Either my inbox (msgs) or my Inbox link has a problem...

On each page that has a link to my INBOX, I am showing: INBOX (1)When I click on it, and go to the inbox, the top message is about one day old and I see nothing new. No new PM, so either there is a new one and it is not showing, or there isn't one and the indicator for how many new messages I have in my inbox is wrong.

I2C addresses > 63 are not usable with atTiny85?

Hi I have a big problem with addressing multiple attiny85-chips with I2C: For what I know the attiny uses 7-bit addresses for communication. I am using the TinyWireS lib, which works perfectly fine for me, untill I am reaching address: '64' which is '1000000' in binary. The highest usable address should be '1111111'. Here is the attiny85 datesheet. This is what happens: Slave: Attiny85: switches led on or off when msg is received over I2C. Slaveaddress: 64 #include #include #define output (4) #define I2C_SLAVE_ADDR (64) //works if I2C_SLAVE_ADDR < 64 void setup() {   TinyWireS.begin(I2C_SLAVE_ADDR);   pinMode(output, OUTPUT); } volatile bool state = LOW; void loop() {   byte msg = -1;   if(TinyWireS.available())     msg = TinyWireS.receive();   if(msg == 1)     state = HIGH;   else if(msg == 0)     state = LOW;   else if(msg == 2)     state = !state;   digitalWrite(output, state); } Master: Arduino pro mini: sendMsg(0, true); //works! led on chip: 64 switches on sendMsg(64, true); //fails! led on chip: 64 is off. #include #define DEVICE (64) //0 works! void setup() {     Wire.begin(); } void loop() {     sendMsg(1, DEVICE);     delay(2000);     sendMsg(0, DEVICE);     delay(2000); } void sendMsg(int msg, int device) {     Wire.beginTransmission(device);     Wire.write(msg);     Wire.endTransmission(); } Have you any idea how to solve this problem?

Ible delayed posting no longer new.

If you have an ible delayed of being posted for who knows what reason. When it gets posted it gets posted in the spot that it would of been  originally. Example, on 6/1 i published 3 ibles in one day. One posted in 10 minutes. The other 2 posted on 6/4. Now the two late posts do not get put at the top with the new ibles, no it gets put in at the date it was first submitted. My variable voltage supply took 6 days to post. So to find it you have to go through many pages of ibles to locate it. IT does not get posted as the newest ible. I had sent a msg to service@instructables but never did get a real person.    If peoples ibles are delayed for some flagging issue or what ever it would be nice to know what to avoid in the future. I have gotten a tip on some issues that may trip the filters, short keywords, not common or unrecognizable keywords. Such as eek. In msg or forums delays maybe from short question with active links.. These are tips are from someone that has been observing these things and are not a locked in rule.   Altho these are somewhat of gripes it is not anything that will stop me from posting ibles. I realy gain from Instructables. Before i joined here i never heard of Arduino now i am writing small sketches and manipulating larger ones.

Hi, i am trying to have it switch a 5v relay on pin 8 receiver side only when pin 2 transmitter side in held down. I have set up a XY-MK 5v transmitter , Push button to pin 2 live when pushed 3.3v Data rf transmitter to pin 4 and 5v,gnd and receiver, data pin 2 5v and gnd led to pin 8 and gnd Here are the codes. Transmitter Code= #include const int button = 2; const int transmit_pin = 4; const int receive_pin = 2; const int transmit_en_pin = 3; void setup() {   // Initialise the IO and ISR   Serial.begin(9600);   vw_set_tx_pin(transmit_pin);   vw_set_rx_pin(receive_pin);   vw_set_ptt_pin(transmit_en_pin);   vw_set_ptt_inverted(true); // Required for DR3100   vw_setup(2000);  // Bits per sec } byte count = 1; void loop() {   char msg[7] = {'h','e','l','l','o',' ','#'};   if     (digitalRead(button) == HIGH)   {Serial.println("on its way");   msg[6] = count;   //digitalWrite(led_pin, HIGH); // Flash a light to show transmitting   vw_send((uint8_t *)msg, 7);   Serial.println("on its way");   vw_wait_tx(); // Wait until the whole message is gone   //digitalWrite(led_pin, LOW);   //delay(1000);   count = count + 1; } } And receiver code = #include const int led_pin = 8; const int transmit_pin = 12; const int receive_pin = 2; const int transmit_en_pin = 3; void setup() {     delay(1000);     Serial.begin(9600); // Debugging only     Serial.println("setup");     // Initialise the IO and ISR     vw_set_tx_pin(transmit_pin);     vw_set_rx_pin(receive_pin);     vw_set_ptt_pin(transmit_en_pin);     vw_set_ptt_inverted(true); // Required for DR3100     vw_setup(2000);  // Bits per sec     vw_rx_start();       // Start the receiver PLL running } void loop() {     uint8_t buf[VW_MAX_MESSAGE_LEN];     uint8_t buflen = VW_MAX_MESSAGE_LEN;     if (vw_get_message(buf, &buflen;)) // Non-blocking     { int i;         digitalWrite(led_pin, HIGH); // Flash a light to show received good message // Message with a good checksum received, print it. Serial.print("Got: "); for (i = 0; i < buflen; i++) {      Serial.print(buf[i], HEX);      Serial.print(' '); } Serial.println();         digitalWrite(led_pin, LOW);     } } I have tried many different codes i have found and this works the best but.........the voltage is only going from 0.20v to 0.40 on the receiver pin 8. i need this to be 5v any ideas?

