Boek: Mastering the Arduino Uno R4

Gebaseerd op de voordelige 8-bits ATmega328P-processor, is het Arduino Uno R3-bord waarschijnlijk het populairste lid van de Arduino-familie geworden, en dit werkpaard is al vele jaren bij ons. Elf jaar later werd de langverwachte opvolger, de Arduino Uno R4, uitgebracht. Deze is gebouwd rond een 48 MHz, 32-bits Arm Cortex-M4 microcontroller en biedt aanzienlijk uitgebreider SRAM- en Flash-geheugen. Daarnaast zijn een nauwkeurigere ADC en een nieuwe DAC aan het ontwerp toegevoegd. Het Uno R4-bord ondersteunt ook de CAN-bus met een interface.

Er zijn twee versies van het bord beschikbaar: Uno R4 Minima en Uno R4 WiFi. Dit boek gaat over het gebruik van deze nieuwe borden om veel verschillende en interessante projecten te ontwikkelen met slechts een handvol onderdelen en externe modules.

Alle projecten die in het boek worden beschreven, zijn volledig getest op de Uno R4 Minima of de Uno R4 WiFi-kaart, afhankelijk van het type. De projectonderwerpen omvatten het uitlezen, besturen en aansturen van veel componenten en modules in de kit, evenals op de betreffende Uno R4-kaart, waaronder...

  • LED's
  • Weergaven met 7 segmenten (met timer-onderbrekingen)
  • LCD's
  • Sensoren
  • RFID-lezer
  • 4×4 toetsenbord
  • Realtime klok (RTC)
  • Joystick
  • 8×8 LED-matrix
  • Motoren
  • DAC (digitaal-naar-analoog-omzetter)
  • LED-matrix
  • WiFi-connectiviteit
  • Seriële UART
  • CAN-bus
  • Infraroodcontroller en ontvanger
  • Simulatoren

... dit alles op creatieve en educatieve wijze, waarbij de werking van het project en de bijbehorende software tot in detail worden uitgelegd.


Arduino Uno R4 WiFi

De Arduino Uno R4 wordt aangedreven door de Renesas RA4M1 32-bits ARM Cortex-M4-processor, wat zorgt voor een aanzienlijke verbetering in rekenkracht, geheugen en functionaliteit. De wifi-versie wordt geleverd met een ESP32-S3 wifi-module naast de RA4M1, waardoor de creatieve mogelijkheden voor makers en ingenieurs worden uitgebreid.

De Arduino Uno R4 werkt op 48 MHz, een verdrievoudiging ten opzichte van de populaire Uno R3. Daarnaast is het SRAM-geheugen geüpgraded van 2 kB naar 32 kB en het flashgeheugen van 32 kB naar 256 kB om complexere projecten te ondersteunen. Naar aanleiding van feedback van de community is de USB-poort nu een USB-C-poort en is de maximale voedingsspanning verhoogd naar 24 V met een verbeterd thermisch ontwerp. Het bord bevat een CAN-bus en een SPI-poort, waardoor gebruikers minder bedrading nodig hebben en parallelle taken kunnen uitvoeren door meerdere shields aan te sluiten. Er is ook een 12-bits analoge DAC op het bord aanwezig.

At this rate, I'm leaving this to my kids in my will
Size: 19 Ounce (Pack of 1)
Ten months in and I have barely made a dent in this tub. I am genuinely starting to consider my options — mixing it into smoothies, using it as a cooking fat, applying it to every surface in the house. Something has to be done because at the current rate of consumption this container will outlive me. In all seriousness, the value proposition here is almost absurd. CeraVe Moisturizing Cream is a legitimately great product — dermatologist recommended, ceramides, hyaluronic acid, fragrance free, non-comedogenic, works on face and body, gentle enough for sensitive skin. It does everything a moisturizer should do without irritating your skin or smelling like you bathed in a candle. The 19oz tub is the right call if you actually plan to use moisturizer regularly. A little goes a long way, which is both the best and most frustrating thing about it. Best because you're getting incredible value per ounce. Frustrating because you will be looking at this same tub for the foreseeable future with no end in sight. Great product, generational quantity. Buy it once, pass it down. One star deducted because I now have to figure out what to do with the remaining 18.5 ounces.

