SERVO MOTOR CONTROLLING, USING L293D MOTOR DRIVER SHIELD

Motor Driver Shield is a board which gives possibility to control 4 DC motors or 2 step motors (unipolar or bipolar) and 2 servo motors additionaly by stacking on Arduino.
There are 2 L293D motor driver IC on board which means it can drive 0.6A 4 seperate DC motors or 0.6A 2 seperate step motors. You can control speed and direction of motors independently. Motor controls are done by AF Motor Library.
Features:
5-12V operating voltage
L293D motor controller
Independent control of 4 DC motor
Independent control of 2vstep motor
3-pin socket for 2 servo motor
0,6A constant current on each channel
Free analog input pins for sensor connections
Compatible with Arduino Uno
Product Dimensions: 69x53x14,3mm
Weight: 32g
Power:
Motor Shield must be feeded only externaly. Because necessary motor current will mostly be over the maximum current which USB can give.
External feeding can be done with adapter or battery. Adapter can be connected to 2.1mm centre positive power socket on Arduino or EXT_PWR screw terminals on driver - be carefull about polarity. But it is always advised to give power through screw terminal on driver. Because when it is given through power socket on Arduino, current which is drawing by motors will reach driver through Arduino. Since, Arduino Vin route is made for maximum 1A current when current is above 1A, Arduino board might get damaged. That is way external power should always be given through screw terminal on driver.
EXT_PWR screw terminal on driver is connected to Vin pin through header which means when power connection is made through screw terminal, Arduino will get the power through Vin pin and step down it to 5V with the regulator on itself. This way, you do not need 2 different power source. But as you know Vin pin on Arduino only accepts inputs between 7V and 12V. In that case if voltage given to driver card is between 5V and 7V, Arduino will not work properly since the input voltage is below the regulator's minimum operating value.To avoid this, there is a power jumper under the driver card. This jumper connects EXT_PWR screw terminal on driver and Arduino Vin pin. If the voltage on driver is between 5V and 7V, jumper will be removed. EXT_PWR and Arduino Vin pin will be seperate and Arduino is feeded with 5V externally. If voltage given to driver card is between 7V and 12V, jumper stays the same and boards can be used.
There is 3-pin servo socket on board to drive two servo motor. Servos get their 5V through 5V pin on Arduino. Small servo motors such as SG90 can be used with direct connection. But if larger servo motors will be used, 5V regulator on Arduino will not be enough. In that case, + route which goes through 3-pin servo socket should be cut and external 5V should be given to servos.#L293d#l293d expansion module #l293d shield #l293 arduino tutorial #l293 motor tutorial #l293d motor tutorials#arduino line follower #arduino easy project #servo with l293d shield #servo control by l293d motor driver shield #arduino uno #l293d motor driver arduino

Kitne dc motor laga sakte he ( HELP)

[@nilimakulkarni4541]

i m trying to control 5 motors with bluetooth, UNO and shield.
but when i use bluetooth app it gets disconnected.
can you give me reason?

[@YPTechDATIA]

I think there is some issue with the battery, when the load exceeds the connection lost.

[@nilimakulkarni4541]

sir,i tried many options for powering hc05.
used separate battery for it,
used 2 arduinos 1 for servos n another for hc05.
individually tested bt n shield with servos.they are working.
but not together.

@nilimakulkarni4541 Oh . I am sorry I can't help since I need to check it personally and that is not possible .
