It is an open-source microcontroller board based on the Microchip ATmega328P microcontroller developed by Arduino.cc.
The board is equipped with sets of digital and analog input / output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits.
The UNO is the most used and documented board of the whole Arduino family
To control the DC motors, use:
Pin 11 for the motor port M1
Pin 3 for the motor port M2
Pin 5 for the motor port M3
Pin 6 for the motor port M4
Pins 4, 7, 8, and 12 may also all be used
To control the Servo motor, use:
Pins 2, 9, and 10 and 13 remain free for use
The L293D is a dedicated module to fit in Arduino UNO R3 Board, and Arduino MEGA. It is a motor driver shield that has full featured Arduino Shield can be used to drive 2 to 6 DC motor and 4 wire Stepper motor and it has 2 set of pins to drive a SERVO.
Arduino’s L293D motor driver shield is compatible with Arduino Mega and UNO. The shield can be fitted on top of the Arduino board. In such cases, six analog pins including pins 2 and 13 remain free for use.
Can use to control Up to 4 bi-directional DC motors with individual 8-bit speed selection, Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
Plastic Gear Motors (also known as 'TT') are an easy and inexpensive way to get your projects moving. It is a TT direct current gearbox motor with a 1:36 gear ratio and comes with 2x200 mm wires with 0.1 male connectors suitable for breadboards. Perfect for connection to a breadboard or terminal blocks.
These Motors can be powered with 6VDC up to 12VDC, they will of course go a little faster at higher voltages.
These are very basic motors, without integrated encoders, speed control or position feedback. Tension in, rotation out. There will be variations from engine to engine, so a separate feedback system is needed if you need precision motion.
Servo motor is a simple DC motor with a position control service. By using a Servo you will be able to control the amount of shafts rotation and move it to a specific position.
They usually have a small dimension and are the best choice for robotic arms. But we can’t connect these motors to microcontrollers or controller board such as Arduino directly in order to control them since they possibly need more current
than a microcontroller can drive so we need drivers.
The driver is an interface circuit between the motor and controlling unit to facilitate driving. Drives come in many different types.
