DFR0144 V.1 (I presume)
foxm 2017-07-13 05:56:32 3481 Views5 Replies Hi guys, I'm new.
I have a DFR0144 not V2.1 but this: https://www.dfrobot.com/wiki/index.php/File:DFR0144.jpg.
I bought this shield 5 years ago.
I would like to know some kind of things, if you can help me.
1st: I have to solder 7 Pin Header Connector on "GND 5V D5 D4 D3 D2 VT" holes? the shield does not have pin connectors on.
2nd: I want to connect a PushButton to Arduino Uno, for activating 1 of 4 relays
(for example, to activate a DC motor to open an electric gate); I think I can connect button on DFR0144 shield but I don't understand where.. i.e: on arduino uno i connect the button on digital pin 2.. and programming some kind of output, but with shield is stacked on Arduino I don't be able to use it. How can I do this? Which are pin occupied by stack and which are free?
3rd: This shield is I/O shield or just output? I presume input and output but it's a little hard to understand for a newbie like me.
I don't have too problem with programming, just I'm not so expert on electronics.
I understand my questions are so simple, but using "Search" don't helped me so much.. and my english is so poor.
I will appreciate a lot your help anyhow.
Thankyou friends

2017-08-02 01:00:22 These pins are the same as D2,D3,D4,D5 and VCC, GND, they are the expanded pins robert.chen
robert.chen 2017-07-15 08:43:37 No, I just want to know what this connector is.
And, eventually, how to use it.
In the meantime I'm using a 1ch relay, but as I want to make a circuit
that opens a 2 doors gate, and pilot other equipment at the same time
I want to avoid inserting many 1ch relays and use my DFR0144.
something like in pic.
Thankyou.. and sorry for my poor english foxm

foxm 2017-07-15 02:11:40 Hi
I am so sorry that I can't understand your 1st question correctly, do you mean you want to connect all the four relays? Could you give a picture for better demo? robert.chen

robert.chen 2017-07-14 04:27:37 Yes, thankyou.. I start to understand.. slowly slowly
About my 1st question? I have to use the holes and eventually how?
thankyou foxm

foxm 2017-07-14 02:11:14 Hi,
This is an IO expanded shield with 4 channel relay , you can control 4 relays from the green terminal, if you want to use the 4 relays, you can connect to the relays separately, the COM1~4 correspond to digital pin 2~5,，you can use screwdriver to connect like motors to the green terminals.
If you want to connect push buttons, please don't use D2~D5
The pins on the shield is the same as the pins on Arduino, you can see them as the IO pins robert.chen
