Your video was very educational and simple. already tested with other micro drivers to make it smaller arduino type pro mini, nano. and also using mics that already have the wifi integrated as esp8266 and other app as virtuino
Hello sir, can i have the schematic diagram for this project sir ? I’m currently do a research for this kind of project. Your response greatly appreciated. Thanks
Hello Sir/madam, can I know the range of potential that can be measured using this code. I would like to know if I will be able to measure a potential say 0.123 V (or 123mV).
Yes. You just need to acquire the ADC value first, calculate it's voltage value, convert the value into string then send it via uart's tx pin. To me, the coding will be a lot easier if you use mikroelektronika C Compiler..
Thanks for the reply, now I just need to send multiple voltage values (instead of just one) to android via bluetooth. I think App Inventor can be used to design UI for android, but is there any recommended apps?
Fatin Nabihah Sairy Hi, you don't need any Bluetooth library for that. Bluetooth will automatically work through the Serial.println function. To solve your problem, try to disconnect the jumper from the TX pin of Bluetooth module to the RX pin of the Arduino when you are uploading the code. Reconnect the jumper when uploading process is done.
I've be looking for this stuff for ages lol all I need now is a current and Watt meter that can take a Max of 60v 20amp and monitor 13 18650s in series to ma fone lol
Hi, you could try building the curcuit using tutorial from ruclips.net/video/nexV5IFzDA0/видео.html (for reading high voltage) and ruclips.net/video/UF5jrnXvTlM/видео.html (for measuring high current)
Sorry sir, actually i'm still doesn't understand. Can you just explain which component what we use. And a part of modify the code as we want, that's for what? Sorry before, cause i'm still learning and need more knowledge. Thank you
Hi, you can refer to this link for schematic diagram: goo.gl/eqX5dd. The original code from the Arduino's Example is already perfect, we just modify it to make it more presentable. For example, the original code will just display solely the voltage value on screen like "1.52" and after some modification, we can make it display something like "Voltage: 1.52 Volts" by adding the 'Serial.print' or 'Serial.println' syntax. And the delay like delay(20); will make the reading more stable and the result would be more readable on the screen. Thanks for asking. Hope this helps! Note: 'Serial.print' is a bit different from 'Serial.println' command. The additional 'ln' means new line, which will make the Arduino print the next string in the new line. For example: Serial.print("Hello"); Serial.print(" world!"); will be displayed on the screen as Hello world! while Serial.println("Hello"); Serial.print(" world!"); will be displayed on the screen as Hello world! Similarly Serial.print("Voltage: "); Serial.print(voltage); Serial.print("V"); will be printed as Voltage: 1.34VVoltage: 1.34VVoltage: 1.34VVoltage: 1.34VVoltage: 1.34VVoltage: 1.34VVoltage: 1.34V while adding ln to the last Serial.print like this Serial.print("Voltage: "); Serial.print(voltage); Serial.println("V"); will make it be shown as Voltage: 1.34V Voltage: 1.34V Voltage: 1.34V Voltage: 1.34V Voltage: 1.34V Voltage: 1.34V Voltage: 1.34V Thanks!
idk why it took me so long to find this video but this is extremely helpful thank you
You are welcome :)

Thank you :)
Nice sharing ❤
Sir can you upload the code in the google drive

Hi, sorry for the delay. Here is the schematic diagram: goo.gl/eqX5dd. Thanks!
can I have the code sir...thanks
Hello Sir/madam, can I know the range of potential that can be measured using this code.
I would like to know if I will be able to measure a potential say 0.123 V (or 123mV).
The range is from 0 to 5V.
Thank you .
Yoe are welcome :)
Can we measure 0-40v
No you cannot. The limit is only 0-5V.
Can I use PIC16f877A with that bluetooth module instead of Arduino for this circuit?
Yes. You just need to acquire the ADC value first, calculate it's voltage value, convert the value into string then send it via uart's tx pin.
To me, the coding will be a lot easier if you use mikroelektronika C Compiler..

I think App Inventor can be used to design UI for android, but is there any recommended apps?
+eleongo I think the App Inventor itself should be enough as it already has the function to work with the Bluetooth things
do have i need a bluetooth library in my laptop to upload the coding? Because i cant upload the coding
Fatin Nabihah Sairy Hi, you don't need any Bluetooth library for that. Bluetooth will automatically work through the Serial.println function.

Code for Audrino

dave Yates hi, how are you
Sorry sir, actually i'm still doesn't understand. Can you just explain which component what we use. And a part of modify the code as we want, that's for what? Sorry before, cause i'm still learning and need more knowledge. Thank you

will make it be shown as
