The most common method to drive DC motors in two directions under control of a computer is with an H-bridge motor driver. Sign up using Facebook.
Quadruple Half-H Drivers
I thought they might be the ones everyone knows about connecting across an inductive l93ne when switching it with a transistor, but the data sheet says both varieties are good for inductive loads See notes below for a two Arduino pin solution. Sign up or log in Sign up using Google.
There is an L and an LD part number. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Email Required, but never shown. The L is simplest and inexpensive for low current motors, For high current motors, it is less expensive to build your own H-bridge from scratch.

The L comes in a standard pin, dual-in line integrated circuit package. Hook up the circuit and run your motor while keeping your finger on the chip.
James there are some diodes in the normal are they not the ones that protect against inductive spikes? Assume you have only one motor connected with the enable tied to Arduino Pin 3, and the two direction controls tied to Arduino Pins 4 and 5.
Post as a guest Name. A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: Pick the “D” version because it has built in p293ne diodes to minimize inductive voltage spikes. Since you’re going to drive a motor you will want to use clamping diodes to avoid inductive spikes from the motor killing the output transistors in the chip. James, yes I see from the data sheet that there are extra diodes in the Datasehet, but exactly what protection do they provide?
Pin 1 is at the top left when the notch in the package faces up. Help me please and thanks you so much for your attention.
If you can only find the LNE you can add your own diodes. What is the difference even google could not tell me?

I see too, that the the D can only handle mA compared to 1A. If you are only using one motor, leave L pins 9, 10, 11, 12, 13, 14, and 15 empty. Each motor takes 3 Arduino pins. H-bridges can be built from scratch with bi-polar junction transistors BJT or with field effect transistors FET datxsheet, or can be purchased as an integrated unit in a single integrated circuit package such datashet the L They are much cheaper datashedt a new If it gets too hot to touch, you can’t use it with your motor.
Personally I still use external diodes with the D. LD has output clamping diodes for inductive transient suppression while the LNE does not. I prefer going to an ICs datasheet: See the datasheet for how they are connected.

The L is limited to mA, but in reality can only handle much small currents unless you have done some serious heat sinking to keep the case temperature down.
Note to Datasbeet students: The pinout for the L in the pin package is shown below in top view. Unsure about whether the L will work with your motor?
The following schematic shows how to connect the L to your motor and the Arduino. Actually i just want to control dc motor rotation direction, it turn left or right So, the tutorial i found in this link below http: The diodes in the D are indeed there to protect datasheft inductive spikes.

So presumably they serve some other protective purpose? The L is an integrated circuit motor driver that can be used for simultaneous, bi-directional control of two small fatasheet.
