Hope you are doing great.
Here is my requirement.
I need 2 US quarter coin sized communicators with a button, an LED in the middle and a small speaker to make a beep.
When I push the button on coin1, the LED light and beep should turn on on coin2. The vice-versa is true.
For the communication protocol between two coins, we prefer XBEE because it offers long range. If not, bluetooth works fine too.
This is for kids playing purpose and our maximum budget per unit is $2.
Our maximum time line is 2 weeks and we are ready to bear your time and developmental costs until $200 USD.
Please reach back to us if this is interesting to you.
