We will use the common Arduino programming software to program this device. This device is not an Arduino product so other people have created modifications to the Arduino programming software so it works with this device. Setup consists of the following.
1. Download and install an older version of the Arduino programming software.
2. Add modifications to the software for this device.
3. Add libraries to the programming software for other devices like the temperature sensor.
4. Connect device to PC USB port and serially upload Basic_OTA programming including adding your network SSID and password changes.
5. Unplug device USB from PC and plug into USB power supply. It will reboot and connect to your network.
6. Look under ports in the programming software and you should see a new IP address for the device listed. Click on it to use as a wireless programming port.
7. Upload ESP Temperature Only program.
8. Plug in the temperature sensor as shown in the pic.
9. Put device IP address in a web browser and you should be able to turn on and off the Blue LED and display the temperature as shown in the YouTube video.
10. To ensure the IP address of the device doesn't change go to your router settings page and reserve the IP number. It should be beside a new user called ESP. Change the username if you want.
11. Plug in remaining hardware as shown in the pics and tailor example program to your application.
