@0904-mansi: Someone else here may have a better ideas, but you might want to start by browsing the projects at https://github.com/fossasia and looking to see which interest you. Most will have documentation about how to chat with the project team. For example this project Pocket Science Lab you can ask questions here. But each project will be a little bit different in how they work so you'll want to watch, ask, and learn.
ok, sir !! Thanku so much you helped me a lot🤗🤗
Required packages are missing, run
npm install from this directory to install them.whereas I have run npm install 3 times again and again it is throwing this error what should I do? Please help
Thank you!!

This could be interesting for PSLab as well:

Dear @/all Please join our weekly open hardware call on Saturday at 17:00 CET / 21:30 IST. Please register at https://eventyay.com/e/1873937b
In this meeting we discuss the progress and next steps of the new Pocket Science Lab version (https://pslab.io), development, firmware, Android app and production questions. If you would like to share updates on other projects you are working on, you are welcome too!
After registering you can click the "Join event" button on the event page and then click on the video room link on the left to participate in the meeting.
Any comments?
this is a nice cheat sheet for sending patches via email 📧 👩💻
Good news: The basic test of the replaced power chips all function normally, including the charging, discharging, power supply with/without the battery. 10V boost circuit, -10V capacitor pump, +6V and -6V voltage source.
I add a button to control the IP5189T power bank IC. Press the button to turn it on, press 2 times to turn it off. The power bank IC will measure the current, if the current is less than 45mA, it will cut-off the output after 40 seconds.
I've replace the MCP6S21 with a MAX5400 digital potentiometer and a TL082 general operational amplifier.
I've replace the 4 channel DAC MCP4728 with 2 two channel DAC MCP4822, if there is no strong synchronization between different DAC channels. I think it's OK because the 4 amplifing circuits after DAC are pretty different, so there may be no requirement for synchronization between DAC channels.
I've add a 74HC4051 to handle the Chip-Select pins which are newly added.
Bad news: I only bought 2 pieces of IP5189 for testing, I checked there are more than 3000 pieces when I chose to test it, but now there are none left. I may need to test IP5219 instead or wait for a while.
The datasheets are here http://www.injoinic.com/product_detail/id/21.html
I need PIC24 chips and a debugger if there are some to further test with modifying the firmware.
Story of Arduino.. https://blog.arduino.cc/2021/12/09/one-board-to-rule-them-all-history-of-the-arduino-uno/
Being a engineer for years, Arduino is not my option in any of my projects. It's comparably expensive, poor-porformance, poor-designed. The true story that they use Atmega MCU is that there space have several thousands of Atmega by coincidence. Not a solid reason. To some extent, we say that Arduino saved Atmel.
The toolchain is poor. IDE is poor, even the default font is ugly for programming.
It has done some help to newbies, but the terminology they used is not accurate in software field. It will make Arduino users harder to understand the development of MCU programming, vice-versa.
They have done nearly none contribution to the electronics and software world outside of Arduino. They could have done better job to let the software community contribute to more general embedded programming.
I don't have much experience developing Arduino related projects and whenever I have any better choice, I will not use it.
