Hi everyone,
I´m new in ubidots and I have found a problem that I hope someone could help me.
I need to make a counter with a push button and send the number to ubidots. When I push the botton I have a delay and some pulses are missing. If I disable the send to ubidots the scketch works well with the serial port.
I would like to know if there are any solution or what I’m doing wrong.
// this constant won't change:
const int buttonPin = 2; // the pin that the pushbutton is attached to
// Variables will change:
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
#include <Ethernet.h>
#include <SPI.h>
#include <UbidotsEthernet.h>
#define ID "XXXXXXXX" // Put here your Ubidots variable ID
//#define ID2 "Your_variable_ID2_here"
#define TOKEN "XXXXXXXXX" // Put here your Ubidots TOKEN
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
// Set the static IP address to use if the DHCP fails to assign
IPAddress ip(192, 168, 0, 177);
Ubidots client(TOKEN);
void setup() {
// initialize the button pin as a input:
pinMode(buttonPin, INPUT);
Serial.begin(9600);
// start the Ethernet connection:
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// try to congifure using IP address instead of DHCP:
Ethernet.begin(mac, ip);
}
// give the Ethernet shield a second to initialize:
delay(1000);
}
void loop() {
// read the pushbutton input pin:
buttonState = digitalRead(buttonPin);
// compare the buttonState to its previous state
if (buttonState != lastButtonState) {
// if the state has changed, increment the counter
if (buttonState == HIGH) {
// if the current state is HIGH then the button
// wend from off to on:
buttonPushCounter++;
Serial.println("on");
Serial.print("number of button pushes: ");
Serial.println(buttonPushCounter);
sendtoubidots();
} else {
// if the current state is LOW then the button
// wend from on to off:
Serial.println("off");
}
// Delay a little bit to avoid bouncing
delay(50);
}
// save the current state as the last state,
//for next time through the loop
lastButtonState = buttonState;
}
void sendtoubidots() {
client.add(ID, buttonPushCounter);
client.sendAll();
}
