For problems with Arduino itself, NOT your project

Standalone or alternative microcontrollers, in-system programming, bootloaders, etc.

Using Arduino to interface SD cards, floppy drives, harddrives, EEPROMs, etc

I2C, SPI, XBee, GPS, etc.

sensors, analog inputs, filtering, etc.

Controlling big heavy things that move, need high voltages, high current, or both

LCDs, OLEDs, PAL, NTSC, etc.

Understanding the language, error messages, etc.

Problems related to uploading your compiled sketches

Tutorials for new people on the forum.

Solutions for basic circuits. DC converters, inverters, amplifiers, etc

Discuss getting your PCB or product manufactured or assembled. Home brew PCB's, Pick & Place machines, reflow etc.

A community section to discuss Open Source Hardware (OSHW) projects or anything OSHW related. If the project is not licensed under the OSHW scheme, please put it in the regular Projects & Technical section.

Power related discussions, Renewable Energy, energy storage, Electric Vehicles etc.

RF, Microwave, and Ham Radio designs, projects, and discussions.

Everything programmable logic related. FPGA's, PLD's, VHDL, Verilog etc

Show us your projects and other stuff you've made or working on. Tell us about designs or ideas, ask technical questions, and share technical information. This is the big catch-all thread for anything electronic.

General discussions about microcontroller hardware or software. Use the Embedded Computer section for single board computers like Raspberry Pi etc

Ask for repair help or describe how to repair equipment

Some details and what you have already done to find the answer. Breif "How does X work" questions are not proper forum etiquette. Assignment questions are ok, but show existing work.

This is where everyone hangs out and rants and chats about whatever electronics topics that don't fit into the other more specific categories on this forum. Occasional off-topic stuff is ok, but generally we like to keep it electronics related.

Looking for contract or regular work? Post your work wanted ad here listing your skills and what you have to offer. Resumes attachments (PDF) are allowed if you want to make them public. Companies NOT allowed.

List your electronics related stuff for sale, or link to others. Wanted ads go here too. Only dealers who are valued contributors to the forum community are welcome to post here.

An industry jobs board. Post your job ad here. Commercial companies are welcome provided they don't spam and run, you must stick around & contribute. No HR droids or recruitment companies.

PC's, Macs, Tablets, phone thingoes etc

Vintage Computers and related projects

Cloud Computing, Edge computing, Internet Of Things

Everything networking related. Wired and wireless (Wifi, Bluetooth, LoRaWan, and everything else)

Everything computer security related

Everything programming related

Everything embedded computer related. Single board computers like the Raspberry Pi, BeagleBoard etc Hardware and Software.

Anything specific to the Open Source packages KiCad & gEDA

If it doesn't fit into the other categories, put it here. Simulation, general layout, library, footprint, and design questions etc

A user forum for Labcenter Proteus PCB EDA package

Altium Circuit Studio

Anything specific to the Altium Designer package

Anything specific to the DesignSpark PCB package

Anything specific to the Eagle PCB design package
