To test I plugged in two serial devices, a generic USB-to-RS232 adapter and a Blu Samba Q cellphone. One of them appears on the sheet SerEnum but the other appears under USBSER, which makes me assume that depending on how it is programmed the device driver, service name is arbitrary and therefore its location in the tree HKEYLOCALMACHINE.

Many Arduino projects have the need to send data to a PC running a program for data aquisition and visualisation. Lazarus is highly suitable for developing such programs, i.e. to build the PC-sided counterpart of an Arduino project.

Serial through the USB port. I`ll have a look at the USB port tonight and connect a Propeller board to see if I can see a FTDI device on the port.
For Lazarus developers Arduino opens a whole new world of smart physical sensors and actuators for monitoring, control and data acquisition.
The fpc compiler is even capable to compile programs for Arduino boards itself.

Currently (2017) most Arduino boards carry microcontrollers of the AVR family (Atmega). An other popular arduino board carries a STM32 (ARM Cortex). For both microcontroller families there are fpc compilers available. Programming Arduino with FPC of course doesn't mean to use the arduino ecosystem with just a different language. Nevertheless arduino libs (C++) can be used in fpc programms, but mixing languages obviously is an advanced topic.While compilation the fpc creates a .hex-file (binary), this can be loaded to the microcontroller, arduino board respectively, using a programming software by choice. AVRDude e.g. also supports program upload using the Arduino bootloader.

Serial Port For Lazarus 2017
The following section describes how your Lazarus/FPC application can communicate with Arduino boards, no matter whether fpc or arduino is running on the arduino board. Advantage and disadvantage of the serial dilution agar plate procedure.
