WiFi Car

Build or use a WiFi-based RC car and control it directly from the KiwisIoT dashboard. The ESP32 connects to the cloud and receives movement, speed, and accessory commands through the topic dash_177xxxxxxxxxx. The car responds in real time to drive motors, LEDs, and a horn from one interface.

How It Works

  1. Create an account if you are a new user, or sign in if you already have an account.
  2. Create a new panel.
  3. Add widgets to the panel.
  4. Save the panel after adding widgets.
  5. Connect your hardware devices with the respective dashboard topic ID; values will be transmitted and displayed in the widgets.

What you need

ESP32 boardESP32 DevKit or similar with WiFi.
Motor driverL298N or other H-bridge for DC motors.
Connectivity libraryPubSubClient or ESP-IDF cloud client.
Chassis & powerWheels, motors, battery, and wiring.

Before You Start

Flash your ESP32 with firmware that subscribes to dash_177xxxxxxxxxx and maps incoming commands to GPIO pins and PWM outputs.

Make sure the server address and credentials in your firmware match your KiwisIoT configuration.

Open the remote control panel to send live commands and verify operation. For wiring details and code examples, refer to the documentation or contact support.

Tips

  • ★ Start with a simple payload format (e.g. direction + speed) and add power/lights/horn later.
  • ★ Use the Lock switch on the remote when you're not driving to avoid accidental commands.
  • ★ Keep the battery charged; low voltage can cause the ESP32 to reset mid-drive.
