I created an Arduino library to talk to Twitter using its Web API made for ESP8266. There are other approaches like using a bearer token arduino-twitter-api, but comes with limitations in terms of not being able to send tweet. This Arduino library TwitterWebAPI can both search/read and post tweets.
All the instructions and usage of library is described on my GitHub library page Github: debsahu/TwitterWebAPI
An Arduino library to talk to Twitter using Twitter Web API made for ESP8266. This is based on a sketch posted here. There are other approaches like using a bearer token arduino-twitter-api, but there are limitations in terms of not being able to send tweet. This can both search/read and post tweets.
In order to talk to Twitter,
Fill the obtained Consumer Key, Consumer Secret, Access Token and Access Token Secret inside the sketch.
To use in your sketch include these lines.
#include <TwitterWebAPI.h>
#include <NTPClient.h>
#include <WiFiUdp.h>
Define Twitter GET request timeout (optional, default is 1500ms)
#define TWI_TIMEOUT 2000 // in msec
Setup correct timezone to correct the time obtained from NTP server.
const char *ntp_server = "pool.ntp.org"; // time1.google.com, time.nist.gov, pool.ntp.org
int timezone = -5; // US Eastern timezone -05:00 HRS
You WILL need Consumer Key, Consumer Secret, Access Token and Access Token Secret that can be obtained from the above steps.
// Values below are just a placeholder
// Obtain these by creating an app @ https://apps.twitter.com/
static char const consumer_key[] = "gkyjeH3EF32NJfiuheuyf8623";
static char const consumer_sec[] = "HbY5h$N86hg5jjd987HGFsRjJcMkjLaJw44628sOh353gI3H23";
static char const accesstoken[] = "041657084136508135-F3BE63U4Y6b346kj6bnkdlvnjbGsd3V";
static char const accesstoken_sec[] = "bsekjH8YT3dCWDdsgsdHUgdBiosesDgv43rknU4YY56Tj";
Declare clients before setup().
WiFiUDP ntpUDP;
NTPClient timeClient(ntpUDP, ntp_server, timezone*3600, 60000); // NTP server pool, offset (in seconds), update interval (in milliseconds)
TwitterClient tcr(timeClient, consumer_key, consumer_sec, accesstoken, accesstoken_sec);
In setup make sure to start NTP connection. A correct time is required to be able to post/search on Twitter.
tcr.startNTP();
Search for a key word
std::string search_str;
String tmsg = tcr.searchTwitter(search_str);
Search Twitter User Info (eg follower count)
std::string search_str;
tcr.searchUser(search_str);
Post to Twitter
std::string twitter_post_msg;
tcr.tweet(twitter_post_msg);
In addition to TwitterWebAPI, make sure that TimeLib library and NTPClient library is installed, and install the following libraries
