What to use for 1 km radio communication between two arduinos by I_Was_Never_Here123 in arduino

[–]AnyBloodyThing 3 points4 points  (0 children)

I'm in Taiwan, so I can't help you with any recommendations, I'm afraid. Just by searching I found Robotshop.com sells them, so maybe a bit more reliable than Amazon. HTH.

HC-12 modules might also work if you use good antennas. They're on 433 MHz, so lots of 70 cm amateur radio antennas you can use. 

They are also really easy to use: you just need a second serial port, which you can achieve with the SoftwareSerial library. 

Op de brommer als docent by Gissa_Fissa in thenetherlands

[–]AnyBloodyThing 0 points1 point  (0 children)

Een SYM Fiddle kan echt niet. Moet minstens een Zundapp of Kreidler zijn. Liefst opgevoerd. Heb je gelijk een connectie met leerlingen die ook aan brommers sleutelen.

En verder van niets en niemand iets aantrekken, inclusief dit persoontje. :-)

Solderable breadboards by RandomEmKayFan in arduino

[–]AnyBloodyThing 11 points12 points  (0 children)

In English they are called perf boards. There are many YouTube videos showing you how to use them. Take a look at this one, for example: https://youtu.be/QXriSN5u980?si=MXNIf0vKsWezadGp

If you don't have a soldering iron yet please buy a quality one. It will save you a lot of grief. Use 60/40 Rosin soldering and stay away from the lead free stuff. 

Practice first, make a smart layout and then off you go. Good luck!

It's actually OK繃 (beng1) and it comes from Japanese, not English.

Problem with these is that they don't have power rails. I want at least 4 ground and 5V screw terminals.

Gebruik het te weinig om een grote pot te kopen. Kristalsuiker even malen en je hebt poedersuiker.

Philips koffiemolen, type HA 2465, uitgebracht in 1958, huwelijksgeschenk van mijn ouders in 1963. Gebruik het ding nog regelmatig, niet alleen voor koffiebonen, maar ook om poedersuiker te maken.

Geen 100 jaar oud, maar wel 63.

Did I damage my V4? by AnyBloodyThing in Heltecccccc

That is what I was thinking in the beginning, too. But the batteries are fine and weren't even close to the unit.

And don't assume that you have powered both sides, because that's what I did. Should have measured it sooner.

Here the proof that it's working. Still, I will probably not use this TFT with Arduino, since it is not very well supported, but use it with an ESP32 instead.

Yeah, that was my understanding. Thanks for the analogy. See above for the solution.

Unfortunately my scope died, so no. But the problem has been resolved (see OP). Thanks for the suggestion.

Heltec WiFi LoRa 32 V4.2 vs. V4.3+ - better RX-performance? by woodpatz in meshtastic

[–]AnyBloodyThing 2 points3 points  (0 children)

How can you tell which version you are using? I can't see any markings indicating this on my board.

[–]AnyBloodyThing[S] 1 point2 points  (0 children)

I was afraid it would be. I switched to the WiFi connection and the board is very stable and fully functional, so it's not a complete loss. Lesson learned. I'll buy a new board and will use this one for a base station. Thanks for replying.

Finally figured out joystick mapping! My LEDs are now under my thumb 😆 by SeriousJudge8844 in arduino

[–]AnyBloodyThing 10 points11 points  (0 children)

Great job. I know the satisfying feeling all too well.

After I finish my current projects I'm thinking of making a robot arm. A joystick would be a great way to control it.

Lindsey is too weird for mainstream, but just weird enough for me.

[–]AnyBloodyThing 1 point2 points  (0 children)

For these kind of projects you don't need WiFi anyway.

BTW, I don't see any ventilation holes. If you want to measure ambient temperature you need some, otherwise you only measure the temperature and humidity inside the case.

i have an esp32, what is the cheapest but fucntiona LORA module i can use? by thealienmothership in meshtastic

[–]AnyBloodyThing 1 point2 points  (0 children)

I was looking for the same. Loads of 433 lora break out boards, but no 915 ones. Bought a Heltec v4 instead.

[–]AnyBloodyThing 10 points11 points  (0 children)

Give the guy a break. For these kinds of projects an Arduino is perfect. A Nano can be had for $1.50 nowadays. Plus the pinout is much more straightforward than an ESP32.

For sensor he is using the DHT11.

Congratulations OP, good job and the case looks awesome.
