HC-05 Bluetooth Module: HC-05 is one of the commonly used Bluetooth devices that uses UART communication protocol. It is a dual-channel H bridge motor driver IC which can be easily used to drive two motors. Maximum Operating Temperature: -40C ~ 125C 2 DC Motors L293D Motor Driver IC: The L293D IC is a powerfully built motor driver IC.Lead Free Status: Lead free / RoHS Compliant.Tested compatible for Arduino Mega, Diecimila & Duemilanove.2 external terminal power interface, for seperate logic/motor supplies.Pull down resistors keep motors disabled during power-up.Can drive 4 DC motors or 2 stepper motors or 2 Servo. 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC. The L293D is a 16-pin Motor Driver IC which can control up to two DC motors simultaneously, in any direction. 2 interface for 5V Servo connected to the Arduinos high-resolution dedicated timer - no jitter.Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.Up to 4 bi-directional DC motors with individual 8-bit speed selection.Can drive 4 DC motors or 2 stepper motors or 2 Servo.2 interface for 5V Servo connected to the Arduino's high-resolution dedicated timer - no jitter.Like that chip, you get 2 full H-bridges, but this chip is better for low. This motor driver chip is a nice alternative to the TB6612 driver. Spin two DC motors or step one bi-polar or uni-polar stepper with up to 1.2A per channel using the DRV8833. The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. Adafruit DRV8833 DC/Stepper Motor Driver Breakout Board.Basically this means using this chip you can use DC motors and power supplies of up to 36 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge.L293D is a monolithic integrated, high voltage, high current, 4-channel driver.The pin is made Arduino compatible, convenient enthusiasts quickly Arduino-based development. This is a common DC motor drive module, L293D the chip small current DC motor driver chips. Here a motor can drive a variety of simple to a slightly complex projects full function expansion board. I build a Buetooth RC car with 2 motors using the next parts: -Arduino Uno. Arduino is a good entry-electronic production, with motor expansion board can be a good robot development platform. Hello, I just finished my first Arduino project and I am facing a little issue.
