Motion sensor and arduino

Development Boards Arduino
1

Hello,

I am new to electronics. Sorry for the easy questions. Don’t think this will be a big deal but I would like to be able to, using a motion sensor or range finder, randomly activate one of three led’s when the sensor is triggered. Which arduino board would be sufficient for that and would the code be very difficult? For the motion or range finder, would like something to have a range of 2 to 10 feet. Any recommendations on which product would work for that?

Any help would be greatly appreciated.

Thanks.

Start w/the sensor. A PIR might work but they aren’t “precise”, in either range or field of view (FOV).

Other sensors might be more selective.

Can you be more specific about your sensor requirements ? Or the details of how it’ll be used ?

A basic Arduino, Uno or similar, would be all you need. Perhaps even an Adafruit Trinket would be sufficient.

Coding would be on the easy end of the scale.

Thank you very much for your response. Trying to see if I can make something to help train reactions and reflexes. By having to respond to one of the three led’s when the sensor is triggered. So will need to look at one of the more precise sensors because I would like to be fairly precise at an cost effective price.

I am sure the information is out here somewhere, and I can try to dig into it, but another couple of questions if you don’t mind. What program and process do you have to use to load the code on to the arduino? Would one of the ultrasonic sensors here be fairly straightforward to connect to the arduino?

Thanks.

Most of the sonars output an analog voltage so connection and code is pretty easy.

Thanks again. I will start reading
