IoT Based Mood Lamp (RGB Lamp) Controller Program


Testing of Circuit

  1. Turn on circuit with 12V 1Amp Power supply
  2. Take your mobile and disconnect WiFi or Data Connections.
  3. Turn on WiFi and Look for WiFi network named as “iot-circuit” and connect. password not required.
  4. This WiFi Network is created by your IoT Mood Lamp Controller project.
  5. Open Web browser and Enter IP: Make sure your data connection is disabled.
  6. You will find below screen and start operating it. (Software is stored inside ESP8266)

    Software Screen
  7. Click on Color Selector Button and then press SET to Set selected color on mood lamp i.e. RGB LED Strip.
  8. If you want to access it in your WiFi network and want to connect it to your wifi network.
  9. Click on settings. You will see these options.wifi setting
  10. Enter your network SSID and Password and Save it. This setting is saved in internal EEPROM. No need to set it again on power on reset.
  11. Reset the circuit with Power on off cycle.
  12. Open web browser in your laptop and enter http://iot.local . If device is connected to your WiFi hotspot then you can see mood lamp controller screens. Note down the IP is shown in below of this screen. Note: Android phone does not support local domain names. Use IP address to open the temperature controller panel. Api Key is not used in program.
