Thank you! I wasn't sure how to wire it because it had only 2 terminals on one side and 3 on the other side, your video was the only help I could find!

can you use an ESP32 to control the motors wirelessly with another ESP32?

hi, thanks a lot for the video, very clear for newbies like me and easy to follow!. What i don't get is the need for the diodes. You say that "if you use a DC motor you need to add a diode". Why is that? is it true if you use a DC motor and a DC power supply? Also, in the rest of the video, i don't see you add the diode in your schematics.... Can you clarify a bit further? thanks!!

@@22chrs @Jean Gustang Baguette hm, i thought I had answered this morning... The reason is that a DC motor is an inductive load. You can find a web with this and more information about this module if you Google it. I tried to post it a couple of times but my post gets deleted

@@22chrs google "flyback protection diode". When a DC motor turns off, it keeps spinning for a little bit, and now instead of taking voltage, it generates voltage. You don't want it to generate that voltage into your relay/arduino, so you need a diode to protect it.

Hi I am trying to build a BOB BECK zapper the zapper uses three 9 volts batteries in series. a 100k pot is used to control he output . Do you think I can use the mosfet module on your video ??? Can I use a ZK-PP2K driver instead of the Arduino to control the output ??? any tips ???

will these work with common ground? like switching on/off lights in a car? thanx

it's a low side switch, which is to say it goes into the ground or negative wire of whatever you want to control. Like this "battery + -> bulb->mosfet-> -battery " . So it sits in the negative return from the bulb, not the positive from the battery to the bulb (thats a high side switch, you can get them as well) it has its own + wire connected to the battery as well to power it. If you put it into the common ground, interrupting it (between the common ground and the battery negative) then yes it will work, but everything will need to run through it that is also on that common ground, eg starter motor, unless you give that it's own non-common ground. I.E. the battery negative must only be connected to it, if there is another path to the battery negative from that common ground the electricity will just go that way and the mosfet will do nothing. You'd be better off taking whatever you wanted to control off the common ground, running their ground returns to the mosfet instead and then the mosfets neg would connect to the common ground.

@@m3chanist thank you. I already got it. I should have first looked onto the bottom side to realise that it has common + , not common ground. :) So it is not good for the car. thank you. But maybe you know similar mosfet board that has common ground that can be used in a car?

Thank you for the useful information. I have a question. I would like to use a module with a LR7843 MOSFET to turn off the power supply to the coil in the EMR relay (5V, 160 mA max). Do I need to use a diode?

Hi, no you don't need doide. See this datasheet page 2 diode section www.infineon.com/dgdl/irlr7843pbf.pdf?fileId=5546d462533600a40153566de53526d8

Note: Connecting 3x 1A diode is not advisable Use 3 A diode or move on to higher amps. Don't connect diodes in series or parallel.

this is command industry practice to connect diodes in parallel. There is no problem with that. and the same is true for series.

Hi, it depends on your load current. if your laod need 5A, then get 5A diode.
