Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5027173. Today we explore the use of an ESP32-CAM (ESP32 with Camera) as a directional motion sensor. While motion sensing with an ESP32 has been available for some time, I take it to the next level using it in an animatronic Halloween project. The project uses only an ESP32-CAM as the entire motion detector and the microcontroller driving the stepper motors. The entire project is open source allowing you to use this in robotics or other projects where you need a cheap and easy motion sensor. This project is limited only by the visual range where many PIR and Ultrasonic sensors have a limited range. This works great for projects where you want to detect a cold object (not a living body) or objects far away. The base code uses a 10 degree range for its stepper movement but you can alter the code and the way the project works to fit your specific needs. I also cover how you can purchase an inexpensive IR Floodlight to enable the use of this at night or in low light situations. This worked great as a Halloween animatronic project where a spooky inflatable eye follows you around the yard. https://www.youtube.com/watch?v=NIbiG6at01g Used in this project: eSun Black PLA - https://www.amazon.com/eSUN-1-75mm-Printer-Filament-2-2lbs/dp/B01EKEMDA6?cv_ct_cx=esun+black+pla&dchild=1&keywords=esun+black+pla&pd_rd_i=B01EKEMDA6&pd_rd_r=78dd6800-c6ac-4e89-9346-b2d617903929&pd_rd_w=f4jhQ&pd_rd_wg=exdHn&pf_rd_p=c0fa563a-b0ba-455a-bd65-7b14bea6288c&pf_rd_r=Z2TRXHGP1B1892GA96QG&psc=1&qid=1634843829&sr=1-1-f0029781-b79b-4b60-9cb0-eeda4dea34d6&linkCode=sl1&tag=rwmech-20&linkId=b6692b8dba9b24f305952f9ac2112913&language=en_US&ref_=as_li_ss_tl ESP32-CAM - https://www.amazon.com/eSUN-1-75mm-Printer-Filament-2-2lbs/dp/B01EKEMDA6?cv_ct_cx=esun+black+pla&dchild=1&keywords=esun+black+pla&pd_rd_i=B01EKEMDA6&pd_rd_r=78dd6800-c6ac-4e89-9346-b2d617903929&pd_rd_w=f4jhQ&pd_rd_wg=exdHn&pf_rd_p=c0fa563a-b0ba-455a-bd65-7b14bea6288c&pf_rd_r=Z2TRXHGP1B1892GA96QG&psc=1&qid=1634843829&sr=1-1-f0029781-b79b-4b60-9cb0-eeda4dea34d6&linkCode=sl1&tag=rwmech-20&linkId=b6692b8dba9b24f305952f9ac2112913&language=en_US&ref_=as_li_ss_tl Signal Cable (Dupont) - https://shop.layerfused.com/collections/electronics/products/2m-premium-3d-printer-cable-female-dupont-to-female-dupont-6-pin-24awg Stepper Motors - https://www.amazon.com/eSUN-1-75mm-Printer-Filament-2-2lbs/dp/B01EKEMDA6?cv_ct_cx=esun+black+pla&dchild=1&keywords=esun+black+pla&pd_rd_i=B01EKEMDA6&pd_rd_r=78dd6800-c6ac-4e89-9346-b2d617903929&pd_rd_w=f4jhQ&pd_rd_wg=exdHn&pf_rd_p=c0fa563a-b0ba-455a-bd65-7b14bea6288c&pf_rd_r=Z2TRXHGP1B1892GA96QG&psc=1&qid=1634843829&sr=1-1-f0029781-b79b-4b60-9cb0-eeda4dea34d6&linkCode=sl1&tag=rwmech-20&linkId=b6692b8dba9b24f305952f9ac2112913&language=en_US&ref_=as_li_ss_tl Dupont Terminal Blocks - https://www.amazon.com/eSUN-1-75mm-Printer-Filament-2-2lbs/dp/B01EKEMDA6?cv_ct_cx=esun+black+pla&dchild=1&keywords=esun+black+pla&pd_rd_i=B01EKEMDA6&pd_rd_r=78dd6800-c6ac-4e89-9346-b2d617903929&pd_rd_w=f4jhQ&pd_rd_wg=exdHn&pf_rd_p=c0fa563a-b0ba-455a-bd65-7b14bea6288c&pf_rd_r=Z2TRXHGP1B1892GA96QG&psc=1&qid=1634843829&sr=1-1-f0029781-b79b-4b60-9cb0-eeda4dea34d6&linkCode=sl1&tag=rwmech-20&linkId=b6692b8dba9b24f305952f9ac2112913&language=en_US&ref_=as_li_ss_tl USB Power Interface - https://www.amazon.com/eSUN-1-75mm-Printer-Filament-2-2lbs/dp/B01EKEMDA6?cv_ct_cx=esun+black+pla&dchild=1&keywords=esun+black+pla&pd_rd_i=B01EKEMDA6&pd_rd_r=78dd6800-c6ac-4e89-9346-b2d617903929&pd_rd_w=f4jhQ&pd_rd_wg=exdHn&pf_rd_p=c0fa563a-b0ba-455a-bd65-7b14bea6288c&pf_rd_r=Z2TRXHGP1B1892GA96QG&psc=1&qid=1634843829&sr=1-1-f0029781-b79b-4b60-9cb0-eeda4dea34d6&linkCode=sl1&tag=rwmech-20&linkId=b6692b8dba9b24f305952f9ac2112913&language=en_US&ref_=as_li_ss_tl Micro USB Cables - https://www.amazon.com/eSUN-1-75mm-Printer-Filament-2-2lbs/dp/B01EKEMDA6?cv_ct_cx=esun+black+pla&dchild=1&keywords=esun+black+pla&pd_rd_i=B01EKEMDA6&pd_rd_r=78dd6800-c6ac-4e89-9346-b2d617903929&pd_rd_w=f4jhQ&pd_rd_wg=exdHn&pf_rd_p=c0fa563a-b0ba-455a-bd65-7b14bea6288c&pf_rd_r=Z2TRXHGP1B1892GA96QG&psc=1&qid=1634843829&sr=1-1-f0029781-b79b-4b60-9cb0-eeda4dea34d6&linkCode=sl1&tag=rwmech-20&linkId=b6692b8dba9b24f305952f9ac2112913&language=en_US&ref_=as_li_ss_tl
