Controlling Plastic Injection Machine Nozzle Movement with a Digital Laser Ruler

In this video, I'll demonstrate how to create a controller for the movement of the nozzle on a plastic injection machine using a digital laser ruler. In the previous video, "DIY Digital Laser Ruler Tutorial with VL53L0X GY-53, SSD1306, and Wemos D1 Mini | Arduino Project," I showed how to build a digital laser ruler. In this video, I'll use that same digital laser ruler, along with a 4-digit display module, a "28BYJ48" model stepper motor, a "ULN2003" driver, and a "Wemos D1 Mini" Arduino board, to simulate the movement mechanism and control the movement of the plastic injection machine's nozzle.
