ATMEGA328P-PU: The Little Prince of Microcontrollers in Circuits & Stars

A Meeting in the Desert of Circuits

The desert stretched endlessly, its sands glowing like gold under the sun. I was tracing the dunes, heading toward a distant oasis, when I spotted a glint in the sand—a small, rectangular shape, no bigger than a ladybug.

“You’re… very small,” I said, kneeling. “And you’re a child who talks to microcontrollers,” it replied, voice soft as the wind. “But some keepers of light are smallest when they’re strongest. Ask the fox.”

It was an ATMEGA328P-PU—the heart of Arduino Uno, but to me, it felt like a secret. Let me tell you its story.

1. What Is the ATMEGA328P-PU? (A Keeper of Code, Not Just Silicon)

This was no ordinary chip. It was a ATMEGA328P-PU, an 8-bit AVR microcontroller in a 28-pin DIP suit—smaller than a baobab seed, but tough as the roots of the rose’s planet. Here’s its secret:

Clock Speed: 16-20MHz (overclockable to 24MHz for daredevils). Faster than the fox darting across the dunes.

Memory: 32KB Flash (stores code), 2KB SRAM (variables), 1KB EEPROM (your debugging tears). Like a Pensieve for electrons.

I/O Pins: 23 programmable pins (14 digital, 6 analog). Windows to the world—like the portholes on a spaceship.

Fun Fact: Engineers call it the “Cockroach of MCUs.” Survives power surges, cosmic rays, and your “hold my beer” coding experiments. Even the baobabs can’t crush it.

“Why so quiet?” I asked. “Keepers don’t shout,” it said. “They just keep.”

2. ATMEGA328P-PU & Its Siblings: Stars in the Same Sky

In the desert of microcontrollers, ATMEGA328P-PU has siblings—some older, some louder, but none quite like it:

ATMEGA328-PU: An older star. Higher power draw, like a planet that burns too bright. Avoid—like flip phones in 2025.

ATMEGA328PB-PU: A louder sibling. Extra peripherals (UART, timers), but bulkier. For complex projects, like a planet with too many volcanoes.

ATMEGA328P-PU: The steady one. Lower power (1.8V-5.5V), optimized code. Ideal for battery-powered projects—like a rose that blooms in the desert.

Roast Alert: ATMEGA328-PU (grumbling): “I’m vintage!” ATMEGA328P-PU (calm, like the fox): “I’m in NASA prototypes. You’re in a landfill. Bye.”

3. Why the Fox (and Engineers) Choose It

ATMEGA328P-PU isn’t flashy. It’s the kind of friend who shows up, fixes your code, and leaves without fanfare. Here’s why:

Cost: $3/unit—cheaper than a morning espresso (and way more useful). Even the rose, who’s picky, approves.

Simplicity: No Wi-Fi tantrums or driver hell (looking at you, ESP32). Like a well-tended garden—no weeds.

Community Support: 10k+ Arduino tutorials. Google is your co-pilot, and the fox is your guide.

Real-World Flex:

Mars Rover Prototypes: Runs in -40°C labs (tested by NASA JPL). Even cosmic frost can’t stop it.

DIY COVID Ventilators: 2020’s MacGyver hero (MIT Open-Source Project). Saved lives, one byte at a time.

“Why not be bigger?” I asked. “Big things break,” it said. “Tiny things fit. In garage labs. In Mars rovers. In portable ECGs.”

4. Programming the Little Prince: A Dance with Code

Want to wake the ATMEGA328P-PU? It’s like taming a fox—gentle, patient, and rewarding.

Option 1: Arduino IDE (The Friendly Path)

Connect via USB-to-Serial (e.g., CH340G). Pray the drivers install (sometimes they don’t—blame AliExpress).

Select Board: Arduino Uno (even if you’re using a breadboard).

Upload Code: Watch the LED blink, like a star winking hello.

Option 2: Bare-Metal with AVRDUDE (The Adventurer’s Path)

Command: avrdude -c usbasp -p m328p -U flash:w:your_code.hex

Pro Tip: If smoke appears, take a breath. The fox says, “It’s not your fault—sometimes stars misbehave.”

5. Burning the Bootloader: Tending the Rose

Burning a bootloader is like planting a rose—delicate, but necessary.

Tools Needed:

Programmer: USBasp, Arduino as ISP, or a sacrificial Uno (no tears, it’ll forgive you).

