Encoder and decoder is for transmitting digital values without the use of microcontroller. Serial character data can be transmitted only by the microcontroller.
July 27, 2016 at 8:42 am in reply to: How to make wireless notice board using arduino and hc-05 #14088Prabakaran P MParticipantCheck the setup function. It is not called??? or else make the setup codes away from the functions.
Prabakaran P MParticipantYes, It is possible by changing or altering two components of a UPS.
1. Transformer- It is rated VA, increase the rating of it.
2. Switching device(IGBT,MOSFET,SCR, Etc.,) – Increase the number of devices to match the output rating.
Prabakaran P MParticipantRefer to the articles related to ESP8266 in this website
Prabakaran P MParticipantYou need to find two things, 1. Power requirement and choosing a power supply?
2. Type of interface the LCD has?
Prabakaran P MParticipantI hope it is poissible and you can proceed with the same idealogy which you showed in the code.
July 26, 2016 at 9:55 am in reply to: how to to measure L1phase , L2 Phase and L3 Phase for phase shift difference for same 50Hz frequency sine in microcontroller #14083Prabakaran P MParticipantFor checking the Phase presence, i would suggest you to go for digital checking of the phases using a transformerless AC-DC conversion.
Prabakaran P MParticipantJuly 26, 2016 at 9:45 am in reply to: unable to differ between pwm and continious input through 74HC165 for dotmatrix display #14081Prabakaran P MParticipantI assume it is not a PWM signal. It may me acting as a pulse for shifting the LEDs in the dot matrix to create a scrolling effect. Imagine a shift register to create a scrolling effect.
Prabakaran P MParticipantyou can refer uart tutorial of the PIC16F4550 in this website to sent the data to computer…. For detecting the sensors checking the status of the input pin inside a while loop or you can also use interrupt to detect.
Prabakaran P MParticipantwhy can't you try a variable regulator which give 4.4v output??
Prabakaran P MParticipantAs per my understanding it is connected through RF 433Mhz transciever
Prabakaran P MParticipantyou can try PCM library code by Michael Smith.
just search for it…..
Prabakaran P MParticipantvoid loop() {if(x<1){sampler1.load("1.wav");sampler1.splay(10);}sampler1.buffill();x++;}The if loop in the above code is making it to run only oncePrabakaran P MParticipantAs of now there is wireless chargers which can work for some centimeter, I don't think it is possible. Future may give you the answer.
