mobil 18ribu menjadi mobil HIGH CLASS

awal mula bikin mobil ini hanya sebuah ke isengan belaka. padahal mobil 18rb ini belinya kemarin sore di toko mainan dekat rumah.

awal mobil datang senang sekali, tapi lama-kelamaan bosan juga. pdahal baru 1 hari.

akhirnya saya punya ide. gimana caranya supaya mobil ini sangat tertarik meskipun harganya 18rb.

mari kumpulkan komponen pendukungnya.

1. mikrokontroller nodemcu (50rb)

2. shield motor nodemcu (22rb)

3. batre holder isi 2 (10rb)

4. batre 18650 sebanyak 2 (15rb bekas)

5. motor + gear sebanyak 2 (42rb)

6. kabel secukupnya. (2rb)
estimasi  hasil dari pencarian di toped 141rb

setelah semua terkumpul 

step pertama  bikin project di aplikasi blynk

jangan lupa token yang dikirim ke email di copy ke coding dibawah ini

step kedua bikin koding:

#define BLYNK_PRINT Serial #include  <ESP8266WiFi.h>#include  <BlynkSimpleEsp8266.h>
// You should get Auth Token in the Blynk App. // Go to the Project Settings (nut icon). char auth[] = "your token"; 
// Your WiFi credentials. // Set password to "" for open networks. char ssid[] = "yourname wifi"; char pass[] = "password"; 
int PWMA=5;//Right side int PWMB=4;//Left side int DA=0;//Right reverse int DB=2;//Left reverse 
void setup(){  // Debug console  Serial.begin(9600);  Blynk.begin(auth, ssid, pass);  pinMode(PWMA, OUTPUT);  pinMode(PWMB, OUTPUT);  pinMode(DA, OUTPUT);  pinMode(DB, OUTPUT); } 
void loop(){ Blynk.run();   } 
// Handling Joystick data BLYNK_WRITE(V1){ int x = param[0].asInt(); int y = param[1].asInt();  if(x==-1 && y==-1){             //Backward and Left          digitalWrite(PWMA, LOW);      digitalWrite(DA, LOW);           digitalWrite(PWMB, HIGH);      digitalWrite(DB, HIGH); }else if(x==-1 && y==0){        //Left Turn      digitalWrite(PWMA, 450);      digitalWrite(DA, HIGH);          digitalWrite(PWMB, 450);      digitalWrite(DB, LOW); }else if(x==-1 && y==1){        //Forward and Left          digitalWrite(PWMA, LOW);      digitalWrite(DA, LOW);          digitalWrite(PWMB, HIGH);      digitalWrite(DB, LOW); }else if(x==0 && y==-1){        //Backward          digitalWrite(PWMA, HIGH);      digitalWrite(DA, HIGH);           digitalWrite(PWMB, HIGH);      digitalWrite(DB, HIGH);}else if(x==0 && y==0){        //Stay      digitalWrite(PWMA, LOW);      digitalWrite(DA, LOW);           digitalWrite(PWMB, LOW);      digitalWrite(DB, LOW); }else if(x==0 && y==1){        //Forward      digitalWrite(PWMA, HIGH);      digitalWrite(DA, LOW);          digitalWrite(PWMB, HIGH);      digitalWrite(DB, LOW); }else if(x==1 && y==-1){        //Backward and Right          digitalWrite(PWMA, HIGH);      digitalWrite(DA, HIGH);           digitalWrite(PWMB, LOW);      digitalWrite(DB, LOW); }else if(x==1 && y==0){        //Right turn      digitalWrite(PWMA, 450);      digitalWrite(DA, LOW);           digitalWrite(PWMB, 450);      digitalWrite(DB, HIGH); }else if(x==1 && y==1){        //Forward and Right      digitalWrite(PWMA, HIGH);      digitalWrite(DA, LOW);           digitalWrite(PWMB, LOW);      digitalWrite(DB, LOW); } } 

upload koding tersebut ke nodemcu.

step ketiga rakit motor + batre + shield motor + nodemcu + mobil 18rb an

abaikan motor a2 dan b2... atau bisa juga bikin 4 motor
tapi saya hanya bikin 2 motor aja. karena di gudang SIMOR hanya ada itu.



setelah selesai rakit
