Hey Guys & Gals,
so was trying to run one motor via L298N which was connected to Arduino UNO but when i commanded the motor to rotate from clockwise manner( forward) to anti-clockwise manner (backward), the led on the L298N board and the led on my power supply ( 24V , 2A) started blinking, i tried resetting the arduino, disassembled and again assembled the setup but yet i am facing the same problem any help regarding this query is appreciated :)
plz message, if you find any above mentioned data is insufficient or do u have any doubt regarding my stated question
If you're putting 24V DC raw motor supply into the L298N, then the 5V_EN jumper (if you have one on the L298N) needs to be disconnected - in order to prevent damage to the L298N regulator. And if you disconnect that jumper, the L298N board's logic circuitry will then have no 5V power, which is normally needs to drive its logic circuitry. This would then mean the need to connect an external 5 Volt DC supply to the "5V" pin of the L298N.....needed to power up the logic circuitry.
However, supplying 24V DC to the L298N can often create a problem.... since the L298N has a power handling limit of 20 to 25 Watt. So if your motor has say 20V across it, and the current through it is relatively high..... then your L298N board might not work properly unless you drop the raw motor supply voltage.
