Arduino Under The Hood @ArduinoHood

Let's start the new year with a 50% off voucher for one of the best courses for #Arduino and #Atmegas: udemy.com/course/arduino… #Udemy #Avr #embeddedsystems

Many #Arduino communication projects are interesting: E.g. a WiFi module has a 32bit CPU running at more than 80MHz (#ESP8266) vastly outperforming the main CPU e.g. #ATmega328P with 8bit and 16MHz. In this case, consider porting your program to run on the WiFi module instead.

In 1994 Timex DataLink was one of the first smartwatches. It could read data (calendar, alarms, etc) directly from the screen using an optical sensor. famiclone uses an #Arduino, #Win95, and a TTL adapter to sync his watch again: github.com/famiclone6502/…

Plywood board instead of #breadboard looks a lot better for the #attiny. instructables.com/ATtiny85-Snake…

Finally, a purpose of those "half holes" on the boards. They can be used by #FlexyPins, an interesting plug and play solution to quickly test or flash new devices: solder.party/docs/flexypin/…

The new @arduino Uno Mini (Limited Edition) celebrating 10 million Arduino boards, has arrived! It is about a quarter in size, has a USB-C connector, golden traces, and - as usual - a blinking orange LED (green is the power LED). #arduino #arduinouno #embeddedsystems

A maker board has never been this desirable. 😍 The #Arduino #UNOMini Limited Edition is a miniature version of the UNO you know and love, in a stunning new package, signed by the founders, in limited quantity for collectors and Arduino aficionados... 🖊️ arduino.to/uno-mini-le

The BLACK FRIDAY WEEK has started. Use the promo code and start learning! udemy.com/course/arduino… Code valid till 11/27/2021 (12:00pm PST) #embeddedsystems #learning #technology #arduino #avr #blackfridayoffer #blackfriday #blackfridaydeals

Don't overlook the powerful, beautiful #ArduinoDue for your next project, especially since it's part of our #BlackFriday sale ✌️store.arduino.cc/collections/sp… Just take a look at some of the amazing things it can do 😮 create.arduino.cc/projecthub?by=…

Before floppy discs were a thing, we stored data, programs, and games on cassette tapes ("Press play to load..."). It made similar sounds to an analog modem. If you want to go back to cassette tapes, here is a solution: zeninstruments.blogspot.com/2021/10/manche…

For Arduino projects that require displays, an optimized PNG library opens the door to show images on the display. The library decodes the PNG and forwards it to the display line by line: bitbanksoftware.blogspot.com/2021/05/an-emb…

C or C++ are not the only language for the ATmega/Arduino. Another language designed especially for embedded systems is Forth (forth.com/forth/). Athanasios was able to bring it up for the ATmega. Have a look at thanassis.space/miniforth.html

Flash optimization for Arduinos. Many old Arduinos use a 2 KB bootloader. Replace that one with the Optiboot bootloader and reclaim 1.5 KB (5% of total flash memory). Here is an example using 2 Arduino Nano (1 as ISP, 1 as target). youtube.com/watch?v=-MynHA…

Have you finished your final #exams but you don't know what to do during the upcoming #weekend in #lockdown? Learn what's going on under the hood of #Arduino. Special offer for a limited time. Approx 20 hrs of lectures for only €9.99 instead of €109.99: udemy.com/course/arduino…

My new @udemy course is #online. It is about how to schedule multiple #tasks to be completed by the #Arduino or #AVR architecture conveniently, efficiently and seemingly simultaneously. udemy.com/course/arduino… PS: If you wait for a few days, the course will be offered for free!

With the addition of a MOSFET and some tweaks to the program code, an Arduino Uno can log every two seconds for a year on a 2,400mAh battery. hackster.io/news/researche…
