Hi everyone...I'm planning to create a personal led matrix display for my small computer shop. I had a taste of creating 12x(8x8) led matrix and 74154 using picbasic a month ago. But it took too much of my time building it from scratch (hardware and software)... Although I did not get to do the animations yet...but very satisfying . For my next project I list some of the basic stuffs it should do. Basic functionality and hardware requirements 1. Can receive data from serial communication 2. Display Date/time 3. Temperature 4. Basic animations (scroll left/right/ UP/Down and text on center display) 5. Length of the matrix should be about 2meters long I decided to try Arduino, because of the libraries and many resources of information (to keep me going). Now my question is... I heard freetronics have DMD: Dot Matrix Display 32x16 Red and likewise sureelectronics with their P4 32X16 RG Bicolor LED Dot Matrix Unit. Can anyone advice me which one do you think I should consider purchasing in terms of the product/support/and examples available? I appreciate any input to all.
Hi experts, just want to ask some advice the best solution possible regarding a project in mind. I need to connect at least 25 arduino as slaves which consist of 3 buttons(menu) each. Each buttons will send data to the Master with the following format [from Mcu1 Data2(button2)]. I appreciate any input and advice regarding my project in mind. Please check my attachment.
