I prefer going to an ICs datasheet: The L is an integrated circuit motor driver that can be used for simultaneous, bi-directional control l2993ne two small motors.
If it gets too hot to touch, you can’t use it with your motor.

Johannesburg hams call me: Sign up using Facebook. Personally I still use external diodes with the D. The following schematic shows l293nne to connect the L to your motor and the Arduino. The pinout for the L in the pin package is shown below in top view.
The most common method to drive DC motors in two directions under control of l293n computer is with an H-bridge motor driver.
What is the difference even google could not tell me? 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.
LD has output clamping diodes for inductive transient suppression while the LNE does not. I see too, that the the D can only handle mA compared to 1A.
Pin 1 is at the top left when the notch in the package faces up.
Quadruple Half-H Drivers
If you are only using one motor, leave L pins 9, l293nr, 11, 12, 13, 14, and 15 empty. Tutorials on that site are have been known to be wrong. 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.
The diodes in the D are indeed there to protect against inductive spikes. See the datasheet for how they are connected. 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. Help me please and thanks you so much for your attention. Hook up the circuit and run your motor while keeping your finger on the chip.

Dagasheet thought they might be the ones everyone knows about connecting across an inductive load when switching datashewt with a transistor, but the data sheet says both varieties are good for inductive loads The L is limited to mA, but in reality can only handle much small currents unless you have done some serious heat l29n3e to keep the case temperature down.
Home Questions Tags Users Unanswered. Unsure about whether the L will work with your motor? If you can only find the LNE you can add your own diodes. The L comes in a standard pin, dual-in line integrated circuit package.

They are much cheaper than a new Capacitor Expert By Day, Enginerd by night. Data sheet PDF fileKb.
H-bridges can be built from scratch with bi-polar junction transistors BJT or with field effect transistors FETor can be purchased as an integrated unit in a single integrated circuit package such as the L See notes below for a two Arduino pin solution. Actually i just want to control dc motor rotation direction, it turn left or right So, the tutorial l293nf found in this link below http: Sign up or log in Sign up using Google.
Sorry for my poor english.
