#L298n motor driver labels driver#
When i share the grounds: ARDUINO + DRIVER i get inconstant voltage flow about ± 2 Volts… then if i touch some metal part of the arduino it goes UP. Here is the 2 circuits versions attached in jpg and smaller size.Īlso thinnk the dropbox folder link is better to see all them in thumbnails, because of the video too… I have recorded a video of tha circuit too, as you can find here: since it only needs 2.5V in its base to switch on (notice the label. The variation that have voltage variations when i touch it witg my hands is that one: The L298N motor driver is easy to use and cheap, with a peak current capability of. The circuit that is stable and have low output is that one: I tried to make an variation of this main scheme and i got 2V but when i touch with my hands in the metal parts of ARDUINO it goes up to 3.5 or 4 Volts…Īll photos and video can be found here: Dropbox - Error It is widely used in controlling robots as we can connect up to four motors at once but if we want to control the speed and direction as well then it allows two motors to be connected. The problem is no matter what i do i never get an output of more than 5V. The L298N motor driver module is very easy to use with Arduino and relatively inexpensive as well. use pwm to control motor speed through enable pin setting IN2 low connects motor lead 2 to ground It is a high voltage, a high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. setting IN1 high connects motor lead 1 to +voltage The L298 is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. #define IN2 4 //IN2 on pin 4 controls other side of A
#define IN1 2 //IN1 on pin 2 conrtols one side of bridge A #define ENA 5 //enable A on pin 5 (needs to be a pwm pin) Motor Driver 2A Dual L298 H-Bridge: Motor Driver 2A Dual L298 H-Bridge - US $4.00 : HAOYU Electronics : Make Engineers Job Easier
My arduino model is Freeduino - Freeduino is a collaborative open-source project to replicate and publish Arduino-compatible hardware files. I do already checked the 12v font supply and it’s fine, also the 5v (from arduino to the l298n driver) is fine too. But i have tried all possible combinations and none went fine. The objetive is simple: control via PWM (Arduino->L298n) a 12V motor fan. I did some photos and one video of the circuit to help and make it easier to find it out. Could anyone please help me find where is the problem ?
