How to use MOSFET Button IRF540 to control 5A to 20A DC Motor or LED light strip

[@bernhard_derProtoTyp]

Hello, thank you for making this video! I bought the exact same boards (as it looks) to controll four quite short 24V LED strips (20cm) with a Arduino Nano clone (5V PWM signal) I failed to make the strips dim low. It works fine for turning them on and off completely but I suspect that there is some sort of ringing problem that prevents the MOSFET to turn off completely in the low portion of the duty cycle. Same Code works as expected with different MOSFETS. also my board got quite hot in the indicator light section on the left. The mosfets barely got warm fortunately but still the 105degree Celsius copper traces on the left don´t seem right to me. same on several boards I testet. I bought them from aliexpress. there are also some being sold that are missing the diac diode. I found no difference in their performance. I had some success bridghing the 100K resistor on the input side with a 10K resistor but I know too little about the subject to propose that as a propper solution. Just wanted to let you know about my issues and anybody having the same problem that are finding this video, as I did :).

Nice video. Thank you for posting it.

What kind of signal really the motor or loads are getting or what is the output signal? Is it a DC or pwm signal output?

[@robojax]

Any time you control the speed of a motor, the best method is to used PWM. It is PWM

[@lucasianii8178]

May we please have the schematic diagram of the module so that if should i need to build my own i can do so?

[@robojax]

get it and draw it yourself. I purchased it.

[@jinturenji1285]

Can we use this module to build an inverter to drive ac loads

[@robojax]

not sure. but this is only for LOW side. I am not sure about your design but most of the time you need switch (MOSFET) for both high side and low side.

[@jinturenji1285]

@@robojax is there any driver module for HIGH side

[@conorjh89]

can you run this module in reverse... ie 4 inputs into 1 output? i need to switch between multiple batteries as the capacity drains

[@robojax]

Each input is separate and do however you want yo connect them.

[@luism.mendoza9984]

I suppose that the module varies the output voltage since it is required by the bulb and the motor to work. Does the module work for an solenoid PWM valve where it is necessary the output current varies, not the voltage.

[@robojax]

No the module doesn’t change the voltage. PWM is not changing the voltage. It is just turning it on or off at certain intervals to make the motor move slower or faster.

[@tombonge]

Do you need to add a diode for a DC motor or are the diodes already on the board?

[@robojax]

tough question. Some datasheet says that the body diiode of MOSFET is enough but some say not enough. My understanding is that you don't need external diode with power mosfets.

[@kyouhyung]

Is it possible to drive an RGB LED strip with this module? I ordered one of these, but I'm not sure how I should wire it.

[@simon057]

im in the same situation. I have this board and an esp8622 but i can't turn on the lights

[@신창민-d3o]

8:40 is it possible to change direction if I connect both (ch1. + and ch2.) (ch1- and ch2 +)- to a motor and turn on ch1, turn off ch2 and next step turn off ch1 and turn on ch2 ?

[@robojax]

Hi, I believe I mentioned somewhere in the video, that you can't change the direction. I know changing direction of rotation is important and before making video I thought it. But this module can't do that. The design doesn't allow it.

[@jd-qy1mn]

my mosfet is not receiving signal from arduino please help

[@jd-qy1mn]

it was initially working well

[@jd-qy1mn]

it keeps sending voltage to out 1 man i need serious help

[@robojax]

my friend, you give very little details. no one can help you. Please post the wiring diagram on this page snipboard.io and then post the URL (address of image) back here under the video so I look at it.

How to connect a Stepper engine to this bridge ?

Yea learn it from this video kzbin.info/www/bejne/mYq3enagaamKj8U

Hi!!! I am planning to use similar board /HW-153 v1.1/ which will be controlled from frequency generator 1Hz to 150KHz. I want to use this set up to control petrol injectors for cars. But i am little confused with wiring on this board... Can you help me?

[@robojax]

Hi, it can’t be explained better than this. I just watched I have even show wiring. Your injector is a load the same as motor or LED. So what else you want.

[@desislavkanev9613]

@@robojax on the 3 pin terminal we have minus,plus and signal. Signal comes from pwm frequency generator. Another two pins plus and minus ? What voltage i must apply on this terminals? On other side M1 is power supple / 12v/ , M2,M3,M4 and M5 are outputs for load/injectors/ is that right?

[@robojax]

I don’t remember. Watch the video I never skip those details.

[@FirstLast-tx3yj]

@@robojax so if i use this module on a 12v circuit and this module with replace both the relays and fuses But when the fuses are removed there is no protection to the circuit!! Please correct me if I am wrong

[@JP-fv1id]

why does my dc power supply drop when i connect it to the mosfet? It was running good at first not sure what happen

[@robojax]

Check the current. May be there is short circuit

[@jd-qy1mn]

@@robojax ok i think i may have messed up apparently one of my dc motors is shorting the circuit what can i do sir

[@robojax]

it should not shorten. it seems the motor need lots of power which your power supply can't supply. test it by connecting it directly to the power supply.

[@JP-fv1id]

@@robojax ty sir problem solved

[@codebeat4192]

Use #define to declare 'constants' instead and use capital letters. Now you are using ints(!) and waisting two bytes of memory for each declaration that isn't necessary to do so.
