Ok Sir. Thanks for the reply. I have selected the Following for my application:
1. Digital Potentiometer - AD5241
2. DAC IC - MCP4725
1. Both the Device are 5V supply operation.
2. Arduino UNO/ Mega has two I2C Port. Can use both for the same.
Have you used this? Kindly let us know.
My...
Hi Sir,
I am Planning to Interface Single channel Digital Potentiometer IC (1 M ohms) and Single Channel DAC IC to interface with Arduino Mega 2560. Can you Please share the Details of already used Single channel Digital Potentiometer IC(ranges from 0 to 1 M ohms) and Single channel DAC IC which...
Hi,
Thanks for the reply. Can you please share one sample arduino code of which listen TCP/IP connections on its assigned IP address.? This will be helpful to me.
For Development, I had Planned to use Arduino Mega and Ethernet Shield 2. After the
Development, I am Planning to use this...
Dear Sir,
I am planning to use Arduino mega + Ethernet shield board (16 Boards) with different IP address to interface with my PC using TCP/IP. I have to read and write data from PC to these boards and vice versa. Will it be possible? Kindly let me know.

Hi,
I am measuring the THD in the Transformer Secondary using the THD Meter which is showing high when compared to the Transformer Primary and also the...
Hi,
Please refer the link of Flat-topping relates to the Power quality and the harmonics:

Flat topping is affecting my system.
Non-linear power supplies draw current in high-amplitude short pulses that create...
Hi,
I had disconnected the Load, it is showing the Pure sinewave in the Transformer Secondary.
Flat topping occurs when the Load is connected.
How to resolve this Flat topping in the Transformer Secondary when the load is connected?
Kindly let us know.

V. Prakash
Hi,
Ok. I will try with 0-240V ac Primary tapping and give the feedback.
Yes. In the Post #1, I did not mention any load details. Sorry for that.
My AC Peak Current is 800 mA. load
In the +18V DC - 200 mA
In the -18V DC - 200 mA
Tx Primary(0-220V)--> Tx Secondary(22-0-22V) --> Bridge...
Hi,
Thanks for the reply.
1. I had Converted this secondary Tx AC Voltage --> Bridge rectifier --> LM 317 regulator --> +18V DC
without the bridge rectifier, i cant generate +18V DC.
In this case, How to remove the bridge rectifier.
2. If i use the Primary Transformer tapping 0-240V ac, this...
Hi,
Thanks for the reply.
1. I had used bridge rectifier at the Transformer secondary.
2. I had used 0-220V option in the Transformer Primary Input.
Kindly let us know how to avoid this Flat topping in the Transformer Secondary Waveform.

V. Prakash
Hi all,
Transformer Details:
Primary : 0-200-220-240V / 2A
Secondary1 : 24-22-20-0-20-22-24V / 72VA
Secondary2: 0-16.5 / 16.5VA
I had Found Primary Waveform 0-220v ac is Pure sine-wave and Found Flat Topping in the Sine-wave of 0-22Vac Secondary Tx as we attached in the image.
I had...
Dear Sir,
I have an Espressif's ESP32 IoT microcontroller. This device connects and sends data to the firebase database using the host address and authentication token.
Before sending the data I am making it as JSON format and sending. The Firebase database is able to receive that JSON file...
