Yes we can. Bmp is easy format. Open image in notepad, see the characters, transmit on rs232 first nd see the integrity. Then superimpose on power line. This is how i would prefer to do.
I am not from engineering background, I want few clarifications. 1. Putting a 100 ohm/1 Watt resistor at input of whetstone bridge will cause voltage divider circuit, causing input voltage of Wheatstone bridge to vary, which will cause measured voltage on Wheatstone bridge to vary with temperature as a function of input voltage variation due to divider circuit causing nonlinearity between temperature and measured voltage. 2. Wheatstone bridge itself is a voltage divider circuit, so resistance change of rtd sensor with temperature change cause nonlinearity in temperature and voltage. 3. Map function of Arduino is a linear transformation from one scale to other, plus it is an integer math not resulting in floating point temperatures if required. How can actually one compensate for nonlinearity between voltage and temperature in arduino?
@@RUPJITCHOWDHURY God bless your sweet spirit and thank you for sharing! I’ve been building amplifiers recently and home power is very noisy. Wall warts etc. is there some secret filtering inside of radios that gets rid of high frequency interference? I can’t find anything on RU-vid that covers this problem.
@@generalleigh7387 if there is noise use power line filters. That would help a lot. Most of the home AM SW radios are battery powered. You are right , the sound is very clean
@@RUPJITCHOWDHURY so what? Did you try to use a low external voltage reference say 1 v and use it to read mili volt directly? 1V external reference will give 1mv precision on Arduino ADC...
@ahmadihamdanmusman3472 yes, you can use lm324 in differential amplifier mode or instrumentation amplifier mode. Like I used in the video. See the circuit diagram for reference.
