I have already seen the other post but I want a python code through with I can connect my raspberry pi and ECG sensor ad8232 I am totally new to raspberry pi interfacing so I don’t completely understand the datasheet of the sensor and how to extract important info from it and use it in python code so please help me I need it for my project please helpsensorpython-3ShareEditFollowClose 4Flagasked 21 hours agoManjeet Singh1111 bronze badge New contributor

  • @Manjeet Singh, Welcome and nice to meet you. Ah, let me see. (1) A year ago I start playing with AD8232 ECG and found it a good educational toy to learn Rpi, ADC etc. I learn other things such as how to reduce noise etc. My old post is a bit out out dae, because I recommended to use AdaFruit Circuit Python. Perhaps I can take this opportunity to update my answer. – tlfong01 20 hours ago   
  • @Manjeet Singh, You might like to let me know more about you background, knowledge and skills. For example, (1) Do you know Ohm’s Law, how to use a multi-meter? (2) Do you know how to use Arduino to blink a LED, and its on board 10-bit ADC to convert any analog signals? (3) Do your school/college have any oscilloscope to display ECG signals? – tlfong01 20 hours ago   
  • @Manjeet Singh, (1) Since your Rpi project spec is on python, I would recommend you to start off getting familiar with Rpi OS buster GUIThonny python IDE v3.3.0+. (2) You might like to write toy programs such as blinking a LED. Please feel free to make comments or counter suggestions. I would hold my answer for you to catch up. It would be nice if you can report your project project in your school/college project blog or website. Cheers. – tlfong01 19 hours ago   
  • BTW, if you have not really started trying Rpi1/2/3/4, I would suggest you to consider the new US$4 Rpi Pico which can use Thonny MicroPython. The good things with Pico is that it has built in 12-bit ADC pins to interface ADC8232. You can goolge Rpi Picro ADC projects to find more details. – tlfong01 18 hours ago    
  • In case you prefer Rpi 3/4 over pico for some reasons, you might like to read my answer to the following Q&A on hints to design “Right Leg” circuit and solve noise problems.
