Need a tiny servo for a tiny task? Try the FS90 Micro Plastic Gear Servo! This servo is great for scanning type sensors, tiny robots, and more! Each servo comes with a variety of horns. The metal gears give this servo even more power and durability!
These servos use a standard PWM signal to control them. The Arduino does a great job of controlling PWM Servos, making it ideal for a variety of robotic projects. But sometimes powering these servos can be problematic. Powering servos from the Arduino's 5v regulator leads to underpowered servos, limited by both voltage and current. With other sensor systems, connecting a servo to an external power supply requires multiple cables or boards, defeating the purpose of a sensor shield. The RobotGeek Sensor Shield solves this problem with 2 jumpers to control the output voltage of the 6 PWM channels on the Arduino. Just move the jumper from '5V' to 'Vin' ans your servo will start to draw power from your Arduino's input voltage supply. Just plug in a 6v power supply into your Arduino, and you'll be able to power and control 6 RobotGeek Servos with no problem!
