This module size is only 11.2mm x 11mm. TEA 5767 supports I2C.  Pinout and wiring: For antenna i have used just 75 cm long wire, because that is 1/4 [...]Posted by alin at 23:12 Tagged with: TEA 5767, TEA 5767 datasheetMonitorizarea amperajului cu ajutorul senzorului ACS712Fără categorieNo Responses »Ian 022013int VQ; int ACSPin = A2;void setup() { Serial.begin(9600); VQ = determineVQ(ACSPin); //Quiscent output voltage – the average voltage ACS712 shows with no load (0 A) delay(1000); } void loop() { Serial.print(“ACS712@A2:”);Serial.print(readCurrent(ACSPin),3);Serial.println(” mA”); delay(150); } int determineVQ(int PIN) { Serial.print(“estimating avg. quiscent voltage:”); long VQ = 0; //read 5000 samples to stabilise value for (int [...]Posted by alin at 02:15 Tagged with: ACS712TMonitorizarea  tensiunii unei bateriFără categorieNo Responses »Ian 022013Since we are involved in off grid solar power systems, we have a need to monitor battery voltage. The Arduino can do this easily with a simple voltage divider. With some simple mods, we can control loads, generators, or notifications based on battery voltage. To read a maximum of 20vdc, R1 should be 3k ohm, [...]Posted by alin at 01:51Statie meteo -Arduino + LCD +  DHT11ArticoleNo Responses »Aug 192011First of all, you will need to wire the DHT11 sensor and the LCD as shown in the circuit diagram below: Loading the program to get the weather station going: The code for reading the Sensor data and displaying it on the LCD is available here, The code is very easy to read and understand and [...]Posted by alin at 13:24 Tagged with: 1402 Blue backlit LCD display, Arduino Duemilanove, Arduino ProtoShield, DHT11, Photo transistorCitirea unui senzor DHT11 Temp & Humidity cu ArduinoArticoleNo Responses »Aug 192011Participa si tu la dicutii pe forum !Posted by alin at 13:12Wii Motion Plus + ArduinoArticoleComentarii opriteFeb 022011Ok so I, after much research, have been able to read the gyro data of the new wii motion plus peripheral with the arduino microcontroller. With this code and the code previously developed for the wii nunchuck (here), we are able to create a 6 DOF IMU for under $40. Thanks Nintendo!
