Motors are rated at certain voltages and can be damaged if the voltage is applied to heavily or if it is dropped quickly to slow the motor down. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. In motors try to imagine the brush as a water wheel and electrons as a the flowing droplets of water. * Pulse Width Modulation is a means in controlling the duration of an electronic pulse. H-Bridge's are typically used in controlling motors speed and direction, but can be used for other projects such as driving the brightness of certain lighting projects such as high powered LED arrays.Īn H-Bridge is a circuit that can drive a current in either polarity and be controlled by *Pulse Width Modulation (PWM). Other Extensions: control of direction indicators, the logic part of the plate to take power interface. Storage temperature: -25 Deg C ~ +130 Deg C
Maximum power consumption: 20W (when the temperature T = 75 Deg C) The logical part of the operating current range: 0 ~ 36mA The logical part of the terminal supply area Vss: +5 V ~ +7 V (can take power within the board +5 V) In that cas the shield doesn't nothing Arduino is magic sometimes.The L298N driver module, using ST's L298N chip can directly drive two 3-30V DC motor, and provides a 5V output interface can 5V single-chip circuitry to supply, support 3.3VMCU control, you can easily control the DC motor speed and direction, you can also control the 2-phase stepper motor, smart car essential.ĭriver: L298N Dual H Bridge DC Motor Driver ICĭriven part of the terminal supply area Vs: +5 V ~ +35 V such as the need to take power within the board, the supply area Vs: +7 V ~ +35 V One theory is that I adjusted the tension of my power supply under 5V. I don't know why but now, the shield works too, I mean : Problem solved. I did tested the PWM with an oscilloscope and a multimeter, the arduino PIN I was using worked correctly. I feel a bit stupid with what I did with the grounds, it seems wrong t me but I don't know what to do instead :/ What can I do ? My goal is to have the best possible control of the speed of that DC motor in term of reactivity, does a L298N is suited for that ?

Now here is the problem I have : With the scheme I've shown above, it simply doesn't work, nothing happens when I set the grounds in common, why ? Then if I remove the cable that goes to the arduino ground, it works but the motor has a very low torque, it seems also that there is a kind of latency in regards to what display the Serial monitor.
This prooves at least that my shield isn't damaged. If I doesn't use the Enable output of my Arduino and just use the jumper instead, the motor turns with a good torque. I'm aware that, maybe if the value is too low, the motor will have trouble to start so I "help" it manually. With that code, the speed of my motor should progressively increase and then goes back to 0.

Now here is the code I'm using : #define CONTROL_M 9 // To Enable inputĪnalogWrite(CONTROL_M, i) // Any value between 0 and 255 I don't care about the sens of rotation, so I set IN1 to 5v and IN2 to the ground, is it right to do it like that ? The power comes from a transfo with an adjustable voltage of ~7v 1.0 Amp.
I try to control the speed of a DC motor with a L298N shield but it doesn't work very well.
