Is it possible to connect Arduino esp01s max30100 and oled for single project... I'm unable to use max30100 and oled while using esp01s
There are many OLED displays that use I2C. A quick Google tells me there are MAX30100 boards with I2C ports as well.
This Instructable shows how to set up I2C on an ESP-01.
Good luck.

Here I'm using esp01s as a wifi module and Arduino nano as a controller.. max30100 OLED 0.96 inch , Lm35, water level sensors are the inputs.. it's working fine with Arduino+esp01s+Lm35+water level sensor.. but when I tried to include OLED it' unable initiate (Failure in serial monitor). But for the same circuit i tried another simple OLED code and it's working properly.. so I can believe there's no problem in connection... and if I tried MAX30100 it's LED glowing but it's not reading any values( BPM 0 & SP02 0 In serial monitor) .
I felt esp01s is the reason for it . But I don't know how to solve it.. because esp it self major part of the device.
all the components could be overloading the nano power regulator
in particular when the ESP-01 transmits there canbe a peak in current consumption
be careful the nano uses 5V logic the ESP-01 3.3V
use a potential divider or bi-directional level converter on any 5V signals from the nano, e.g. the nano serial TX to ESP-01 Rx line

From what you have I believe you need an external power supply. There are two simple rules to follow for power.
The Crispy Critter Rules:
Rule #1. A Power Supply the Arduino is NOT!
Rule #2. Never Connect Anything Inductive to an Arduino!
Violating these rules tends to make crispy critters out of Arduinos.
