• Servo Trigger is a board that allows easy control of RC servo motors such as small robots. The servo trigger of an external switch or logic signal can direct the connected servo motor to move from position A to position B. To a servo trigger, the onboard semi-fixed resistor to adjust the start/stop position and transition time.
• An ATTiny84 microcontroller is d for control and a servo control program is executed. Each onboard servo trigger has three semi-fixed resistors. A sets the position where the servo enters when the switch is open, B sets the position where the servo moves when the switch is closed, and T sets the time it takes to return from A to B. There are two operating modes, which can be switched by the jumper (SJ1) on the back. The default is Bistable mode in which the switch is opened to A and closed to B. If the SJ1 is short-circuited, the switch is set to One shot mode in which AB and AB are repeated each time the switch is pressed.
