Hi, i googled but all the results require a bit of knowledge to understand, i basically know nothing about wireless communications, there is NRF24L01 etc it just confuses me, i got a super cheap one (radio communication) but it just gives noise! i want to be able to communicate with a range around 10m-20m and another one for a range less than a meter! what are my cheap options?! my goal is to communicate 2 arduinos, i might just use one of the arduinos as a dongle to PC or an Android phone! (Bluetooth has a small range) also, i don't want a high latency for 10m-20m one, its going to be an RC car!
and for a 2-way communication, i basically need two of same of a module?
