An ESP-NOW-based remote controller sends control data wirelessly using the ESP-NOW protocol to the remote-controlled car. ESP-NOW enables fast and efficient communication between ESP32 devices without the need for a Wi-Fi router, network, or pairing. The provided tutorial demonstrates a functional setup where a transmitter sends data to a receiver to define the car’s speed and direction, forming the core communication loop. While the baseline @@ -48,7 +48,7 @@ implementation focuses on movement, additional features like lights, sensors, or modular design gives users the freedom to customize both the appearance and behaviour of their RC car, resulting in endless creative possibilities.
To enable real-time remote operation of the RC car, the system translates joystick inputs into PWM (Pulse Width Modulation) signals that control the DC motors. +
To enable real-time remote operation of the RC car, the system translates joystick x- and y- axis inputs into PWM (Pulse Width Modulation) signals that control the DC motors. These PWM values are stored in a predefined data structure, which is then transmitted wirelessly using ESP-NOW — a low-latency, connectionless communication protocol developed by Espressif. Both the transmitter and receiver modules are based on ESP32-C3 microcontrollers.
On the transmitter side, the joystick’s X and Y coordinates are continuously monitored and converted into PWM parameters. These values are packed into the diff --git a/ESP-IDF_Robot/tutorial/docs/build/html/searchindex.js b/ESP-IDF_Robot/tutorial/docs/build/html/searchindex.js index e6d76aaf1..d4ffd1738 100644 ---

- To enable real-time remote operation of the RC car, the system translates joystick inputs into PWM (Pulse Width Modulation) signals that control the DC motors. + To enable real-time remote operation of the RC car, the system translates joystick x- and y- axis inputs into PWM (Pulse Width Modulation) signals that control the DC motors. These PWM values are stored in a predefined data structure, which is then transmitted wirelessly using ESP-NOW — a low-latency, connectionless communication protocol developed by Espressif. Both the transmitter and receiver modules are based on ESP32-C3 microcontrollers.
