Creativity think 07 Servo Motor and Ultrasonic Sensor for all micro controlling boards Electronic Components Electronic Hobby Kit

SG90 Servo Motor Servo can rotate approximately 180 degrees (90 in each direction), and works just like the standard kinds but smaller. You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. It comes with a 3 horns (arms) and hardware. HC-SR04 Ultrasonic Sensor The HC-SR04 Ultrasonic Distance Sensor provides very short (2CM) to long-range (4M) detection and ranging. The HC-SR04 sensor provides precise and stable non-contact distance measurements from about 2cm to 4 meters with very high accuracy. It can be easily interfaced to any microcontroller
