Programming an NRF24L01 and Wireless Transceiver Module

Projects Programming

Hi there,

For an engineering projects class we have make a device or product using arduino. Unfortunately, this is a freshman class and nobody knows how to program anything.
My group is making a sort of box that a mother would keep in her purse that would send and receive data from another device attached to a child's wrist (or if it's too big, put in a backpack or something.) The device in the mother's purse would beep if the child got too far away (20 ft or so)
This is meant to sort of replace the child leash.

We did some research and found the NRF24L01 and Wireless Transceiver Module which we thought would work. Do you guys think it would work? How would we start to program it? Are there any example codes that are similar to this that we could learn from?

Sorry to ask so many questions! Thank you so much for reading :slight_smile:

This could sort of work if you don't worry too much about the exact distance. I have a driver for this radio at http://maniacbug.github.com/RF24/ . Basically, you'd send out a ping every so often from the parent to the child, and then if it didn't go through that means the child is out of range. You could eat up your battery pretty quick, though.

This thread probably belongs in the wireless forum, though.
