It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. Arduino UNO R3 The classic version: Arduino/Genuino Uno is a microcontroller board based on the ATmega328P. The SG90 mini servo with accessories is perfect for R/C helicopter, plane, car, boat and truck use. It is with excellent performance and high torque of 1.5kg cm gives you the freedom to use it for a variety of projects. Servo SG90: The SG90 mini servo is lightweight, It is standard Quality and lightning-fast servo, designed to work with almost all the radio control systems. The length of this pulse is the time it took the signal from first triggering to the return echo.
If there is a signal returning, a high level pulse is sent on the echo pin.
High sensitive module can be used with 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. Ultrasonic HC-SR04 DISTANCE Measuring module: This ultrasonic sensor module can be used for measuring distance, object sensor, motion sensors etc.
