arduino-cli VS chainlink

This isn't a USB error. It seems to be the result of the compiler not finding some sort of java signature file(?). Looks like it's a Mac thing and started with IDE 2.0.1. Maybe update IDE? https://github.com/arduino/arduino-cli/issues/1970

The Arduino community has been buzzing with excitement over the recent release of the new version of the Arduino Command Line Interface (CLI), version 0.30.0. This new version offers several exciting new features and improvements that are sure to delight Arduino enthusiasts and makers everywhere.

There's a vscode extension you can install that uses the arduino backend to compile and upload new sketches. You'll have to have the IDE/CLI already installed. If you want to avoid the IDE entirely I'd recommend the CLI available on github here and the instructions for the vscode extension can be found on circuitstate here. Good luck!

I think you're looking for the underlying arduino-cli tool, rather than calling against the IDE directly.

Yep! Or their CLI version: https://github.com/arduino/arduino-cli

If you're going to program the Uno away from the Arduino IDE, they have a nice CLI support for it, too. https://github.com/arduino/arduino-cli

I never tried it on a Pi Zero, but did you download the ARMv6 version?

In August 2018, Arduino announced its new open source command line tool (arduino-cli), which can be used as a replacement of the IDE to program the boards from a shell.[22]

Would the Arduino-CLI work for you? https://arduino.github.io/arduino-cli/0.20/ and https://github.com/arduino/arduino-cli

Chainlink has announced the launch of its Payment Abstraction system, a cross-chain payment solution designed to reduce payment friction and simplify fee conversion for Chainlink services.

Why employers love it: Interoperability is a huge focus in blockchain development right now. Companies like Chainlink and newer L2 solutions are actively hiring developers with cross-chain experience.

On the final day, our first post-conference event hosted in collaboration with our partners Chainlink and Sygnum Bank saw attendees from TOKEN2049 join members from our ecosystem and beyond for a night of drinks, food, and networking - exploring RWA tokenization, decentralized finance, fintech, and more - featuring a talk from HBAR Foundation Head of Fintech & Payments Sabrina Tachdjian.

Chainlink (LINK) – The Blockchain Oracle Giant

Chainlink allows smart contract developers to receive a wide variety of off-chain data, with the most commonly used features being receiving off-chain randomness and off-chain pricing data. Integrating your smart contracts with Chainlink provides a unique set of potential security vulnerabilities that attackers can exploit; here are the common vulnerabilities that smart contract developers & auditors need to look out for.

In some way, I'd also put Chainlink in that category since they allow to access open world data on-chain and making dapps more relevant as a result.

Smart contracts have revolutionized various industries by enabling the automation of agreements and transactions in a secure and decentralized manner. However, for smart contracts to reach their full potential, they need access to real-world data and external systems. This is where Chainlink comes into play.

I would suggest the use of an oracle like chainlink. Link: https://chain.link - I don't know exactly what your specific requirements are since I cannot review your code but a thirdparty oracle sounds like it could offer you at least some direction.

🥁 Introducing Co:OPERATE @ EthCC by Celo with Co:HOST Chainlink!

Etherisc has built a platform (Generic Insurance Framework) for decentralized insurance applications. We use blockchain technology to help make the purchase and sale of insurance more efficient, enable lower operational costs, provide greater transparency into the industry and democratize access to reinsurance. We’ve been around since 2016, have many high-profile collaborators (including Chainlink) and are proud of the innovative applications of the parametric insurance products built on our platform, including travel delay, crop and carbon credit protection.
