Hello very good project, Could we add a buzzer or an alarm??????
@HannahMakes
4 жыл бұрын
Absolutely! If you attach a buzzer between microbit's 3v pin and, say, pin p0, then you can add a "set pin p0 to 1" block in the first part of your "if" block, and a "set pin p0 to 0" in the "else" part to trigger the buzzer together with the cross on the screen 👍

Great question! There's no theoretical limit on the number of microbits you could use this on, but in practice, with large numbers of devices in a situation with other radio interference, I don't know how well it would work. Best to have a backup option!

Awesome. I was looking for this and it seems virtually no one has used the micro bit for this purpose. Question: Since the micro bit is continuously transmitting an RF signal, how much does that affect battery life? For example, could it transmit for about 8 hours (a typical work day) on one set of batteries do you think? Also, have you tried using Bluetooth to detect phones near you (not sure if this is even possible with the micro bit)?
@HannahMakes
4 жыл бұрын
Thanks! I would definitely expect that the battery would hold out for a day - I use my microbits for projects and videos and I've changed the batteries once so far! Switching off the radio function would make the battery last even longer though. As for detecting phones, I'm not an expert in Bluetooth, but the blocks available in the MakeCode editor all rely on pairing the microbit with another device - which would mean the other device would have to consent to the pairing. Plus, from the microbit documentation: "A maximum of 4 devices may be paired with a micro:bit simultaneously (note though that only one paired device may connect to the micro:bit at a time)." So I don't think it would be that viable as an alternative if you were just using MakeCode. However, not knowing so much about bluetooth, I couldn't say categorically whether you could write some code by other means that would do something like that. Interesting thought though!

Hello. A simple and great. Can anyone say, would it give upto 360° or atleast 180°? And Shall we attach any sensors along with the radio communication code? Please
@HannahMakes
3 жыл бұрын
Hi! I'm not sure what you mean by "up to 360º" - the radio signal goes in all directions, so it shouldn't matter which microbit is on the left and which is on the right, for example. And you don't need any extra sensors - the microbits are figuring out the approximate distance based only on the radio signal they're sending each other.

@HannahMakes
4 жыл бұрын
I couldn't guess off the top of my head, but I can tell you a fun way to check :) Write a couple of lines of code to make one microbit transmit data to another. Next, write a couple of lines of code for the other microbit to make it display on screen the signal strength of the messages it receives. (Use a "received packet signal strength" block at the bottom of the radio menu.) Then, place the two microbits 1.5m apart. The screen of the second microbit will display the signal strength at that distance :) Hope this helps!

I don't know exactly, but you can find out with just a couple of lines of code! Here's some instructions I left for another commenter: Write a program that make one microbit transmit some data to another (the data can be anything you like, maybe just a number). Next, write a some code for the other microbit to make it display on screen the signal strength of the messages it receives. (Use a "received packet signal strength" block from the radio menu.) Then, place the two microbits 1.5m apart. The screen of the second microbit will display the signal strength at that distance :) Hope this helps!

why not use a ultrasonic sensor
@HannahMakes
4 жыл бұрын
Because that's more complicated ;) I wanted this project to be as simple as possible. Ultrasonic sensors would be really interesting, but they'd also tell you when you were 2 metres away from furniture rather than people, which could get annoying. The two microbits are only listening out for each other :)