Arduino project

HiWonder if someone can help me with this code.Im using the arduino uno board with the sim808.Everything is working fine but can only work in stages.

: Arduino + Adafruit wave sheild + IR + Keypad sound board

Hi , was wondering if you could point me in the right direction I'm very new to Arduino I built last year a simple board with adafruit wave shield and added a simple 12 digit key pad to play 12 sounds + power up I have got the codes for the KEYES IR receiver so know the IR is correctly connected and library loaded im trying to integrate the IR code so can change the sounds by IR remote ideally with option of the buttons (if have to loose the buttons and just use remote that's fine) have copied the code below for how it works now just buttons   I found some code for Cylon Pumpkin that works great with just the remote but would also like to integrate the 12 digit keypad Thank you in advance for any help or pointers you can suggest Richard CODE FOR 12 DIGIT BUTTON PRESS /* ADAVOICE is an Arduino-based voice pitch changer plus WAV playback. Fun for Halloween costumes, comic convention getups and other shenanigans! Hardware requirements: - Arduino Uno, Duemilanove or Diecimila (not Mega or Leonardo compatible). - Adafruit Wave Shield - Speaker attached to Wave Shield output - Battery for portable use If using the voice pitch changer, you will also need: - Adafruit Microphone Breakout - 10K potentiometer for setting pitch (or hardcode in sketch) If using the WAV playback, you will also need: - SD card - Keypad, buttons or other sensor(s) for triggering sounds Software requirements: - WaveHC library for Arduino - Demo WAV files on FAT-formatted SD card This example sketch uses a 3x4 keypad for triggering sounds...but with some changes could be adapted to use several discrete buttons, Hall effect sensors, force-sensing resistors (FSRs), I2C keypads, etc. (or if you just want the voice effect, no buttons at all). Connections: - 3.3V to mic amp+, 1 leg of potentiometer and Arduino AREF pin - GND to mic amp-, opposite leg of potentiometer - Analog pin 0 to mic amp output - Analog pin 1 to center tap of potentiometer - Wave Shield output to speaker or amplifier - Matrix is wired to pins A2, A3, A4, A5 (rows) and 6, 7, 8 (columns) - Wave shield is assumed wired as in product tutorial Potentiometer sets playback pitch. Pitch adjustment does NOT work in realtime -- audio sampling requires 100% of the ADC. Pitch setting is read at startup (or reset) and after a WAV finishes playing. POINT SPEAKER AWAY FROM MIC to avoid feedback.

How to get data from a load sensor through bluetooth module on an Android App/Arduino?

I am creating a mobile android application which gets data from a load sensor connected to HC-06 Bluetooth module and sends the data to a mobile application. The mobile app has two activities one for listing the bluetooth devices available and the other is the main activity to get data from the load sensor. I have managed to connect/pair with the Bluetooth module but I am unable to get data from it. The main activity consists of a button 'btnScan' that will get the data, and a text field to display the data. Can someone please help?  Here is the MainActivity File package com.uniproj.senseplate; import; import; import; import java.util.UUID; import; import android.bluetooth.BluetoothAdapter; import android.bluetooth.BluetoothDevice;