It's not glamorous but it works wonders - even while I am on Accutane!
Size: 19 Ounce (Pack of 1)
This is the best, most luxurious lotion I have ever used. And the only lotion that I can even stand to be on my skin. I started Accutane (for acne) last year and was told that my skin would dry out horribly and that I needed to find a good moisturizer to limit the peeling and cracking that I would inevitably experience. Prior to the medicine my skin was oily and very acne prone and every lotion that I had tried either made me feel like I was wearing a latex suit or broke me out horribly. After doing some research I read that this was a great solution and figured I would give it a try. I started it out right away to try to avoid getting dry and was shocked at how well it worked. Even at the beginning when I was still oily this lotion never felt too heavy. Now don't get me wrong-it goes on like frosting and initially feels like a lot-but within minutes it soaks in and leaves your skin feeling like a little kids (not the sticky kind of little kid though-the good clean little kids with undamaged skin). It will last for days too. No need to reapply because it has soaked in to your skin and doesn't just sit on the surface. My skin has never been this soft. And here I am, nearly 9 months in to my Accutane medication regimen and I am not flaking or peeling. In fact, my skin has never looked better or more healthy. My doctors are shocked at how my skin has stayed moisturized because nearly everyone peels. And it doesn't break you out which is obviously something super important. Now, could I be an anomoly? Maybe, but I don't think so. I honestly think this lotion is Just. That. Good! The price isn't bad either!

Great for dry skin and the whole family
Size: 19 Ounce (Pack of 1)
We use this at home for everyone, including the kids, and it works really well. We all have pretty dry skin, and this cream keeps it hydrated for hours. I apply it after showering and it leaves the skin soft without feeling greasy. It has no strong scent, doesn’t irritate, and hasn’t caused any breakouts. I also feel comfortable using it on my kids because it’s gentle and effective. The jar lasts a long time since a little goes a long way. I would definitely buy it again.

Dry Skin Miracle!
Size: 8 Ounce
I have very dry skin, and around my chin and nose, it flakes and turns red, exposing my inner layer of skin due to severe dryness. I could never seem to hydrate it or get rid of the flakiness. I thought it was just my skin at this point, and I could do nothing to solve it. Now, I've never considered using Cerave; I've always heard negative things about it. However, I've never been a makeup person until now, when I want to try to elevate my look (not to mention I'm always in pain from a lack of hydration). The problem is, my skin is so dry that it cracks the makeup, preventing it from setting well on my face. Another problem is that around my nostrils, the flakiness looks like boogers, nasty. It's incredibly annoying. So I did a little research, and now I'm here. LET ME TELL YOU! This cream is amazing! I love how thick it is, and how a little goes a long way! My face, for the first time in my short life, is not dry! It's not buttery smooth, as in your hand won't glide against my face, but it won't feel the flakiness and roughness of my skin—and that's a game changer! I'm genuinely obsessed with randomly rubbing my face to feel the almost barrier of hydration, especially around my nostrils! I cannot explain the level of amazement I felt when I touched my nostril area to feel practically smooth skin. I felt as if it were a miracle. I've only used it for a week now, keep in mind, and this is how I feel. PLEASE BUY THIS IF YOU'RE LIKE ME! I'M SO HAPPY WITH THIS PURCHASE, AND IT'S WORTH ALL MY MONEY 🙏

Quietly effective leave-on exfoliant that smooths pores
Size: 1 Fl Oz
I bought this to tackle clogged pores and the occasional blackhead and to even out my skin without scrubbing harshly. I wanted a gentle option I could use daily without irritation, especially on the more sensitive areas around the nose and cheeks. In everyday use, I cleanse, pat dry, then apply a few drops and let it sink in. It dries down quickly, leaves no fragrance, and doesn’t feel sticky or harsh. It’s a liquid leave-on with 2% salicylic acid that helps unclog pores while smoothing dead skin, and I can follow with moisturizer and sunscreen without any trouble. What stood out the most is how it clears inside the pore and smooths texture over time. After several weeks I notice my skin looks more even and the fine lines around my eyes and mouth appear a touch softer. It feels hydrating while still doing the exfoliating job, which is nice to experience without extra dryness. A small note: there can be a brief, mild tingling if my skin is dry or I use too much at once, so I started with a smaller amount and every other day for a week. Sunscreen is still important during the day. Overall, it fits my routine well and I would rate it five stars.
