L293D Motor Direction Controller

f0uiidbit9pphrc-medium

baelza.bubba @ instructables.com show us how to build a DC motor direction controller using L293D.

I designed this DC Motor Direction Controller so that I could give direction control to DC motors that I am building into mini tools (drill, lathe, table saw, solder smoke extractor, etc.). While, I don’t need direction control for all of the tools that I’m building, it IS necessary for some. Plus, who doesn’t want to spin their DC motor backwards?

ATtiny based bidirectional motor control using L293D

Rahul @ Xanthium has posted a tutorial on interfacing ATtiny with L293D:

In this tutorial we will learn to interface L293D with ATMEL ATtiny microcontroller and control them bidirectionally.The microcontroller used here is ATtiny2313A which is interfaced to two L293D motor control chips for controlling upto 4 DC brushed motors.You can control upto 8 motors if bidirectional control is not needed.
The ability to control upto 4 motors is essential when we are building 4 wheel drive robotic projects like Rovers or under water ROV’s.

Dual DC Motor driver using two L293D

Dual-DC-Motor-driver-for-robot-using-L293D-DC001

Dual DC Motor driver using two L293D IC. The L293D device is quadruple high-current half-H driver. The 293D is designed to provide bidirectional drive current up to 600mA a voltage from 5V to 36V. It provides 600mA +600mA on each channel suitable for mini hobby robots. The board been designed mainly for small size robot, however this can be used for other application where two motor control required. L293D includes the output clamping diodes for protections. Each channel required two input signals PWM and DIR for full control. Separate logic supply to reduce dissipation.

Specifications

  • Motor/Logic supply 5 to 36 V
  • Logic controls input 7 VDC max
  • Inhibit facility/enable
  • PWM Frequency 5KHz Maximum
  • High Noise immunity
  • Over temperature protection
  • Capable of delivering output current up to 600 mA per channel
  • The control/interface lines are accessible with Berg connector
  • Header connector for motor and supply connection

L293D Motor Controller Tutorial

FL0ARNEIHUUE4KR.MEDIUM

Sooncheng @ instructables.com shows us how to control a DC motor using the L293D IC and an Arduino:

L293D is a chip that enable us to control two motors together with only one Arduino board or other microcontrollers. However, I was having a project that required controlling four DC motors together. Recently i brought a L293D Arduino Shields , it covered all of my pins that i need to use them to connect with other breakout board to combine with the motor controller (of course you can buy a L298N motor controller) . I made it, so i decided to share it with u guys now. So let’s get started.

MagSpoof – Wireless credit card/magstripe spoofer

magspoof

MagSpoof is a device that can spoof/emulate any magnetic stripe or credit card you currently own. It can work “wirelessly”, even on standard magstripe/credit card readers, by generating a strong electromagnetic field that emulates a traditional magnetic stripe card.

Note: MagSpoof does not enable you to use credit cards that you are not legally authorized to use. The Chip-and-PIN and Amex information is not implemented and using MagSpoof requires you to have/own the magstripes that you wish to emulate. Simply having a credit card number and expiration is not enough to perform transactions.
