First-Time Project with ESP32 – Need Help Choosing Components

[Antonx]

Hi everyone,
I’m a complete beginner in electronics and robotics, and I’m trying to build my very first project using an ESP32. I have some ideas about what I want to do, but I’m not sure if the components I’m choosing are suitable.

Here’s what I’m planning:
Motors & Wheels: To move a small robot around.
Motor Driver: L298N for controlling the motors.

Sensors:
Ultrasonic sensor HC-SR04 for obstacle detection.
IR sensors / bump sensors for detecting edges or collisions.
PIR sensor for detecting humans in the room.
Power: LiPo battery 7.4V with a step-down module to feed the ESP32.
Other: Breadboard and jumper wires.

I would really appreciate any advice on:
Whether these components are compatible with ESP32 and each other.
If the battery and step-down setup is safe and sufficient.
Any suggestions for improvements, or if I’m missing something important.

I also need help to find:
bump sensors
LiPo battery 7.4V with a step-down module to feed the ESP32

I’m completely new, so any guidance or tips would be amazing. Thank you so much for your help!

Whether these components are compatible with ESP32 and each other.

This depends on the availability of libraries for these components for the development environment you want to use, e.G. ESP-IDF or Arduino.
I would start with an ESP32 Robot Starter Kit. These are widely available and should contain software examples. And with an ESP32 with enough IO-pins it should be easy to enhance it.
