Hello, today I will show you the breadboard diagram of the previous circuit posted.
I used a 74HC595 shift register in order to turn on one LED at a time, sequentially. ⚡
I noticed is a great device for that purpose!

Update: the purpose of my previous page was to build my own synthesizer.. I had a lot of time for that but I never started. Nowadays I have less time but I've done more progress than in the past 😂

This is a shift register simply used to turn on LEDs one at a time!
Soon I'll show you the electrical diagram. ⚡

↪️ Day 32 of sharing my content from my old IG page
Update: another good project interfacing Arduino and external components, stay tuned for the breadboard design!
Further I'm continuing my project for a MIDI interface through Teensy, I'll show you something more soon 😉

In order to read more buttons with only one input, you can use an analog input connecting buttons in a resistive divider.

Update: a tribute to Kavinsky who recently passed away (background music).
Anyway I hope you're doing well during this hot summer 🌞
I'm on a new project with a Teensy 2.0, I'll share some stuff with you soon!

If you want to connect a button without using the internal pull-up resistor you can connect a 10kohm resistor between the button and ground (so it's pull-down).
Then you can set the code in order to control the LED. ⚡

Update: don't stop when you make it work. Try others variants of the same schematic topology and learn 🙌

If you want to control two LEDs with one wire of , you can use this solution where with a LED on, the other one is off (and viceversa).

↪️ Day 29 of sharing my content from my old IG page
Update: before saying it is a basic circuit, explain in a comment what it does! 😁
This is a practical project for beginners, I hope you like it 🙌

New diy projects are coming back! 😍

↪️ Day 28 of sharing my content from my old IG page
Update: Arduino Uno must remain as an evergreen for makers. Students, hobbyists and makers who want to learn programming and electronics shouldn't start with the Arduino Uno Q, it is too far from learning a microcontroller! 🙌
I see the Arduino Uno Q as a great way to go deeper once you already have a solid foundation. New tools aren’t something to demonize; they’re opportunities to grow and explore further!! 🔥

Another day studying for an exam 📖😵

↪️ Day 27 of sharing my content from my old IG page
Update: I slowed down the rate of posting on my Instagram page, that's because it's difficult for me to maintain the constant capability of use this social media, but I'm happy to share with you some of my memories 🙌

Today I'm back to the normal routine. 📓
The next exam is about digital systems. ⚡

↪️ Day 26 of sharing my content from my old IG page
Update: do you remember quantisation?
The Lloyd-Max quantizer (LMQ) is a quantization function that performs minimum mean squared error quantization.
Suppose we want to find the best way to quantize a set of (continuous-valued) data to n discrete levels. If the n levels are known (let’s say they are values t1 through tn), then the decision boundaries are at the midpoint between the values.

I want to show you the gift that my girlfriend has gave to me😍 for Christmas! 🎄
This is a manual of .. I'm excited to read it!

↪️ Day 25 of sharing my content from my old IG page
Update: I found this book pretty interesting, but I think the best book from this author is "Arduino - Trucchi e segreti. 120 idee per risolvere ogni problema" 🙌
What's your favourite Arduino book? 🧐

Turn the volume on 🔊

I really love this little synth by . 🎹😍
I bought this some years ago and sometimes I like to play it. ❤️

↪️ Day 24 of sharing my content from my old IG page
Update: I enjoyed the time spent with the Korg Monotton, however I think it is expensive for what it offers. I recently sold it because I wasn't using it 😓
Do you ever used it?
