Jul 16, 2020 · Port expanders can be used to create extra GPIO pins on the Arduino. In this tutorial, we will learn how to use port expanders by building a project using the MPC23017 port expander to create two additional 8-bit ports and read and write to them using I …

The MCP23017 is the all-singing-all-dancing Arduino port expander with 16 I/O pins and it gives you virtually identical pin capability to the existing pins of a microcontroller. They can be individually set to input or output and you can enable an internal pullup (also individually).

Sep 16, 2016 · A solution is to use the free Virtual Serial Port Emulator to tunnle a serial port. Now you can use this ports with Virtual Breakboard. You can find a good tutorial how to do it in this video.

CONNECTING MULTIPLE SENSORS TO ONE ARDUINO UNO SERIAL PORT: In this tutorial, we will be expanding a single Arduino UNO UART (Rx/Tx) serial port so that multiple Atlas sensors can be connected. The expansion is done using 8:1 Serial Port Expander board.

void open_port(uint8_t _port) { //this function controls what port is opened on the serial port expander if (port < 1 || module_count > 8)_port = 1; //if the value of the port is within range (1-8) then open that port.

Sep 11, 2015 · Hi all, I've just bought this: 8:1 Serial Port Expander | Atlas Scientific? and I wired it and it's working with the demo from the page (with altsoftserial lib, I can get values from sensors and everything. The problem…

Oct 29, 2019 · The PC simply send strings to the arduino via a serial connection. An embedded software on the arduino turns these strings into a proper command to operate the cards. I am not worried about the communication between the PC and the arduino.

May 20, 2019 · With the Atlas Scientific 8:1 Serial Port Expander you can quickly add 8 more ports to your Arduino. Connect two serial port expanders and have up to 16 serial ports! For more information,...

Sep 24, 2024 · Simulation -- Reads a digital pin and prints the results on the serial port. Simulation --Ramp LED PWM up and down based on delay (). Simulation -- reads an analog input, converts it to voltage, and prints it to the serial port. Simulation forum discussion -- Some ways are easier and safer than others.

This Arduino sketch provides a basic simulation of a Speeduino ECU serial interface, generating and transmitting simulated real-time engine status data. The simulation includes a simplified engine model and supports the 'A' command for real-time data.
