EXCLUSIVE - Servo Electronics Guide for Movie Ghost Trap (Patreon)

Last November, I published a new set of movie-style Ghost Trap files. One of the mechanisms I worked out was a servo + gear assembly that allowed for both doors to be opened and closed with a single servo. This makes the door electronics quite efficient (in comparison, these electronics use two servos and an armature).

Additionally, I also employed the use of an NRF model to trigger the open-close action remotely. This allows me to avoid having to run wiring to the trap from a pedal or remote control. I really like these modules - they are easy to program and they have great range in my basic tests.

What you'll need to complete this project (see diagrams below):

• Arduino UNO (main board in trap) 
• Arduino Nano (for remote control) 
• 9G Servo Motor 
• NRF module (x2)
• Jumper cables
• Push buttons
• Power switches
• 10 uF Capacitor x2 (for the NRF module power - you will need to perform basic soldering to connect the Capacitor to the module. Check these instructions out)
• Power source for Arduinos (minimum a 9V battery with connector)
