five Arduino ultrasonic sensor projects. Intruder Alarm Project … Read more
In this post, I will show you how to change the PWM frequency of Arduino Nano. PWM or pulse width modulation is a method of reducing the output voltage by switching the input voltage ON/OFF at a very high frequency. Here reducing means getting the average voltage value at the output. Arduino Nano PWM pins … Read more
The Arduino Leonardo is a microcontroller board based on the ATmega32u4 microchip. The Atmega32u4 comes with a built-in bootloader, which makes it convenient to flash the Arduino board with our code. It consists of a total of 20 digital I/O pins (of which 7 can be used as PWM outputs and 12 as analog inputs), … Read more
The Arduino Mega is an open-source development board that is developed by the Arduino company. It is based on the Microchip ATmega2560P by Atmel. The Atmega3560P is an 8-bit microcontroller that comes with a built-in bootloader, which makes it very convenient to flash the board with our code. Atmega 2560P based Arduino Mega pinout and … Read more
