Two Servo Triggers: Sharing a switch?

Other Miscellaneous
1

Let’s say I have two SparkFun Servo Triggers sharing the same power source, each to their own servo. Then to both units, I wire-in the same single switch. Does that work to trigger both? Do nothing? Release smoke? (My two triggers and pedal switch are in the mail.)

Hi Derek,

You should have no issues using a single button/switch to trigger both Servo Triggers. Since you’re just pulling the BTN line low with the switch, it should work just fine. That BTN is just an I/O pin on the ATTiny microcontroller and is not directly connected to your servos or the power circuit.

Let us know if you have any other questions about the Servo Trigger and we would be happy to help.
