Description

Highlights

Moves a standard Hobby/RC servo between 2 positions continuously for as long as a switch is pressed.
Trigger output signals at ends of motion can be used to trigger other Servo Cyclers / Relays in a coordinated manner.
No programming or coding of any kind!
The two positions to cycle between are set by two potentiometers.
The speed of motion between the two positions is set by a potentiometer.
Additional two potentiometers set the trigger duration / wait time at the ends of motion.
Works with 90 degree or 180 degree servos
Jumper options allow the adjustment ranges of the potentiometers to be changed.
Works on standard 5V and also up to 30V for higher voltage servos.
Motion will always complete the full cycle and come back to Position1 when the switch is released.
See datasheet for details

Potentiometers/Jumper Settings

Potentiometer ranges can be adjusted by the jumpers for more resolution of adjustment.
Potentiometer1 (leftmost) sets Wait Time at position1 0->10.5 Seconds /0->168 Seconds depending on jumper under it
Potentiometer2 Sets Position1 0->90 Degrees / 0->180 Degrees depending on jumper8
Potentiometer3 Sets Speed of motion . Range adjustable by jumper 3&4 under it.
Potentiometer4 Sets Position2 0->90 Degrees / 0->180 Degrees depending on Jumper8
Potentiometer5 (rightmost) Sets Wait Time at position2 0->10.5 Seconds /0->168 Seconds Depending un jumper under it

Bridge (short) these jumpers on the back of the board to change operational modes and the range of adjustment set by the pots.
JP1 : Sets the width of the trigger pulse sent out when at position 2 . 100mS (unbridged) / For full duration of wait (bridged).
JP2: Changes wait time adjustment range at position2 0-10.5 Sec (unbridged) / 0-168 seconds (bridged)
JP3: Changes Max Speed 256 Degree/Sec (unbridged) / 32 Degrees/Sec (bridged)
JP4: Changes Max Speed 256 Degree/Sec (unbridged) / 4 Degrees/Sec (bridged)
JP3&4: Changes Max Speed 256 Degree/Sec (both unbridged) / 2048 Degrees/Sec (both bridged) – (if servo can go that fast.)
JP5: Changes wait time adjustment range at position 1 0-10.5 Sec (unbridged) / 0-168 seconds (bridged)
JP6 : Sets the width of the trigger pulse sent out when at position 1 . 100mS (unbridged) / For full duration of wait (bridged).
JP7 : Makes Triggerout2 Trigger at both ends of motion. TriggerOut2 (unbridged) / TriggerOut2 OR TriggerOut1 (bridged)
JP8 : Sets range of signal 90/180 degrees 1mS->2mS/0.5mS->2.5mS
JP9 : Inverts the Input Trigger Polarity Low Going (unbridged)/ High Going (Bridged) – (RevA14+ Firmware)
JP10 : Inverts the Pos2 Output Trigger Polarity Low Going (unbridged)/ High Going (Bridged) – (RevA14+ Firmware)
JP11 : Inverts the Pos1 Output Trigger Polarity Low Going (unbridged)/ High Going (Bridged) – (RevA14+ Firmware)
Note for JP10 and JP11 Jumper the across 3 Holes towards the edge of the board. From Top(11) and Middle(10) pin to the pin labelled G
Note: When setting positions/90/180 etc, do not rail servo against end stop for any long period as it will burn out the servo.

Specs

Supply voltage: 5V – 30V (Set by your servo voltage).
Dimensions: PCB : 40mm x 18mm (1.56 x 0.70 Inch) / PCB + Connectors : 55mm x 18mm (2.20 x 0.70 Inch)
Part Numbering SVO-CYC-01
Trigger Input can be a switch to ground due to pullup to 5V on the board, but can be driven 0-5V by Arduino etc.
Trigger Output is a 0-5V output

Applications

Suitable for moving a standard RC/Hobby servo motor between two fixed positions.
Use for Product testing, eg repeated pushing of buttons
Moving a mirror
Halloween mechanisms
Use Triggers to Activate Counters for counting cycles
Use Triggers to Activate Solid State Relays To actuate Solenoids or Other Loads – Use JP9 to invert Triggers
Mechanisms needing Back and Forth motion
Tube cutter- use continuous rotation servo to extend tubing, solenoid to cut tubing
Liquid Dispenser- use trigger to actuate dispense pump, and servo to direct flow to intended area.
