In recent years, has been widely praised for being able to provide developers around the world with the benefits of using its platform and development board to develop digital and interactive projects.
With the help of, you can add instructions to the microcontroller of a board, so that the hardware or software you want to design can perform specific tasks.
That being said, the reason why we made this post may vary depending on the purpose you have in mind. Therefore, Here are some of the most common and simple technologies you can develop with Arduino.
What kind of devices can I create using Arduino and its hardware development boards?
One of The advantages that Arduino offers is its great flexibility to work on any project. This is based, in general, on the development of the platform, which is . In this way, it can be used in the creation of different types of tasks and unique devices.
If you want to know some projects that you can program quickly, take a look below:
wearables
Wearable technology is very well known nowadays. The small size of its devices, which can be worn under or over clothing, and the functions it offers the user are distinctive aspects of this tool. You can create a prosthesis, a bracelet, a watch and any body object you can think of with Arduino. With this portable technology, it is possible to identify which intelligent accessories can be included in the clothing.
One of the differences that a receiver and transmitter of data for the body has with a common device is that the former have exclusive functions, for example, screens, sensors and a processor to manage specific information required by the user. While the rest of the electronic equipment is designed to perform standard functions, no matter what type of operator uses it.
Here is an example of a . For to create a pulse sensor you will need one and an electronic sensor ProtoCentral for oximeter breakage, you must also have cables to make the connections.
Once you have all the elements you must open the Arduino IDE and copy this code:
#include “Protocentral_MAX30100.h” #include MAX30100 sensor; uint8_t data_len=8; uint8_t DataPacketHeader; volatile long IRR,REDD; void setup() { begin(); begin(57600); while(!Serial); begin(pw1600, i50, sr100 ); printRegisters(); } void loop() { readSensor(); IRR=sensor.IR; REDD=sensor.RED; DataPacketHeader = 0x0A; DataPacketHeader = 0xFA; DataPacketHeader = (uint8_t)(data_len); DataPacketHeader = (uint8_t) (data_len>>8); DataPacketHeader = 0x02; DataPacketHeader = REDD; DataPacketHeader = REDD>>8; DataPacketHeader = REDD>>16; DataPacketHeader = REDD>>24; DataPacketHeader = IRR; DataPacketHeader = IRR>>8; DataPacketHeader = IRR>>16; DataPacketHeader = IRR>>24; DataPacketHeader = 0x00; DataPacketHeader = 0x0b; for(int i=0; i<15; i++) // this will be used to transmit the data to the sensor { write(DataPacketHeader); } //Serial.println(sensor.getPartID()); /* Keep in mind: println(REDD,HEX); println(IRR,HEX);*/ delay(10); }
home automation
When we talk about home automation, in general, it refers to the smart home systems. These technologies are widely recognized for their many advantages when it comes to ingeniously automating any part of a house. There are various types of devices that we can use in this environmentone of the most interesting examples and that has helped to fix the respective security problems are those surveillance systems, alarms and anti-theft locks that can be included in the home.
For you to carry out a project without making mistakes, you can create a surveillance camera with motion sensor. When an alert is triggered you will receive a photo on the . You’ll need a connector kit, an Arduino Nano R3 board, a breadboard, a movement sensor and an ESP32 type camera.
The codes that you will have to write are:
/* Example of using an Arduino Nano R3 board for an ESP32 Internet camera Step by Step */ #include #include const char* ssid = mySSID; const char* password = myPASSWORD; const char* server = “howsmyssl.com”; // Server URL const char* root_ca = \ //Enter a certificate for client authentication, you can get them from authorized peer to peer platforms //If you want, you can use x.509 client certificates //const char* test_client_key = ” “; //this is to verify the client //const char* test_client_cert = “”; //authentication of clients WiFiClientSecure client; void setup() { //Initialize serial and wait for port to open: begin(115200); delay(100); print(“Attempting to connect to SSID: “); println(ssid); begin(ssid, password); // attempt to connect to Wifi network: while (WiFi.status() != WL_CONNECTED) { print(“..”); // wait 1 second for re-trying delay(1000); } print(“Connected to “); println(ssid); setCACert(root_ca); //client.setCertificate(test_client_key); //client.setPrivateKey(test_client_cert); println(“\Starting connection to server”); if (!client.connect(server, 443)) { println(“No connection!”); } else { println(“Connected to server successfully!”); // Make a HTTP request: println(“GET https:// “); //enter the host address println(“Host: “); // Host URL println(“Connection OK”); println(); while (client.connected()) { String line = client.readStringUntil(‘\n’); if (line == “\r”) { println(“headers received”); break; } } // if there are incoming bytes available // from the server, read them and print them: while (client.available()) { char c = client.read(); write(c); } stop(); } } void loop() { // do nothing }
robotics
The term robotics is one of the most mentioned, and not only in this field of design, but also internationally. As we well know, this science is used for the production of robots, this is known, for being devices or computers that have the ability to move and perform a specific task. A simple project that you can make with a Mega 2560 board, an HC-SR04 sensor, a cable kit, and an SG90 servo motor is an Arduino animator.
