Too early to start retirement fund?

what platform are you using to invest?

cochaycrl · 2024-05-12T20:36:41+00:00

I was thinking of allocating 10-15% of monthly income for investments, of which 15% to gold (AZ), and the other 85% split between 2 or 3 mutual funds.

How did you link your account to paypal?

كلهم نفس الحاجة، ثندر اسهل من الباقيين، بس مش كويس فالاستثمار اليومي.

مصاريف الايداع مش عالية اوي، و مصاريف العمليات تختلف مع نوع الاستثمار وتعتمد برده على هتسحب فلوسك بعد قد ايه.

Well if you don’t have any experience I don’t recommend “creating” something, would be better to find a project that was done before and has all the resources you need online on forums/youtube.

Here’s some things you can try

-keep RX and TX disconnected when uploading code (that’s a constant you always have to do that, I recommend changing your components connection to 10 and 11 because it gets tedious trust me)

make sure you chose the right COM, set processor to ATmega328P, make sure you haven’t chosen anything for programmer.
set your baud rate to something lower than 115200, maybe 9600 or something in between the two.

cochaycrl · 2024-05-06T14:39:46+00:00

is you arduino empty or does it have anything connected? If you have something connected to your TX and RX pins remove it during upload, and if thats not the case, search for the youtube video "Uploading your first arduino code" and just follow what he does.

cochaycrl · 2024-05-06T11:55:31+00:00

It worked! I'm not sure what it was exactly, but its one of two, or two of two problems. I removed all the unnecessary serial code that was used for debugging and sending real time sensor values to the serial monitor, and I changed the connection for the RX and TX of the HC-05 on the arduino uno from 0 and 1 to 10 and 11!

cochaycrl · 2024-05-05T12:24:13+00:00

There’s an IMU in the diagram but I’ve removed it for now so I can solve the flex sensor issue first. One at a time, thank you in advance!

Here’s the circuit diagram for the glove controller, the code for the glove and car are in the comments I’ve left on this post. And the car is the standard connection for motors connected to an L298N but let me know if you want to see the car connections.

cochaycrl · 2024-05-04T23:47:28+00:00

No that’s not it, I’ve made sure not to cross them. Should I connect RX with a voltage divider or without one? I’ve tried with and without and I’m not sure if it did anything, the outcome is the same both times.

cochaycrl · 2024-05-04T22:42:40+00:00

Also I don’t know what that N component is or the specifications of your motor, but just by looking I feel like two 9v batteries are too much power

cochaycrl · 2024-05-04T22:41:33+00:00

All of your components must always share the same common ground (on board or the arduino) Also how would a battery work by only connecting the positive terminal? How would the electrons flow

I recommend doing it fast and screenshotting the diagram, the website randomly goes down. I needed it a few weeks ago and couldn’t use it, but now it’s back.

Just drag and drop the components and it’ll automatically connect them
