Remote control is a wonder of the age, we press a button, and something happens as if by magic. But what happens if there is no remote control, and instead a real physical button must be pressed?

At the user end thereβs a button in a printed enclosure thatβs definitely not a knock-off of a well-known franchise from a notoriously litigious console company.
This is all good, but the interest for other projects lies in how it works. Itβs using a pair of ESP32 microcontrollers, and instead of connecting to an existing WiFi network itβs using ESP-NOW for simplicity and low latency. This is a good application for the protocol, but as weβve seen,Β itβs useful for a lot more than just button pressing.
