The following projects show how capable Arduino is. Link: Arduino Ant Hexapod Robot CNC Machines Arduino Projects With that it can detect objects in front, and it can even strike if the object is present if front of it. The ant also has built-in ultrasonic sensor in the head.

We can control the ant robot via Bluetooth and a smartphone, or radio communication.

I also designed a custom PCB which acts as an Arduino Mega Shield so we can easily attach all servo connects. We need MEGA because it’s the only board that can control more than 12 servos using the Servo library. The brain of the robot is an Arduino Mega. That means that we need total of 18 servos for this project, and additionally 3 servos for the head movements and 1 servo for the tail.

Also, if you read any character other than \ n and \ r, it means that the line is not blank.Each leg have three joints, and for each joint we need a servo motor. If we get here, it is because the request has been read in full. And, after the previous line, it is: \ r \ nso. We see that the last line of the request is: \ r \ n alone, \ r \ n. Apenas a primeira linha da requisição nos interessa Faz a leitura da primeira linha da requisição char* readRequest(WiFiEspClient client) Here, we have the reading of the first line of the request.

What does it do? When we press a button on the smartphone, the function sends the command in HTTP to ESP8266, using only the first line, as you see in the example below. Tempo para o navegador receber os dados Executamos a ação com o valor passado na requisiçãoĮxecute(getAction(request), getValue(request)) WiFiEspClient client = server.available() We determine a time for the browser to receive the data and close the connection with the client.

We then read the sensors and send the response to the customer. We read the request and, if the request is not for the favicon, we execute the action with the value passed in the request. Serial.println("Sensor não encontrado!") Inicializa o sensor DS18B20 void setupDS18B20() Serial onde está o ESP-01 com o firmware AT já instalado We wait to connect to the WiFi network, configure the IP, and verify the same IP.

Here, we perform a function that initializes the serial where the ESP-01 is with the AT firmware already installed. Coloca os pinos que estão ligados os relês como saída In this step, we put the pins that are connected to the relays as outputs. Para o sensor de luminosidade apenas precisamos ler o pino analógico Serial onde está o ESP-01 com firmware AT We also initialize the WiFi and connect to the network. For the brightness sensor, we just need to read the analog pin. We initialize the serial and serial monitor where the ESP-01 is with AT firmware, in addition to pins, and DS18B20 and DHT22 sensors. Mantém o estado atual dos pinos (HIGH ou LOW) Variáveis para armazenar os valores dos sensores Servidor que receberá as requisições na porta 80 (porta padrão http) SSID e senha da rede wifi para o ESP se conectar Sensor de Temperatura DS18B20 OneWire oneWire(PIN_DS18B20) We point to the server that will receive the requests on port 80 (standard port http), as well as the variables to store the values of the sensors.

We then set out for definitions involving the WiFi network, such as the SSID and password for the ESP to connect. We continue with the DS18B20 temperature sensor, and the DHT22 temperature and humidity sensor. #define PINS_COUNT 16 //Quantos pinos a partir do primeiro serão utilizados #define FIRST_PIN 36 //Pino onde está o primeiro relê We also point out the pin where the first relay will be and how many pins (starting from this first one) will be used. We start off by including the libraries and defining the pins attached to the sensors.
