| Jan 28, 2019 at 6:53 | comment | added | Jaromanda X | How would pogo pins help rotational symmetry @jsotola? There is a way to get rotational symmetry with the power though photos.google.com/share/… | |
| Jan 28, 2019 at 5:30 | comment | added | jsotola | there is also an issue with magnet polarity ..... the Rx could me a magnet ... the Tx would be a plain metal contact .... the power pins would have to be pogo pins ... otherwise you would not get rotational symmetry | |
| Jan 28, 2019 at 5:28 | comment | added | Jaromanda X | @jsotola - I'll upvote for you :p | |
| Jan 28, 2019 at 5:19 | comment | added | jsotola | upvote for a cool idea ..... i would give you another upvote, if i could, for including the information about soldering the magnets | |
| Jan 28, 2019 at 5:18 | comment | added | zen Sutherland | Oh, wait. Yes. If i have the Tx pin on the left and the Rx on the right, the two match each other's Rx and Tx. Sorry, i got confused. Thanks so much for your help and for having to suffer through my confusion! | |
| Jan 28, 2019 at 5:16 | comment | added | Jaromanda X | not sure why you'd need 4 - the key is rotational symmetry | |
| Jan 28, 2019 at 4:33 | comment | added | zen Sutherland | Hmmm... so maybe i need to use 4 pins for each side to be able to communicate back and forth serially? My mind's boggling a little. | |
| Jan 28, 2019 at 4:24 | comment | added | zen Sutherland | Yes, 9600 would be quick enough... | |
| Jan 28, 2019 at 4:23 | comment | added | zen Sutherland | Well, dang. I would need each of the modules and their faces to be identical as far as wiring, meaning that any face to be magnetically attached to any face. You're right, i can't connect Tx to Tx if i expect to read anything... | |
| Jan 28, 2019 at 4:21 | comment | added | Jaromanda X | don't use high speeds though ... but it looks like you won't need to - I believe 9600 would work | |
| Jan 28, 2019 at 4:20 | comment | added | zen Sutherland | Sweet! That looks like maybe the ticket. Thanks for the pointer! | |
| Jan 28, 2019 at 4:20 | comment | added | Jaromanda X | by the way, I'd wire it differently ... if 1 is output and 2 is input, for example, then you'd need, for example 1 on top of 2 on the left of the board, and 2 on top of 1 on the right ... therefore, output connects to input and vice versa :p | |
| Jan 28, 2019 at 4:19 | comment | added | Jaromanda X | arduino.stackexchange.com/questions/43118/… shows 4 software serial in use | |
| Jan 28, 2019 at 4:17 | comment | added | zen Sutherland | I would need them to transmit or receive a value such as 1 for green, 2 for red, 3 for blue or something similar. Decision-making by the arduino would determine if that value was passed to another face. (It's sounding weirder and weirder). | |
| Jan 28, 2019 at 4:14 | comment | added | Jaromanda X | so, your wiring shows each "arduino" using 3 pairs of wires to connect to an adjacent "arduino" - so, how did you envisage these wires would be used for "communication" | |
| Jan 28, 2019 at 4:14 | comment | added | zen Sutherland | Does 'SoftwareSerial' allow multiple Tx/Rx pin sets? That does look promising! | |
| Jan 28, 2019 at 4:11 | comment | added | zen Sutherland | Hmmm... since the rest of the project is only LED lighting with not much programming, I was hoping to use a cheap, low-power (usually 1 serial interface) arduino like the lilypad or similar. I would be creating some 30-40 modules to interact and so the cost of each is thusly multiplied. | |
| Jan 28, 2019 at 4:09 | comment | added | Jaromanda X | you have more than one serial interface - some arduinos have 4 hardware serial interfaces (if I recall) ... then there's SoftwareSerial - to make any pair of pins a "serial" interface | |
| Jan 28, 2019 at 4:06 | comment | added | zen Sutherland | As long as i was only communicating to one face of the module at a time, but my understanding of the Tx/Rx communications would push out the command to all modules. I only want to send/receive to one module, not all of them at the same time. | |
| Jan 28, 2019 at 4:01 | comment | added | Jaromanda X | would serial connections work for you? | |
