This is a DIY project guide for building an Arduino-based robotic hot glue gun. The guide includes a list of required components, including: * Arduino UNO * LCD display * Rotary encoder * Stepper motor driver expansion board * LV8729 stepper driver * LM2596 DC-DC adjustable buck converter * 12V power supply * Barrel plug connector (optional) * Power supply jack socket female panel mount (optional) The guide also includes a list of required hardware components, including: * Printed parts (e.g., servo bracket, drive roller, copper tape spool holder, OLFA scissors holder) * Bearings (624zz) * Screws and nuts (M4x10, M4 nut with top half filed down, M3x22, M3x16, M3x8) * Jumper wires * Rubberband The guide provides step-by-step instructions for assembling the robotic hot glue gun, including: 1. Printing all of the STL files except for the servo bracket. 2. Screwing the stepper motor bracket to the board and pushing on the drive roller. 3. Installing the M4 screw and washer into the 624zz bearing and screwing them into the bottom stepper arm with the M4 nut securing. 4. Grind down the top of the nut so it doesn't interfere with the stepper motor. 5. Installing the bottom arm with the M3x16 screw onto the stepper. 6. Screwing in the copper tape spool holder so the tape feeds in straight. 7. Installing the OLFA scissors with the printed parts so the scissors are close to the copper tape exit. 8. Installing the servo next to the scissors and using a paperclip to connect the servo horn to the top scissor arm. 9. Connecting the wires and installing the 12V barrel plug connector and the screen and rotary encoder holder. The guide also mentions flashing the Arduino sketch and testing it out. Overall, this is a complex project that requires careful planning and execution. The guide provides detailed instructions for assembling the robotic hot glue gun, but users should be prepared to spend time and effort on each step of the process.
