@lemmy.caLooking to get into Arduino for the first time. Have already searched about this topic, looking to seek some additional input, as you all seem to know what you are talking about. For reference the Elegoo clone is around half the price of the official pack. There is a Elegoo clone of the Mega board (as opposed to the Uno) which is almost as expensive as the official Uno one. Or would I be better off buying parts individually? I apologise for knowing nothing about electronics.
Hey all,
I've been sitting on a starter kit for a Mega 2560 R3 board and sensors for over a year. I want to get into it, so bad, but I frankly don't have the time to learn to code this with my job the way it is.
Is there a WYSIWYG program anyone favors, especially for someone new to Linux (I'm using a Raspberry Pi 3 Model B running Raspbian and I have a Raspberry Pi 4 Model B too) and Arduino (board model Mega 2560 R3)?
I found these options. Anyone have experience with them?
Here is my new serial starting code.
It takes some time to start printing the serial after the command is set. Usually you simply add a delay, but that delay can be longer than the time your serial takes to connect, so you're waiting for nothing and when you're trying to troubleshoot that becomes frustrating. The other option is the check if the serial started with while (!Serial) { delay(10); }
but then your code doesn't run without a serial connection so it just hangs if you try it off a battery or USB charger block.
Here comes the best of both worlds!
It checks for a serial connection every 10 ms but only for 3 seconds, then it goes on. The commented out line is to print how long it takes for your serial to show up. It was useful to determine 3s was a good number (I landed around 2100 to 2700 ms so 3000 gives me just a bit of padding while still being fairly fast when not plugged to a serial console.
Bonus is the giant ASCII START logo I made so I can easily see where it started when scrolling back up.
You can throw this at the top of your setup()
or even better, make it a function and call it, so you only need to comment out a single line when you go testing it without a computer and save those precious 3 seconds at startup.
Enjoy!
Serial.begin(115200);
unsigned long time_begin = millis();
while (!Serial && (millis() - time_begin) < 3000) {
delay(10);
// Serial.println(millis() - time_begin);
}
delay(10);
Serial.println(" ");
Serial.println(" :::::::: ::::::::::: ::: ::::::::: ::::::::::: ");
Serial.println(" :+: :+: :+: :+: :+: :+: :+: :+: ");
Serial.println(" +:+ +:+ +:+ +:+ +:+ +:+ +:+ ");
Serial.println(" +#++:++#++ +#+ +#++:++#++: +#++:++#: +#+ ");
Serial.println(" +#+ +#+ +#+ +#+ +#+ +#+ +#+ ");
Serial.println(" #+# #+# #+# #+# #+# #+# #+# #+# ");
Serial.println(" ######## ### ### ### ### ### ### ");
Serial.println(" ");
Serial.println(" ");
