Wireless communication is awesome! Right? Only problem is that there are many different methods and techniques which all use different frequencies and sometimes require extra hardware. But if you do not want to spend extra money on hardware, then the ESP microcontroller boards offer WiFi and Bluetooth. Those only come with a "short" range though. So in this video I will test ESP-NOW which is a wireless communication method that can be used with the ESP boards. It gets rid of many disadvantages while not needing extra hardware. So let's see what it can do and ultimately push it to the limit by building a crude Walkie-Talkie. Let's get started!
