I have a car which I made but recently it's Bluetooth HC 05 stopped  working and now I dont know how to quite up my kid without spending too much money,please tell me if we can make a remote(wireless because wired is not much fun) for rc car under $1.50 or my wife will tell to just get a new car for him which will make me spend money more than $1.50

You may be able to get it done with such a small budget in parts (I remember some years back buying a complete RC car for about 6 USD so the wireless part can't be more than about 1.5 USD) but with a whining kid around it's going to take you forever. And of course you don't have the advantage of big volume.

Are we getting the full story here ?

If the HC 05 stopped working why dont you just replace it ?

the hc 05 is costly

[wvmarle]

Agreed, they're costly, and way out of your USD 1.5 budget. I paid some USD 2.7 each for mine, a few years ago.

The HC05s have gone up significantly over the years, they can be as much as $4 these days.

Although I guess if you buy maybe 100,000 of them you might get the price each under the $1.50 budget.
