The TS is a commercial electrician, not a hobbyist. And the fact that possibly the cable and the other accessories might be included does not change the fact that they will be required. And I did neglect the effort to program the device, which from my observation, they choose to use different words for most functions, so the learning curve will not be trivial. Also, the intercom system already includes a 24 volts AC supply, so that will not be an extra.Me thinks thou doth protest too much. A little exaggeration perhaps?
Arduino’s, power supplies and programming cables are often bundled. Calling out the individual components is misleading.
Besides, once you have made more than one Arduino project, you’ll likely have extra programming cables. There is nothing special about an Arduino programming cable; it is a standard USB-B to microUSB cable.
You’ll need a power supply no matter what. So calling out the need for an “Arduino” PS is disingenuous.
So NO, I am not exaggerating at all. What is there about a very little circuit designing effort that promotes so much fear in the hearts of arduino followers?
