11/08/2025
----------
studied about MAX30102 sensor and the interfacing with Arduino Uno, also try to code for measuring BPM and SPO2
12/08/2025
----------
Practicing BPM and SPO2 monitoring system
13/08/2025
----------
Exploring more about BPM and SPO2 monitoring
14/08/2025
----------
Partially done the project of measuring SPO2 and BPM using MAX30102. It gives some value, but sometimes it is showing some values out of normal range, and it is different from the values in the pulse oximeter. So I have to try more library functions with less usage of memory space and to avoid the current issue.
19/08/2025
----------
Partially got output for bpm and spo2 using max30102. but max30102 is not an option for medical / practical application. SO, explored more available sensors for the same.
22/08/2025
----------
Understood about the code logic of smriti and tested the smriti components with embedded c programming and verified through the activation of each component
25/08/2025
----------
got accurate and valid output of heart rate and spo2 using max30102 and arduino. Also it is showing fastest stabilization in output than earlier.
26/08/2025
----------
Studied the smriti code and tried to integrate the new code for bpm and spo2 that i have created into that smriti code.
27/08/2025
----------
Studied more about smriti code and try to integrate the code with another code which is more accurate for measuring heartrate and SPO2
11/09/2025: Studied about the components for wearable band and prepared the list.
15/09/2025
Studied about ADC calibration, worked with a circuit and designed circuit for voltmeter for measuring a battery voltage
18/09/2025
----------
prepared the minutes of the meeting which is held on 16/09/2025, explored about the heart rate and spo2 sensor for medical grade application, also explored about the sensor which is having the feature of sending the real time HR and SPO2 via API, Studied some theory parts
22/09/2025
----------
Modified and prepared the BoM for the wearable band project, studied some theory parts
24/09/2025
studied the basic procedure of measuring BP using the PPG signal, attended and prepared minutes for the meeting-connected health, doing the interfacing of smriti code and SPO2-BPM code
25/09/2025
working on the 8 channel project, developing the code for ADS for ESP, interfacing of SPI
09/10/25
attended the meeting regarding connected health, tried the coding of 8 channel eeg acquisition
14/10/2025
working on 8 cannel EEG acquisition using ESP and ADS1299 , checking the communication via SPI
29/10/2025
-----------
completed the integration of smriti , got the accurate values of heartrate and spo2
13/11/2025
-----------
Completed the integration of BLE code in SMRITI code. In this version, an external device which measures HR and SPO2 acts as a transmitter, and SMRITI , as a receiver which receives the real time datas from transmitter device.
17/11/2025
----------
Started the work of camera for SMRITI project using Ameba. Trying to develop the code for connecting the AMB82 with wifi and returning the IP to the hotspot device
21/11/2025
----------
Working on smriti with battery charging indication through leds
25/11/2025
----------
Completed the battery level indication in SMRITI. Voltage value from the battery is taken across the adc of esp32, and it is converted into percentage with the help of battery calibration, and based on the battery percentage, the LEDs are blinking as an indicator
28/11/2025
----------
Working with AMB82 video streaming. Target is to connect to a known wifi and start video streaming. the ssid and password should receive from another device and conect to the wifi using these credentials, after that amb82 should return its ip to the device which transmits the ssid and password
19/1/2026
---------
prepared document about all the firmware codes and its features that i have done till now
20/01/2026
Developing a code for communicating pulse oximeter device with smriti via ble. the external pulse oximeter device transmits the values to smriti and smriti receives the same via ble
03/02/2026
----------
Modified the document of the codes and its flow diagram, also explored about the camera integration part of SMRITI
06/02/2026
----------
Integrated the SMRITI code into BLE and searched and connected the device via a phone using BLE scan application
09/02/2026
----------
Prepared the document of firmware workflow of currently completed SMRITI and BLE integrated code and updated into the drive, Trying to communicate ameba with esp via ble
13/02/2026
----------
Completed the design of AMB82 with esp such that, ESP and AMB82 connected via BLE, ESP sends wifi credentials to AMB82 and ameba receives those credentials and connect to the hotspot . Then it will start video streaming , also it returns it ip to esp after wifi connection.
Need to modify and stable more
16/02/2026
----------
verified the ble communication between ameba and esp and sending credentials. Integrating the same into SMRITI
27/02/2026
----------
Working on the position of error detection in SMRITI and exploring about the TinyYOLO model, to check whether it is possible to do the detection mechanism using TinyYOLO model or not.
09/03/2026
----------
Working on the position detection system for SMRITI. As a part of it, currently i am working on measuring resistance using a variable resistor and reading the resistance from ADC of ESP32
17/03/2026
----------
Working on measuring the resistance of the nichrome wire in different steps. First i have done measuring resistance with pot and it is working, now i am working on different resistors for ensuring the measured value is correct or not
Testing the functioning of SMRITI for assembling it as a new device
