i would be happy if you would give me tips on my current arduino project.
i want to let ten arduinos talk to each other (Wireless, tx / rx)
It's supposed to be simple.
Each Arduino sends (e.g. every 10 minutes) its uptime to all others.
Each arduino calculates in which order it stands with regard to uptime. (If Arduino X was started three minutes ago and Arduino Y 10 minutes ago. Arduino Y is first and Arduino X is second....).
An LED lights up on the Arduino with the longest uptime.
Battery operation with the longest possible operating time.
Each Arduino should be as small as possible (e.g. Arduino Nano).
- which communication modules (433mhz or bluetooth or WLAN...) would you recommend to me?
- which battery supply would you recommend?
Many thanks in advance
