Build two-circuit Arduino prototype

Community Jobs and Paid Consultancy

I'd like to build a two-circuit prototype comprising of Circuit A and Circuit B with the properties listed below. Does Arduino have circuits that will support the functionality described below? If yes, I'd appreciate any guidance that can be provided. I'm also open to working with a consultant who can speed up delivery of the prototype.

Circuit A
• Circuit A is a WiFi enabled circuit that is able to push notifications to the internet via email, sms, or trigger notification APIs
• Circuit A is responsible for keeping track of its proximity to Circuit B. Whenever Circuit B is more than 10 feet away from Circuit B, it triggers a notification (email, sms, etc) to inform the user that Circuit B is drifting away from Circuit A.
• Circuit A is battery powered

Circuit B
• Circuit B stays in sync with Circuit A. Whenever Circuit B is more than 10 feet away from Circuit A, Circuit A is notified.
• Circuit B is battery powered

Somehow you do not describe what you want to be done.

Arduino doesn't really "have circuits". But even if I interpret the question as "is there something Arduino related to do the following", the answer is probably no.

There is really not enough information to propose possible solutions. e.g. what is the environment- outdoors, indoors, underwater, on land, in the air?. Are there other objects in the vicinity, and what are they?

What is the battery? 12V car battery or 1.5V coin cell? What is the expected operating time?

How large is the enclosure for the circuits? Do they have line of sight?

Does circuit B needs to be coded to A?

I'll assume the comms between A and B needs to be wireless, otherwise a 10 foot wire with a detachable connector would suffice.

App-based with GPS:

Seems unlikely that a standard GPS system would be much good for detecting, accuratly, if two devices just breach a 10ft distance limit.

Knowing the required accuracy of this 10ft limit would be essential.

You'd need e.g. UWB radios on both sides, so they can measure the distance between them. This can achieve centimeter-level accuracy.

The rest is rather trivial, unless there are many hidden requirements.

Hi bobcousins,

I agree with you. I’ll add more details below

  1. Both circuits will be ran indoors. There might be drywall between them. Both circuits will predominantly remain within the 10 feet range of each other with nothing between them

  2. Both circuits will be powered with regular alkaline batteries

To confirm, are you suggesting that the prototype cannot be built with Arduino components?

Hi wvmarle,

Thanks for your suggestion. Can both circuits be built from Arduino components? Or do you think the prototype will require bespoke components?

Hi srnet,

The 10 foot requirement is flexible. To be transparent both circuits will be relatively close to each other 99% of the time. They’ll go out the 10ft range 1-2% of the time. Centimeter grade accuracy is not necessary

Do you want to solve a problem or do you want to use arduino?

11

Sigh .........

Have fun.

I don't know what an "arduino component" is to you.

You will need some kind of UWB radio on both sides. And no, I don't have specific suggestions on parts here.

You need a way to communicate with those UWB devices; an Arduino almost certainly can do this.

Then you need some components that can produce the light and sound signals you want to get, which in turn can be controlled by an Arduino.

13

You can buy DWM1000 UWB modules from Mouser, etc for $18/ea and solder wires directly to them or make/buy a more breadboard friendly carrier for them. They will communicate with a microcontroller over SPI. There are libraries available to use with them.

Got it. Thank you

15

Thanks Emilyjane. I appreciate the pointers. I’ll investigate the option

Hello zwieblum,

Sorry. I missed your message. I want to solve the problem, regardless of whether the solution involves Arduino or not.
