Combo of SG90 Micro digital servo motor with HC-SR04 Ultrasonic distance sensor module

SG90 - This is a small servo motor with hard plastic gear. This small and lightweight servo comes with high output power. Thus, it is ideal for  RC Airplane, Quadcopter, Robotic Arms, etc. It is a digital servo motor that receives and processes PWM signals faster and better. This motor equips with sophisticated internal circuitry. This feature provides good torque, holding power, and faster updates. They are packed within a tight sturdy plastic case which makes them water and dust-resistant. So if your application requires stronger and long-running motors you can go with our new and improved SG90 servo motor. HC-SR04 - This ultrasonic sensor module can be used for measuring distance, object sensors, motion sensors, etc. The high-sensitive module can be used with a microcontroller to integrate with motion circuits to make robotic projects and other distance, position & motion-sensitive products. The module sends eight 40Khz square wave pulses and automatically detects whether it receives the returning signal. If there is a signal returning,  a high-level pulse is sent on the echo pin. The length of this pulse is the time it took the signal from first triggering to the return echo.
