Wemos D1 uno
ada yang pernah punya wemos d1 uno ? board dengan isian ESP tapi bentuk badannya uno. kompatinle ngga ndengan shiled uno ? sepertinya perlu ada penyesuaikan tegangan io.. karena wemos bekerja pada tegangan 3V takutnya njebluk kena tegangan 5V dari output Shiled uno nya.. lha trus? klo ga paham jangan diteruskan mending ganti buat wemos D1 Mini board yang sudah pasti bekerja di 3V .. meminimalisir kesalahan akbikat beda tegangan. ibarat sepeda listrik tagangan 24V dan 48V pasti beda . klo pun harus bersatu dikawinkan salah satu harus pindah tegangan. atau di diubah ditambahin interface konvesi logika IO nya ayau modul lain sejenis. ribet kan?
Tahun 2024 bikin robot apa enajnya
udah lama ngga posting tentang robotik disini. bagaiman kabarnya mg90 ? sudah dipamnasi blum.. saatnya mg90 berolahraga. Loh dimana sekrng ? udah di bungkus kardus masuk gudang. hmm.. Semester genap ini mustinya di buka kembali untuk melanjutkan bikin robot mainan spifer. dan update firmware codingnya. ada yang suday pinya robot spider 4 kaki? dengan motor mg90 sebanyak 8 biji ? silahkan komen disini

2022 berpindah dari arduino atmega328 ke esp2866
saatnya berpindah dari arduino uno nano ataupun promini ke board wemos lolin esp2866 karena harga mereka mahal.. esp2866_12 bisa hanya 20rb saja sedangkan uno dan nano sudah tembus 60rb keatas.. dulu harga atmega328 saja sekitar 30rb an..
mengejar ketinggalan pembelajaran IoT mari kita mempersiapkan ilmu kita untuk menghadapi era Internet di jaman new normal ini
contoh board yang masih menggunakan arduinoIDE untuk lingkungan pemrogramnnya adalah Wemos dan lolin mereka semua berbasis wifi alias menggunakan chip / IC esp2866. diharapkan kalian sudah belajar contoh contoh pemrograman yang ada di example di menu arduinoIDE
Bahan yang dipersiapkan :
Laptop terinstall arduinoIDE dan board Wemos atau Lolin, cari di internet cara menambahkan pilihan board padda ArduinoIDE
sebuah board wemos atau lolin, pada kali kesempatan ini saya menggunakan wemosD1
Tes ujicoba board
pastikan board berfungsi normal dengan mengupload sketchcode blink ke dalam WemosD1
setelah berhasil maka wemodD1 akan berkedip kedip LED nya.
bersambung.

Lusana Elektro Project 40 Smart Alarm with bluetooth
Hello student.. lets study How to controlling switch to turn on and off the fan and lightball. this operate with DC 12V so save enough for teenager to build it. First you must have DC adaptor from AC200Y outlet into DC12V to connect with this device. examine this scheme before make the skecthcode.

Project 2020
Adanya pandemi covid membuat saya mati gaya, tidak menghasilkan project tentang robot ataupun arduino microcontroller
hanya impian yang berlum terlaksana. pengen juga bikin tangan buatan atau kaki robot seperti film Alita 2019.
sambil nyanyi lagunya SIA- I m STOPPABLE
robot spider ku juga sempet terbikin tapi kendala waktu dan kesibukan bekerja ya mangkrak masih tersipan rapi, belum dimaninkan lagi nunggu waktu longgar entah di bulan pertengahan tahun biasanya
penggunaan display untuk wajah, texting out, VGA X monitor di arduino sudah di coba, tinggal menggabungkan codingnya yang lumayan ruwet riweuh mumet bin rumit. ada teman teman yang sudah jadi projectnya dan bisa dishare di mari, kasih tau aku ya..
ada vlog? punya tapi kok jadi malas mendokumentasi sesuai yang aku bikin, mustinya fokus satu project dokuentasi trus jual haaa. masih sibuk kerja kantoran ini nih..punya tokopedia? masih lesu belum jualan lagi mungkin tahun depan mau jualan pcb lagi.
sekian terima kasih

