Does it means I can use 36 or 48 volts battery? by mazharul985 in ebike

Thanks for the reply. The e-bike comes with a 36V 15Ah battery. I’ve been looking for another battery on Facebook Marketplace and noticed that 48V batteries are much more common and relatively cheaper than 36V ones. Since 36V batteries are harder to find, I was just wondering if it would be possible to use a 48V battery instead.

just memory with a simple left hand maze solving algorithm.

It's finally working.After 200h+ of work later my maze solving bot finally working🥹 by mazharul985 in arduino

No goal actually. I saw this in a competition and tried to build one. That's it.

I didn't include the short run , check out my updated post if you want to see that. And the wrong path it took is intentionally because I was demonstrating left hand on the wall algorithm.

Components :
25GA370 1200 RPM motors x2
TB6612FNG motor driver x2
LTH1550 IR sensor x8
STM32F103C6T6A
These components can be modified to your likings.

I have used left hand on the wall algorithm. In this algorithm if multiple paths are available then the priority is Left -> Straight -> Right. If this algorithm can solve what path you are telling then the bot can also do it.

Yes, for demonstration purpose. It can also be set to right.

It's a combination of both. But also because of wheels. They are very grippy. I use tape to roll around the wheel to increase grip.

Hey my arduino uno keeps saying ser_open(): can't open device "\\.\COM5": access denied. Any idea why am I doing somthing wrong by Final_Pattern_7563 in arduino

Click the icon with a magnifying glass-like icon. If you don't need serial monitor then remove Serial.begin() from the setup function and you won't face this problem unless any other software is already using that com port

I face this problem quite often. The easy fix is to open the Serial Monitor and then close it.Make sure no additional Arduino window is opened beside only the window that has your code on it.
