The standard way to connect a serial port (RS232) to an Arduino (or any 0V/5V based serial interface) is to use a dedicated IC like MAX232A. With this IC, you don't need a 9V battery like with my ...

How to connect an Arduino to a real serial port (RS232) For the challenge, I wanted to send data from my computer's real serial port (RS232 9-pin connector). For that, I created an adaptor circuit ...

Who'd Thunk It? Arduino and PLCs Hook Up Via RS232 and Modbus There is a thriving online developer community using RS232, Arduinos, and PLCs to build industrial and home automation systems on the ...

This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

This research develops the maximum power point tracking (MPPT) device by Arduino ATmega2560 and express the values on 3.5-inch display. Moreover, all data recor ...
