EDIT: 4/8/2020 Added Schematic Added Pictures EDIT: 4/7/2020 Added code for relays that are activated with a LOW signal Ardunio_Nano_Stepper_28BYJ-48_Potentiometer_Low_Activated_Relay.zip Edit: 4/6/2020 Moved speed pot away from screw hole. Added base without push button and relay mount. 170mm wide Smaller size of Urzas_creations' "Rotating Platform: Arduino meets 3D Printing | Stepper Motor 28BYJ-48 + ULN2003" is used. https://www.thingiverse.com/thing:4094599/comments Added Screws to hold top on Pot Speed Control using Robojax excellent code "Control Speed of Stepper Motor 28BYJ-48 with potentiometer - Robojax" https://robojax.com/learn/arduino/?vid=robojax_stepper_28BYJ-48_pot_speed Soon as I get the schematic done, I will post here. At power on, an output is turned on (Mini 1/8 Audio Aux mount). Optional: It turns my UV light on and off. Turn Table starts and runs 15 minutes (changeable in the code). After 15 minutes, table stops, Output turns off to Mini 1/8 Audio Aux mount. A buzzer sounds for 60 seconds (changeable in the code). Then program is ended. Optional for safety, you can wire and use a push button to activate a relay that self-latches to hold power to run everything. After buzzer ends, it will release the relay. This is NOT in the Code Yet. Parts Used: This list is just a list. I get nothing from these links; Search for better deals.
