I want to build a smart desktop display for myself which, when its done, should be able to read Data sent by a phone and show it on a lcd display.
I want it to function like paying with your phone. You just have to hold the phone onto the thing and the Text appears on the lcd display. How could i do do this?
What clock?
You will need to implement NFC, or Near Field Communication on the Arduino, and write code to execute the payment protocol. Such code would be complex, and probably would not fit on an Arduino Uno.
Im sorry i meant block. It looks like a block when it’s encased. I shouldn’t have formulated it like this since nobody except me could know that. Sorry
I don’t need it to execute a payment protocol. I just meant I want it to read information, like a sentence, from my phone after I held it onto it.
The simplest way that I can think of would be for the phone to put the data into a BLE Advertising packet and for your device to scan for advertisements and get the data from the one with a signal strength that shows it's very close.
Most payments do it with NFC (Near-Field Communication), if I remember correctly, but I don't know how much support there is in arduino for NFC devices.
Thanks. I will try this. Do I need a special app for sending the information I want?
Would I need to pair the phone with the device?
You would , presumably need to write an “App” on your phone to off load the data you want ?
You need to research how to do that ( difficult ) .
Then you have the interface to look at , Bluetooth ??? Or whatever ?
And finally the Arduino code.
I would research these things separately .
See what others have done .
Prob 9/10 difficulty …. ,
To read the BLE Advertising data? No. Advertising data is visible without connections.
