• |(operador de bits OR) 
• ^ (operador de bits XOR) 
• ~ (operador de bits NOT) 
• << (desvio à esquerda) 
• >> (desvio à direita) 
• &= (de bits composto AND) 
• |= (de bits composto OR) 
 
Operadores compostos 
• ++(incrementar) 
• – (decrementar) 
• += (adição composta) 
• -= (subtração composta) 
• *= (multiplicação composta) 
• /= (divisão composta) 
 
VARIÁVEIS 
Variáveis são expressões que você pode 
usar em programas para armazenar valores 
como a leitura de um sensor em um pino 
analógico. 
 
Constantes 
• HIGH | LOW 
• INPUT | OUTPUT 
• true | false 
• Constantes inteiras 
 
Tipos de dados 
Variáveis podem ser de vários tipos: 
• boolean 
• char 
• byte 
• int 
• unsigned int 
• long 
• unsigned long 
• float 
• double 
• string 
• array 
• void 
 
Conversão 
• char() 
• byte() 
• int() 
• long() 
• float() 
 
Comunicação serial 
Usado para comunicação entre a placa 
Arduino e um computador ou outros 
dispositivos. Esta comunicação ocorre 
através dos conectores serial ou USB da 
placa Arduino e nos pinos digitais 0 (RX) e 1 
(TX). Assim, se você utilizar estas funções 
não poderá utilizar os pinos 0 e 1 para 
entrada e saída digital. 
• Serial.begin(speed) 
• int Serial.available() 
• int Serial.read() 
• Serial.flush() 
• Serial.print(data) 
• Serial.println(data)
