Message 'The Twitter REST API v1 is no longer active. Please migrate to API v1.1'

问题 This is my Python code that does not work anymore. I get this message: "The Twitter REST API v1 is no longer active. Please migrate to API v1.1". The Python code basically uses the Python-Twitter library to ask Twitter for the status of user "x", and it then takes the last status and searches for the term "#driptwit". If found, it sends the ASCII value of 1 to the serial port (and to the Arduino). If #driptwitstop is found, it sends an ASCII value of 0. Lastly, it loops and checks the Twitter

C# console application talking to Arduino via Bluetooth

由 岁酱吖の 提交于 2019-12-21 06:03:35
问题 Not a whole lot to say here other than this doesn't work, and I have no idea why. The serial output on the Arduino is nothing. The output on the C# code goes down to waiting for a response and then nothing. The Bluetooth card LED on the Arduino goes green when I start the C# program so there is a connection being made. Just nothing else. Arduino Code #include <SoftwareSerial.h> //Software Serial Port #define RxD 8 // This is the pin that the Bluetooth (BT_TX) will transmit to the Arduino (RxD

Twisted Python script on Raspberry Pi (Debian) to communicate with Arduino via USB

由 拜拜、爱过 提交于 2019-12-21 05:25:05
问题 I have been working on an Arduino/Raspberry Pi project where I have found myself learning not just Python but Twisted Python as well; so I apologize in advance for my newbness. I am trying to keep it simple for now and just trying to send a char at any one time between the two devices. So far I am able to send from the Raspberry Pi to the Arduino and effectively turn its LED off/on just as expected. However I cannot seem to generate Twisted code which will detect anything coming from the

how to stop a loop arduino

由 耗尽温柔 提交于 2019-12-20 18:53:18
问题 I have this loop, how would I end the loop? void loop() { // read the pushbutton input pin: a ++; Serial.println(a); analogWrite(speakerOut, NULL); if(a > 50 && a < 300){ analogWrite(speakerOut, 200); } if(a <= 49){ analogWrite(speakerOut, NULL); } if(a >= 300 && a <= 2499){ analogWrite(speakerOut, NULL); } 回答1: Arduino specifically provides absolutely no way to exit their loop function, as exhibited by the code that actually runs it: setup(); for (;;) { loop(); if (serialEventRun)

Arduino HIGH LOW

由 自古美人都是妖i 提交于 2019-12-20 17:28:10
问题 I have an Arduino and I am wondering exactly what HIGH and LOW mean as far as actual values go... Are they signed ints? Unsigned ints? Unsigned chars??? What are their values? I am guessing that HIGH and LOW are probably unsigned ints with all of the bits set to 1 and 0 respectively, but I'm not sure. I would like to be able to do bitwise operations using HIGH and LOW or pass values other than HIGH or LOW to digitalWrite. Also, how would I cast an integer to HIGH or LOW so I could do this?

Arduino系列之按键模块（一）

由 主宰稳场 提交于 2019-12-20 16:27:22
今天我将简单介绍按键模块计数的原理： 我们常用的按键及按键模块有2脚和4脚的，其内部结构如图所示，当按下按键时就会接通按键两端，当放开时，两端自然断开。 Arduino接发图： 接下来我们讲讲思路： 我们需要定义一个按键，为第几端口； 我们需要定义一个全局变量count，用来计数； 在初始化中，我们需要定义串口波特率，一般为9600； 定义按键为输入模式； 在循环中，我们不断检测按键是否为高电位 如果为高电位，则计数加1； 反之，不做动作 打印出结果 具体代码如下： #define anjian 4 //定义按键脚 int count=29; //定义初始count值 void setup() { Serial.begin(9600); //设置波特率 pinMode(anjian,INPUT); //设置按键脚为输入模式 } void loop() { if(digitalRead(anjian)==HIGH) // 当检测到按键按下时 { delay(2); count=count+1; //计数加1 } Serial.println(count); //打印出count值 delay(500); //延时一段时间再次检测 } 来源： https://www.cnblogs.com/fqhy/p/7986228.html

Arduino serial data parsing

由 时间秒杀一切 提交于 2019-12-20 10:55:33
问题 I'm writing an app to control my robot with my Android phone over Bluetooth, everything is goes well, data is echoed and verified, but I'm having some trouble with the protocol, specifically I want my robot's wheels to turn when I send a command such as s,10,100 or s,-30,-10 ... (values in percent). My problem is that when I want to parse my wheel speed command on my Arduino I must parse from up to 4 separate bytes to int , for example s,-100,-100 makes my robot go backwards at full speed,

Clearing the terminal screen?

由 拥有回忆 提交于 2019-12-20 10:32:41
问题 I'm reading data from 9 different sensors for my robot and I need to display them all steadily, in the same window so I can compare the values and see if any of the readings is off. The problem I'm having with both Serial.print and lcd.print is that the values are constantly moving and I can't really have a good look at them while moving the robot. I was thinking to call something like Serial.clear() before displaying anything else and that would just keep things steady and in one place,
