Touchscreen Injection Molding Machine

-

hello all, i'm new forum , new arduino. build small automated injection molding machine , had questions how program of these functions. start, want have thermostat on touchscreen cycle speed control , cycle counter while arduino controls solenoids machine's pneumatics. how program arduino 2 things @ once(cycling machine , controlling temperature)? need have 2 arduino unos or mega better suited project. thinking (http://www.adafruit.com/products/376) touchscreen, leave other pins open solenoids , sensors? how go connecting thermocouples arduino , temperature read out on touchscreen , have temperature controlled graphic slider or plus , minus buttons? thank time

to start, want have thermostat on touchscreen

i don't see possible. if put thermostat on touch screen, interfere seeing , using touch screen.

a user interface allows setting high , low temperatures different story.

clear requirements lead clear code. fuzzy requirements not.

how program arduino 2 things @ once(cycling machine , controlling temperature)?

you can't. can program 2 different things close together, there distinct interval. whether interval matters unknown, without knowing how "controlling temperature" , "cycling machine" means.

i thinking (http://www.adafruit.com/products/376) touchscreen, leave other pins open solenoids , sensors?

from tutorial link:
quote
uses digital pins 5-13 , analog 0-3. means can use digital pins 2, 3 , analog 4 , 5. pin 12 available if not using microsd


that's not many pins stuff want do.

i have suggested mega, but:
quote
the shield assembled, tested , ready go. no wiring, no soldering! plug in , load our library - you'll have running in under 10 minutes! works best classic arduino (uno/duemilanove/diecimila). shield work mega arduinos going half speed of uno-type boards because of way mega rearranges pins (there no way around this!) shield not leonardo-compatible


whether "half speed" matters, or not, decide, based on no data.

¿conocéis este proyecto? fvdw-sl 15.3 para raspberry pi. convierte la raspi en un nas. http://plugout.net/viewtopic.php?f=31&t=1880 llevo tiempo intentando encontrar la forma de hacer que una de mis raspberry se comporte como un nas. configurando samba, minidlna, transmision, ftp, nfs, etc. pues con esta distribución lo tengo todo hecho. lo instalé ayer y me tiene soprendido. ahora mi raspi es un nas, hecho y derecho. caracterísitcas. - interfaz web. que cambia en función de si eres el administrador o un usuario. - gestión de usuarios. puediendo dar distintos permisos carpetas y funciones. - gestión de carpetas - vpn - ftp - nfs - webdav - varios servidores dlna como minidlna, townky, etc - varios gestores de descarga como transmision, mldonkey, etc - gestión de periféricos usb como impresoras o webcam. - gestión de cron para automatizar procesos. - creo que se basa en arch linux. por cierto, estoy creando una tarea para que me exporte un archivo txt del dis...

How to format a Get Request

i have external server running mysql. have installed php script that, when accessed http deliver data 1 of tables. works fine browser: code: [select] http://www.seti.net/php/getevents.php i cannot figure out how send command arduino. have ethernetclient library working , can access google in example. when send command through client: code: [select] client.println("//get /php/getevents.php http/1.0"); the server returns: code: [select] </head><body> <h1>method not implemented</h1> <p>get /php/getevents.php not supported.<br /> what correct way format in arduino? i use send temperature web server. note lack of http version , additional blank line after - not sure whether difference important works: code: [select] void  sendtemptoserver() { char getrequest[80]; if (client.connect(server, 80))   {   sprintf(getrequest,"get /cgi-bin/arduino.cgi?reading=%s&arduino_id=23&sensor_id=1",t...

avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
