Robot project using Mqtt

What you need:

• A WLAN
  I use a simple WiFi Router for this project.
• A Mqtt-broker.
  You can use a minimal broker running on a esp8266 - see Sketch RobotMqttBroker
• Devices, like a esp8266 LOLIN(WEMOS) D1
• To send Mqtt command to the devices, you can use
  • "MQTT-Explorer-0.4.0-beta1.exe" or
  • see https://github.com/aiten/Robot

To run (and compile) all the sketches, please:

• Set Sketchbook location (Arduino Menu: File:Preferences...) to this folder
• Install additional libraries:
  • ArduinoJson (by Benoit Blanchon)
  • EspMQTTClient (by Patrick Lapointe)
  • PicoMQTT (by Michal Lesniewski)
  • PubSubClient (by Nick O'Leary) - included by EspMQTTClient
  • HX711 (by Rob Tillaart) - use for InputForce

Install 8266 Arduino environment

• see e.g. https://arduino-esp8266.readthedocs.io/en/latest/installing.html#
• enter the following text in "Additional board manager URLs:" (Arduino Menu: File:Preferences...): http://arduino.esp8266.com/stable/package_esp8266com_index.json
• Install ESP8266 Boards

Device configuration

• An AP is opened, if the device cannot connect to the specified WLAN.
  The name of the AP is e.g. Robot4WD_xxxxxx (xxxxxx is a unique number)
• To configure the device, please goto page 192.168.4.1
