Working voltage: DC5V Working current: less than 15mA when at rest, less than 250mA when working Operation mode: infrared remote control Working mode: up to 11 working modes Drive motor: DC 5V 4-phase 5-wire stepper motor 28BYJ48 Product use: DIY screen slider, DIY various small tooling The main function: Multiple working modes are available Mode 1: After a forward rotation, a random delay of 3 to 15 seconds is followed by a reverse rotation, a random delay of 3 to 15 seconds, and an infinite loop. Mode 2: After a forward rotation, a random delay of 10 to is followed by a reverse rotation, a random delay of 10 to , and an infinite loop. Mode 3: After one forward rotation, there be a random delay of 3 to 15 seconds, an infinite loop. Mode 4: After one forward rotation, there be a random delay of 10 to , an infinite loop. Mode 5: After one forward rotation, there be a random delay of 30 to 50 seconds, an infinite loop. Mode 6: After one forward rotation, there be a random delay of 50 to 99 seconds, an infinite loop. mode 7: switch the current mode to forward rotation Mode 8: Switch the current mode to reverse Mode 9: forward rotation all the time, no delay time Mode 10: Numbers 1-9, delay 1-9 seconds after the logo rotates once, infinite loop Mode 11: 5 forward rotations, 1 reverse rotation, random delay of 5-12 seconds, infinite loop Colour:As Shown Material:Plastic Package Contents: 1 * ULN2003 driver board Only the above package content, other products are not included.
