NodeMCU ESP8266 ISS Satellite tracker

NodeMCU ESP8266 Satellite tracker can locate the position of Satellites (currently ISS and HST) and point to it. It uses a stepper motor and a servo for the positioning of the pointer and a simple webserver for calibration and control. It gets the Azimuth and Elevation of the satellite from the n2yo API. Old version used a python server which calculated the Azimuth and Elevation

Once the ESP8266 is booted and connected to your Wifi network, the webserver is started. You have to go to its IP adress in a web browser and calibrate it. You do this by pressing the buttons on the website which move the stepper motor until the pointer points north(You can use your phone as a Compass). This is very important and has to be done as accurate as possible in order to make sure the pointer is accurate. After finishing the calibration the pointer will move and point to the current postion of the ISS. You can verify this by using an app like SpaceStationAR. Now you can switch between satellites by pressing the button and watch the pointer update itself every 10 seconds.

• Define your Wifi Network name and password in the .ino file
• Create an account at n2yo.com and paste your API key into the file
• Also edit the longitude, latitude and elevation according to your current position

Connections:

• Servo: D3
• Stepper: D1/In3, D5/In1, D2/In4, D6/In2
