This piece of code positionned the motor at -179 after it drives back at -180.When the motor drives back, it starts from -179° (do a full turn) and stops at -180 (when hitting the switch button). But -180 is not correct because its -179° the real value of the ISS. So just moving the motor 1° back to be as precise i can be
View Instructable »I wish i knew the reason, but i dont know why. Did you try to understand whats the difference between the 1st and 2nd turn? Have you extracted the value of "Angle_Longitude" in serial print to see if Angle_Longitude = -179?Because the only condition to do a drive back its to Angle_Longitude = -179, if not, no drive back

Hello, i don't use Raspberry Pi, so I can't tell. But if you can control Stepper Motor, and servo motor, you can adapt the code for this µC

did you try with another GPIO? D4 for instance is not use on my project
yes, -180° or +180°
Hi, on the picture, the Servo is connected directly to the 5V (as the Wemos, the Stepper, the neopixels), They are all connected in parallel, i used a 3A to provide enough current for all components

Okay, so D3 isn't the better GPIO to use on your Wemos. Have you try to use another GPIO free (D4 for instance).Modify in the code :/*--------Déclaration Butée--------*/const int Switch_Buttee = D4;// (use D4 instead of D3)
Hi,you connect the limit swicth to D3 and GND. Connect the limit switch in a manner that the circuit is opened/broke when we push on the switch (so the circuit is closed when nothing push on it). This is to avoid any wrong lecture due to a voltage peak.Thus, when the limit switch is not pushed, D3 = GND
The Servo motor is powered directly by 5V of the power supply, not the 5V from the Wemos

Hello,The Stepper Driver Board is hidden in the copper tube (32mm of diameter) :)I used 0.5 mm diameter cable to connect the neopixels
Hello,yes I've printed these parts by myself. I'm sorry but I will not do that, but you can easily find someone who can print these parts around you on Prusa Printer community website : https://www.prusaprinters.org/have a good day

Hey, I think the laser i purchased is not really a 100 mW as in the spec, but i dont have any tool to measured the power beam. Before I set the laser, i performed a test : I let the laser beam on the same spot on the globe over 30 min and no damage ont the plastic.I think you have to test to know if the laser beam is powerful enough to be visible trough the globe.
Hello, thank you :)As I use Longitude and Latitude coordinates, there is not impact on the code depending the size of the globe. BUT, the mechanical assembly should be adjusted, you must center the rotation of the laser in the center of the globe
Hello, thank you :)I dont really know Rocinante, is it a space ship from Comics? If so, the lamp can't track a non real thing ;)

I should do a time lapse video of the laser following the ISS, for sure.If you are looking in the 3rd video (the vertical one), the laser move a tiny bit :) But yeah, a time lapse should be better to look at.

- antoine.seveau commented on antoine.seveau's instructable ISS Tracking Lamp
You can do it ;)
View Instructable »What you see in the 1st video is the calibration (each time you connect the lamp to the Wifi). Then you have a smooth tracking (it moves every 30 seconds to the new positions of the ISS)I purchased a 18cm diameterI cant wait to see your work :)

Thank you,according to amazon this is a 100mw laser.Here the link to this laser:https://www.amazon.fr/dp/B0772RKT9T/ref=pe_3044141_185740131_TE_item

Hello, sorry for not mentioning the Stepper Library i've used for this project. I've worked with an arduino library for 28BYJ48 Stepper motor and ULN2003 driver, and there is the link :https://github.com/rydepier/Arduino-and-ULN2003-Stepper-Motor-DriverThose cheap steppers will not drive properly with the standard Arduino stepper motor library.Let me know if it works better, and i will change my instructable if so.Thanks
- antoine.seveau commented on antoine.seveau's instructable ISS Tracking Lamp
Thank you :)
Well this Arduino code is written to track the ISS, but if you can get the latitude and longitude of something else, you can track it (car, aircraft, boat, submarine, ...) The laser beam can reach nearly every points of the globe
