Product description: Simple servo controller - SparkFun Servo Trigger
A simple controller allowing the servo to move from position A to B after changing the state on the IN input pin. The output and target position and the servo transition time can be adjusted with potentiometers. The system is controlled by an ATTiny84 microcontroller with software installed. The module operates at 5 V. The leads are holes for soldering goldpin connectors - 2.54 mm pitch (not included, to be purchased separately).
Connection
| Pin | Description |
|---|---|
| VCC | Supply voltage 5 V. |
| GND | Ground. |
| IN |
Digital input signal, shorting to ground causes the servo to move from position A to B. A switch can be used in this circuit. For example tact-switch connected to IN and GND pins. |
|
SIG VCC GND |
Connector for servo, SIG is a control signal, VCC - power supply, GND - ground. |
SparkFun Servo Trigger Specifications
- Operating voltage: 5 V (max 5.5 V)
- Current consumption: approx. 5 mA
