6.2 Components Required
1. Node MCU:- NodeMCU is an open-source firmware and development kit that helps you to prototype or build IoT products. It includes firmware that runs on the ESP8266 Wi-Fi SoC and hardware which is based on the ESP-12 module. The firmware uses the Lua scripting language. It is based on the eLua project and built on the Espressif Non-OS SDK for ESP8266.
2. IR sensor :-
IR stands for Infrared sensor,is a electronic device which detects and measures the infrared radiation around the surrounding. IR sensor is used to detect any object or device in it’s range.IR sensor emits infrared rays from the IR transmitter led and if any object is in the range of then the rays are reflected back from the object and receive by the IR receiver led.IR sensor have three pins:
- VCC
- GND
- OUT
3. Jumper Wires :- Jumper are the connecting wires with the connector at each end used to connect different components on breadboard or any other testing boards.
4. Servo Motor:
A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. Servomotors are used in applications such as robotics, CNC machinery or automated manufacturing.Servo Motor have three pins:
- VCC
- GND
- Signal (PWM)
