WEEK 4 - ELECTRONICS PRODUCTION

SPEED :-4 MM/S

it started milling the traces .it came good initially but the traces where not milling properly on right upper edges.

saheen helpED me to sort this situation without redoing it from start by reverse milling and DROPPING the bit more.

yes it worked out and traces came good

SUBSEQUENTLY i uploaded designs of drills and outer cut and proceeded(🚫 do not forget to change the bit to 1/32 for drilling and cutting operations)

setting for each step

• milling ->mill traces (1/64)
• drill ->mill outline (1/32)
• interior->mill outline (1/32)

while operating this ROLAND MODELLA MDX-20 if something bad happens we need to press "view" button home the carriage and after we need to press both up and down button to clear the job queue

how to clear queue

then i sourced the COMPONENTS from our inventory and headed to soldering station

i had experience of SOLDERING through hole COMPONENTS before but smd COMPONENTS are first time.

SOLDERING WORKBENCH

i first soldered the xiao rp 2040 ON TO THE PCB.WHAT WE NEED TO TAKE CARE ATMOST IS BOTH SURFACES ARE ADEQUATELY HEATED BEFORE APPLYING SOLDERING WIRE.

i used both conventional adn reflow to solder remaining components. tinning the pins properly is something we have to take care in this stage.

.

board is ready

arduino ide is already installed in computer. i setup the board and rp 2040 library by following
QUENTORRES documentation.assigned proper port for our baord.

now its time see our board alive!!!
for that we have to understand each gpio of rp 2040.

i prompted this code in chat gpt to get the code

Write code to blink LEDs connected to GPIO pins 26, 0, and 1 in Arduino.

Copy

// Define the pins for the LEDs

const int ledPins[] = {26, 0, 1}; // GPIO pins 26, 0, and 1

  

// the setup function runs once when you press reset or power the board

void setup() {

// initialize digital pins as outputs

for (int i = 0; i < sizeof(ledPins) / sizeof(ledPins[0]); i++) {

pinMode(ledPins[i], OUTPUT);

}

}

  

// the loop function runs over and over again forever

void loop() {

// Turn on each LED one after another

for (int i = 0; i < sizeof(ledPins) / sizeof(ledPins[0]); i++) {

digitalWrite(ledPins[i], HIGH); // turn the LED on

delay(100); // wait for a second

digitalWrite(ledPins[i], LOW); // turn the LED off

delay(100); // wait for a second

}

}
Copy

code to blink all 3 leds -from chat gpt 3.5

upload the code pressing compile and upload button in arduino ide

the result
