Raspberry Pi Microwave + bar code Scanner - Raspberry Pi Forums

-

hi! engineering group , working on our senior capstone project microwave bar code scanner , raspberry pi attachment enters in how long product needs cook once bar code scanned. right have our microwave dissembled , original circuit board has been removed. looking way connect touch-pad button matrix our pi. have considered removing original touch pad connector original circuit board , placing on row of pins on our raspberry pi a+, connector won't budge original board. not sure method work, however, don't want rip connector off board. also, need find way power our pi through microwave power connectors don't appear compatible pi of right now. have never used pi before , advice appreciated. here link pictures of our microwave [https://drive.google.com/folderview?id= ... sp=sharing]

wow! you've set difficult challenge , potentially dangerous 1 given high voltages inside microwaves , rf radiation risk.
have no idea capstone project or level in education consider getting professional guidance before taking on task.

how power pi
strip apart 5v usb power supply , connect directly mains feed comes in microwave. fuse on mains side addition here too.

how connect touch pad.
wouldn't. i'd use small touch screen instead of touchpad. way can display virtual touchpad , additional information food stuff barcode scanner reads.

if don't want that, you'll have rip connector off. supply photos of how connects main pcb , maybe can give advice. odds row/column matrix you'll need connect gpio pins , periodically scan pins tell whether buttons have been pressed.

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem

i'm new member. me pls code: [select] void manhinh1(){                              tempc = analogread(adc);   tempc = tempc * 0.48828125;                                          lcd.setcursor(0, 0); lcd.print("nhiet: ");                                      lcd.setcursor(7, 0); lcd.print(tempc);   lcd.setcursor(13,0); lcd.print((char)223);    lcd.setcursor(14,0); lcd.print("c");   if(max > min){     if (tempc > max)            {digitalwrite(fan, low);           lcd.setcursor(2, 1); lcd.print("lam mat.....");}     else if (tempc < min)           {digitalwrite(hot, low);           lcd.setcursor(2, 1); lcd.print("dang suoi...");           delay(10000); }     else if (tempc > min && tempc < max)           {digitalwrite(fan, high);            digitalwrite(hot, high);            lcd.setcursor(2, 1); lcd.print("on dinh!!");}              }    else if (max < min){    lcd.setcursor(0, 1);

LED Strip Code

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