To do this you must enter these programming codes in the IDE environment:
#include #include #include #include //matrix int l; int Cs = 53; int i=0; int x=7; bool Mprint=false; boolok=false; unsigned long time3; Max72xxPanel m1 = Max72xxPanel(Cs, 1, 1); String msg = “Internet Step by Step, Arduino Course”; int w8 = 70; int esp = 1; int ancpal = 5 + esp; bool msgact=false; // Ultrasound int measure; int ultra=15; int echo=14; hard int; int distance; int dist; bool distOk = false; int shots=0; int c5=0; unsigned long time4; // buzzer int push; int c1; int c=0; bool coff = false; bool actB = false; unsigned long time2; //servos Servo servoR; Servo servoL; unsigned long time1; int R=90,L=90; boolean c2=false; bool cs2=false; int c22=0; bool actS = false; //System bool systemF= false; void setup() { pinMode(ultra,OUTPUT); pinMode(echo,INPUT); attach(9); attach(10); pinMode(30,OUTPUT); pinMode(31,OUTPUT); pinMode(32,OUTPUT); pinMode(33,OUTPUT); pinMode(2,INPUT_PULLUP); pinMode(7,OUTPUT); write(0); write(180); setIntensity(7); } void loop() { push=digitalRead(2); if(push==0){ dist=100; actS=!actS; actB=!actB; cs2=!cs2; c2=!c2; msgact=!msgact; systemF=false; time1=millis(); time2=millis(); time3=millis(); time4=millis(); analogWrite(7,0); RGBoff(); } if(dist>0 && dist<50 && distOk == true && systemF == false){ actS=!actS; actB=!actB; cs2=!cs2; c2=!c2; msgact=!msgact; time1=millis(); time2=millis(); time3=millis(); time4=micros(); systemF=true;} if(c==0 && coff == false && actB==true){ analogWrite(7,277); RGBon();} if((millis() - time1 )>= 100 && c==0 && coff==false && actB==true){ analogWrite(7,0); coff=!coff; RGBoff(); time1=millis();} if((millis() – time1 )>= 350 && c==0 && coff==true&& actB==true){ c++; coff=!coff; time1=millis();} if(c==1 && coff==false&& actB==true){ analogWrite(7,277); RGBon();} if((millis() – time1 ) >= 100 && c==1&& coff==false && actB==true){ analogWrite(7,0); RGBoff(); coff=!coff; time1=millis();} if((millis() – time1 )>= 350 && c==1 && coff==true && actB==true){ c++; coff=!coff; time1=millis();} if(c==2 && coff==false && actB==true){ analogWrite(7,277); RGBon();} if(millis() – time1 >= 100 && c==2 && coff==false && actB==true){ analogWrite(7,0); coff=!coff; time1=millis();} if((millis() – time1 )>= 150 && c==2 && coff==true && actB==true){ c++; coff=!coff; time1=millis();} if(c==3 && coff==false && actB==true){ analogWrite(7,277); RGBon();} if(millis() – time1 >= 100 && c==3 && coff==false && actB==true){ analogWrite(7,0); RGBoff(); coff=!coff; time1=millis();} if((millis() – time1 )>= 150 && c==3 && coff==true && actB==true){ c++; coff=!coff; time1=millis();} if(c==4 && coff==false && actB==true){ analogWrite(7,277); RGBon();} if(millis() – time1 >= 100 && c==4 && coff==false && actB==true){ analogWrite(7,0); RGBoff(); coff=!coff; time1=millis();} if((millis() – time1 )>= 350 && c==4 && coff==true && actB==true){ c=0; coff=!coff; time1=millis();} // Servos if(c2==true && cs2==true && c22==0 && actS==true){ if(R==150 && L==30){time2=millis( );c22++;c2=false;} write(R); write(L); if(millis()-time2 >=5 && c22==0){ L–;R++; time2=millis(); } } if((millis()-time2 >=1000) && c2==false && actS==true){ c2=true;time2=millis(); } if(c2==true && cs2==true && c22==1 && actS==true){ if(R==30 && L==150){time2=millis();c22=0;} write( R); write(L); if(millis()-time2 >=5 && c22==1){ L++;R–; time2=millis(); } } //matrix if (i < ancpal * msg.length() + m1.width() - 1 - esp && ok == true && Mprint == false && msgact==true){ i++;m1.fillScreen(LOW ); ok=false; l = i / ancpal; x = (m1.width() - 1) - i % ancpal; if(i >= ancpal * msg.length() + m1.width() – 1 – esp){i=0;} } if ( x + ancpal – esp >= 0 && l >= 0 && ok == false && Mprint == false && msgact==true) { if ( l < msg.length() ) { drawChar(x, 1, msg, HIGH, LOW, 1); } l--; x -= ancpal; } else if(Mprint == false && msgact==true) { ok=true; time3=millis(); Mprint=true;m1.write();} if(millis() - time3 >= w8 && ok ==true && Mprint==true && msgact==true){ Mprint=false;} //Ultrasound if(systemF = = false){ if(micros()-time4>=10 && c5== 0){ digitalWrite(ultra,LOW); c5++; time4=micros();} if(micros()-time4>=10 && c5== 1){ digitalWrite(ultra,HIGH); c5++; time4=micros();} if(micros()-time4>=20 && c5==…
