Project Description
Develop an ESP32-based wireless communication system comprising one transmitter (sender) unit and five receiver units. The sender will include a single push-button input. When the button is pressed, all receivers must activate a vibration motor simultaneously. The system should support real-time duration mapping: if the button is pressed and held for a specific duration (e.g., 3 seconds or 5 seconds), the receivers must vibrate continuously for the exact same duration, with minimal latency.
Communication can be implemented using ESP-NOW or a low-power wireless protocol to ensure fast and reliable synchronization. Each receiver should be individually powered by a compact rechargeable battery and designed for minimal size and low power consumption. Include efficient power management (sleep modes when idle) and stable vibration driver circuitry. The overall system should be portable, responsive, and robust for short-range wireless operation.
