Topic: Help with choosing device and shield (Read 113 times) previous topic - next topic

Hi,

I've two projects in my mind but I don't have much experience with electronics and no experience with arduino. I ask for guidance about which arduino(s) to get, and respective shields for it(them) in order to make these projects. Also good question are my projects plausible or not.

Project 1: I would like to create a piston like device and it's movement to be governed by a wave equation by arduino.
Project 1.1: following this thought the device position to be able to be defined by a sensor.
(do I need two arduinos or just one to complete the three actions)

Project 2: Bluetooth positioning system. A network of bluetooth slaves and one master that sends signals and this way determines it's position. Do I need arduino hooked up to each bluetooth slave or just one for the whole network, and one for the master bluetooth.

Any help will be appreciated.

Hello and welcome.

If you do not have much experience, you could probably start with the Arduino UNO. I think, you cannot do a mistake with the UNO. Both your projects seem to be realizable with the UNO.

Project 1 can easily be achieved with any Arduino.

I do not understand project 2. Can you elaborate?
If you understand an example, use it.
If you don't understand an example, don't use it.

I honestly believed project 1 would be more difficult to understand. :)
Look at project 2 as an indoor GPS system. Instead of satellites you have the network of passive(or active) bluetooth points. And instead of your navigation device you have an arduino with active bluetooth that sends signals to the network and depending on the strength of the signal to each at least 3 bluetooth devices you can via triangulation determine the position.

I just wonder whether I need each bluetooth device from the network to be active, hence having arduino hooked up to each and every one of them. It has to be mentioned as well that the network devices must be sync-ed time-wise.

The reason I was asking is that I read several articles about choosing Arduino vs Raspberry PI, and all of them say Raspberry PI is when you're multi tasking, and Arduino is for repeating single tasks.

Do I need a Raspberry PI and/or Arduino to do my projects as they are not just one action.

in Project 1 I have a device controlling the piston, and it also has to read the data from the sensor and change the wave equation, and the piston will be affected by the data coming from the sensor.
