thingiverse

A Little Robo-Buddy Built From Arduino Nano, Adafruit 8x8 LED Matrix, and 3 Cheap SG90 Servos. This project is a checkpoint and concept test for a longer-running project that works off the same ideas. If everything goes to plan, I should be able to show off my work for that one on Thingiverse as well. Materials Used: -Adafruit 8x8 1.2" LED Matrix -3x SG90 9g Servo Motors (and each one's associated screws [2x sides, 1x top] and servo attachments) -Arduino Nano -Breadboard/Wires/Etc... -4x M4*12 Screws & Nuts -Hatchbox PLA Assembly Instructions: 1. Gather components & print parts. 2. Screw base tripod into something reasonably heavy, like plywood (or you could just tape it down as I did). 3. Place first servo in base. Screw in side screws. 4. Insert servo attachment into the indent of the first arm and screw it in place with the small top screw. 5. Mount second servo on the first arm using a second set of side screws. 6. Repeat step 3 for the third servo. 7. Repeat step 4 for the third servo. 8. Take the last servo attachment and place it into the indent on the 'Eye_Holder_Screw+Servo_Attachment'. 9. Line up the LED_Matrix_Eye_Holder with the part mentioned previously and clamp them together using M4 screws and nuts. 10. Carefully line up connected structures to the third servo, drop the third small screw down the center and carefully screw it into the servo's top. 11. Slide the LED Matrix in place and then attach the 'Eye_Holder_Clip' to secure it in place. 12. Upload the code. 13. (Optional) Plead to the gods that it works Hope this post was of reasonable enough quality to allow someone else to follow this project. Will do my best to be helpful. --Cheers
