Driverbot

A car that can be remote-controlled via a web interface using MQTT.

Setup

cd aedes-broker-mqtt
npm install

cd aedes-broker-mqtt
node broker.js

Open index.html in your preferred browser.

You control the car using W, A, S & D.

To configure the application to work for your needs you need to change the following files:

In index.html change the host to the IP address of the broker.
- If you want to change MQTT port: In broker.js change the port to the port you want to use. And also change port to the corresponding port in index.html
In main.cpp change WiFi SSID and password to your needs. Also, change the broker IP and port in the PubSubClient setup.

Issue 1: The car doesn't respond to control commands.
- Solution: It can depend on many things. Make sure the car is connected to the MQTT broker and the MQTT messages are being received correctly. Check the broker logs and verify the connection settings in index.html. Also, check the Config section in main.cpp.
Issue 2: The car moves in the wrong direction when using the controls.
- Solution: Change the reversedMotor variable in main.cpp to true or false depending on your needs. Alternatively just change the wiring of the motor.
