I'm trying to make an override code

So, for context, I am making a system where the servo motor is constantly on an automatic sweeping motion. The micro:bit sends an analog signal from pin 0. If its high, it will activate an override code Problem is... the override code doesn't work. And the servo either freezes or the override doesn't activate.

here's the entire code, and... I gotta admit, it sucks for a newbie like me

Allready tried helping you you never replied now your crossposting

Smells like GPT Chat.

Oh uh... dang... I slept because of, yeah. Timezones. Apologies yep, I'm guilty for that one~ this is version two tho

im still open to suggestions, I'm kind of new also, please don't expect me to reply immediately, I'm from the Philippines and we might have different active times

1. what device are you using - as in arduino

jermanyOP•4d ago

I'm using an Arduino as the main microcontroller micro:bit for the inputs I plan to use micro:bits for radio I may use a radio receiver or smth but... I'm broke. And as you can see in the pic I use Tinkercad

DarwinWasW•4d ago

What is it you actually want to do ?

jermanyOP•4d ago

So here's my whole plan: - I basically want to make hardware for a TF2 Sentry + wrangler. I thought this is the best idea for my first project You know these stuff right?

DarwinWasW•4d ago

So you want the unit to receive codes - via the Micro from the wireless wrangler

jermanyOP•4d ago

Yep So more details:

DarwinWasW•4d ago

You have created the wrngler ?

jermanyOP•4d ago

Almost, the thing above is a prototype I'm just testing micro:bit as an input The radio function and the gyroscope function will actually be useful You get what I'm saying so far, right?

DarwinWasW•4d ago

Yes - relatively simple

jermanyOP•4d ago

Oh good so can I explain my plans now?

DarwinWasW•4d ago

Yeah sure.

jermanyOP•4d ago

So... what I wanna do is: ✅ Build hardware for the sentry itself ✅ Prototype the receiver and sender with micro:bit code - I kind of did that by experimenting with buttons in the micro:bit Things I haven't done yet: - Radio inputs - Harnessing the built-in gyroscope for aiming - Or, using the buttons for aiming left and right, and tilting up and down for aiming up or down - Experimenting with joysticks - Building the 3D model for the sentry itself (which is already hard if I didn't have a 3D PRINTER YET) - Buying the materials for the project I'm still learning this stuff... well, I got into HTML and heard about Arduino some time ago, this is relatively new to me It is just now that I had enough free time to pursue this hobby lol

breaking tasks out into functions can help organize the code https://wokwi.com/projects/432710592056814593

DarwinWasW•4d ago

@jermany why use a uno - why no use an esp32 with inbuilt wireless and bluetooth ?

jermanyOP•4d ago

Baby steps oh neat, thanks!

DarwinWasW•4d ago

It is more difficult to work an uno receiving information from a micro than just using a stand alone esp32

jermanyOP•4d ago

wait a minute it also uses void setup/loop hold up THANK YOU ALL SO MUCH I picked the right community for this...
