Can I further connect Relay (Normally Open & -ve) to railroad turnout (total 4 sets) and if so, do I have to connect / give external power supply to Relay and if so, how much VDC and Amp required ?

[@Unboxing.Channel]

i didn't understand

[@sushildamle3449]

Thanks a ton. I. Wanted to do similar as shown in the following video:kzbin.info/www/bejne/hYvaaaGViNOSm6c. They have shown only one turnout, instead i wanted to add one more turnout and LED signals (only 4 LED's will be ON at any given time). Hence wanted to know how much external power i will have to give. Just for your knowledge i am a retired person from ceramic field and train is my hobby. I do not have any education in the field of electronics. Hence. Please guide me in this regard. Thanks in advance.

[@Unboxing.Channel]

yes you can do this just you need the code

[@WrappedInPlasticine]

Can you make a video on controlling the relays from a PC? As in can you make a video on sending commands to the Arduino so the arduino will activate whichever relay it's told to do?

[@Unboxing.Channel]

you need another module

[@WrappedInPlasticine]

@@Unboxing.Channel can you please make a video teaching us how they talk to one another?

[@Unboxing.Channel]

i ' m sorry bro i can't now to next time

[@ericlessard5021]

Can someone help me? I need to control 4 relay with a 4 axys joystick. On position 1 of the joystick, 3 relay need to be on. On position 2, 2 relay need to be on. On position 3, 2 relay beed to be on. On position 4, one relay need to be on. Those relay will control some hydrolic valve...

[@Unboxing.Channel]

is difficult

[@ericlessard5021]

@@Unboxing.Channel i did it without arduino finally... Thank anyway

[@Unboxing.Channel]

i'm so happy for that

👍👍👍

[@Jamshaid.Electric]

You need external power supply for medual Arduino 5v regulator will burn after get heat

[@Unboxing.Channel]

yes of cours

[@subrotoxing8214]

if you are only doing one channel at a time like this it will be fine... in fact up to 3 is fine .... it is trouble when you go more than 4... like powering all 8 channels at the same time.

[@Unboxing.Channel]

😘

Hello, sirr! just asking why my 4 relay are not responsing by putting them on pin 2,3,4,5 of the arduino while the other 4 are working on pin 8,9,10,11

[@Unboxing.Channel]

could you send problem in short video

good job buddy

thank you bro😎

I am using 12v 8 channel relay with arduino nano Now i am confused about wiring. Vcc and gnd with that are with input pins of relay to 5v and gnd or Arduino Now what to do with the vcc and gnd and jdvcc that are on right side

[@Unboxing.Channel]

just connect them

[@mowerdog]

What does the yellow jumper do?

[@Unboxing.Channel]

its connect with one of them i mean relay

[@madbrit5053]

It make the relay use an external power for the output side to power the relay so the optical relay is still safe, no direct connection, otherwise it used the input from VCC on the side, no point in the optocoupler as it would make a direct connection

[@dmitrys.4741]

@@madbrit5053 I don't understand what you are saying ) When I remove yellow jumper, my relay just doesn't work, it doesn't click with 5v applied to the IN pin.

[@Jeff_Seely]

@@dmitrys.4741 The board uses an active low to energize the relay. So you are "sinking" the device to turn it on or in other words when your output pin goes from 5v to 0v, the relay position energizes and that is precisely what is happening when you watch the video. The reason why this is done this way is because it is safer to the chip to sink the device than to source it with current. Get used to the sinking method when working with microcontrollers and you'll save some money in blown boards. Here is the datasheet for this board to help you along and search the internet for understanding sinking circuits if you need further help. Good luck! www.elegoo.com/tutorial/Elegoo%208%20Channel%20DC%205V%20Relay%20Module%20with%20Optocoupler%20for%20Arduino%20UNO%20R3%20MEGA%202560.pdf

[@jvon3885]

The yellow jumper is able to be seen jumping from one spot to another, whereas the grey jumper is harder to spot jumping. Hope this helps.
