I am pretty new to Arduinos and programming. I am copying and pasting and hacking my through, trying to learn in the process.
I have an idea for a garage parking sensor. I want to use the HC-SR04 sensor and when it "see's" something at about 2 feet, turn on a stop light. I have a switch on my garage door and I plan on powering this unit up only when the garage door is open. Originally I wanted to use the arduino nano because it is so small.
I have a bread boarded sample working on my desk. I thought about adding a 10k ohm pot to an analog input and use it to control the distance I am looking for.
I also have several arduino uno's and I have a Ethernet shield. Now I am thinking about using the uno and hooking it up to my home network. But I have several questions.
If I hook this up to my home network, would I be able to see it on my network and program it through the network as if it were hooked up via the usb port? I assume I would have to leave it on all time, not power it up when the door is open. Instead of the 10k pot I would like to change the sensing distance from my pc. Is this do-able? Going further, it would be nice if I could get it to send a message or something when the sensor hits.
Thanks in advance and Merry Christmas.