Software: Arduino IDE or AVRDUDE (the gardener’s tools).

Steps:

Wire It Up: Connect MOSI, MISO, SCK, RESET, GND, VCC. Triple-check—no one likes a fried rose.

Arduino IDE: Tools > Programmer > USBasp (or your tool).

Burn: Tools > Burn Bootloader. Wait for the magic (or error messages—they’re just the rose’s thorns).

First ATTINY85 project!

(warning: video has actual flashing LED lights)

[ Video ID: A breadboard with a Blue LED on top of an 8-pin DIP Integrated Circuit on it. The Blue LED is flashing rapidly. There are other components on the breadboard in the background. End ID ]

Last week I bought some ATTINY85 Microprocessors to experiment and work with :) With my W65C02 project on hold until I can afford an oscilliscope, and my Radio project delayed because I can’t quite figure out how to reverse engineer the 8 pins on the volume knob, I wanted something else to work with. I’ve been wanting to mess with Atmel microprocessors (Arduino Uno runs on an Atmel ATMEGA328), and now’s a good chance!

I’m jumping straight to assembly with the ATTINY85; I don’t know any C/C++ code, and also I’m familiar with other processor Assembly languages, so I might as well. And other than different names for functions, it’s been pretty easy so far! Something I’m not used to is that this processor, despite being pathetically tiny, has 32 registers; I’m used to working with 8 Max.

Anyways, for the code explanation: When the processor first starts, it turns on PINB0, which is physical pin 5 on the processor. Then, after counting to 256 256 times, it turns off PINB0 for another 256^256 counts. I’m away from home while writing this, so my notes arn’t here, but if I remember correctly it came up to 200k microseconds? That adds up to about 400 nano seconds per on/off cycle, or 2.5 flashes per second. I can add in another loop to make it last longer, but before I do that I’d like to look about to see if there’s a smarter way to tackle this.

My next step after this, is to figure out how to get this processor to read digital inputs: My next project is to finally do something with my box of telephone rotary dials. I already have one spec’ed out for breadboard testing. I would LOVE to show it, but Tumblr has a One Video Per Post limit :(

Arduino Nano Board R3 with CH340 chip

Based on the Arduino platform, the Nano R3 Board CH340 Chip without USB Cable does all the functions of the Uno, but has a smaller footprint.

Using Nano CH340 Soldered Board R3 Chip without USB cable is essential for your small project where you don’t need many pins, but the small size is very important to make it look nice.

In comparison to older versions of Arduino Nano with FTDI USB-Serial Chip, the Nano uses a low-cost USB-Serial Chip.

With the ATmega328 (Arduino Nano R3), the Nano is small, complete, and breadboard-friendly. It has more or less the same functionality as the Arduino Uno but in a different package. In addition to lacking a DC power jack, it uses a Mini-B USB cable instead of a standard one.

This device can be powered by a mini-USB cable, a 6-20V unregulated external power supply (pin 30), or a 5V regulated external power supply (pin 27).

Six PWM I/O are included from a total of 14 digital I/O, eight analog inputs, 16Mhz clock speed, and 32kB flash memory.

Please note:

The CH340 chip might not work directly with some PCs/laptops. You will need some drivers for the CH340 chip.

Arduino nano features :

TTL level serial transceiver ports (RX / TX)

Atmel Atmega328P-AU MCU used

It has a bootloader installed

Supports USB download and power supply

Provides support for external DC power supplies of 5V and 12V

This was a masterclass in product-design.

It's viscerally engaging, and makes you reflect. How did they make this? The ATmega328 has 32 KB of memory, which I'm guessing was the brain of this ai-toy, but still! My theory is it would try to first understand if it was a person, place, or thing, and then go from there, but still! Imagine programming "Bosnia" into this thing, just for it to be written off as a "childish"-toy.

I'd be looking for my Nobel Peace Price, or whatever they give scientists (peace.?). . IDK, this thing had a pretty high success rate! I read one account where some 10-year old was thinking of "butthole" on a road-trip, and the machine guessed "sphincter" and then when they looked it up in the dictionary, they were shocked.

It's fine though, I understand why "programming" isn't taught in high-school. It's much better to get kids to look back at history instead of towards a world that they will soon inhabit. Nothing gets a kid ready to take on the world like reading about the "War of 1812!" It's not like they grow up with calculators in their pocket, either. It's much more important that they learn Spanish, because it's not like there's a translator in their pocket, either!!!