104 pre amp mic modul
Project 104 in Januari 2019 initiated. but until this time, on May I open this project..
sorry early this year i got busy.. so this is may in 2019 lets go "Cuusss...."
i open DIY universal Board from PCBWAY nyamm.. yummy fresh from box.
HOw to order ?
Login with youraccount click order quote. I ussualy do fast fill form just fill dimension with 99 length and width 99mm check box use HASL. color green if you want change into blue red or green. purple is expensive, white and black only for closed hardware. they cannot easy read track on pcb. all white or all black
Best warm greetings in Summer Haze

TFT LCD test
TFT LCD test
Using Adafruit 2.8" TFT Breakout Board Pinout
TFT size is 240x320
Unknown LCD driver chip: 5408
If using the Adafruit 2.8" TFT Arduino shield, the line:
#define USE_ADAFRUIT_SHIELD_PINOUT
should appear in the library header (Adafruit_TFT.h).
If using the breakout board, it should NOT be #defined!
Also if using the breakout, double-check that all wiring
matches the tutorial.

51 arduino io toolbox shield
i need simple shield to demontrate led r g b
i need to see wave form... use a0 as input signal
void setup() {
// initialize the serial communication:
Serial.begin(9600);
}
void loop() {
// send the value of analog input 0:
Serial.println(analogRead(A0));
// wait a bit for the analog-to-digital converter
// to stabilize after the last reading:
delay(2);
}

Project 43 audio vu meter menggunakan ic 74HC595
Desainnya sederhana saja menggunakan IC 74HC595 shiftregister untuk menyimpan data hasil pembacaan analog to digital conveter yang ada pada ATMEGA328. PCB ini di cetak di pcbway.com. Awalnya aku memesan file desain PCB (di upload) dalam bentuk gerber sekitar tanggal 25 September 2017. Baru bisa dibayar akhir tahun nunggu voucher kupon cetak gratis. Setelah di cetak di PCBWAY lalu di kirim ke aku berikut video unboxingnya

38 Simple Clock use sevseg.h print circuit board on PCBway
here the share project about simple clock : scheme grab from Mr. Rokhmad sragen...
and here the layout i retrace from original one. turn into double layer n make top down .
bug : the light no stable.. different each other.. need ressisor 220ohm between board wire a b c d e f g
after click share n sell you got preview..

40clocxdotmatrix My Purchase experience in November 2017
Order ID: G101596 contents :
32minsysdotmatrix
36postalavr
38simpleclocx
41proshield
Universal PCB
The reason packing all off them into one delivery is more cheap on freight/shipping charge. I dont care about the time. take more time to wait all of my project produced but its okay.. i just sit relax while create new design. I just im4jine build runnintext 24x8 in radial view.. cool isn it.?
About The price,. i Always use Special promo Price.. limited in size but its the challenge to create PCB simple and small. still wanna make order again next month. November Desember liitle bit busy endyear report.
so this time to charity.. i spread this PCB into several friends : such as ekobayu Mr. Rokhmad. Mr.Occi, Mr Heryan umm.. do you wanna taste this PCB board? visit pcbway.com meet my project in section shared project outthere...
i also help several friends to make purchase order at PCBway. the main problem is language.. so i help him to make an order PCB. Greetings from all friends in Indonesia..

it c4lled minimum system.. mini c4se... 99x99mm... p4st project ( esr ) i use pocxet sise.. only 70x90mm. but i dont desi9n booxc4se.. (20x20) bec4use too expensive.. PCB m4nf4cture.
I optimise d cost .. by reduce ticnesss . I use 1 mm board ussuly i use 1.6mm . it can reduce weight n delivery cost. see d picture :
