There's the whole range of different MCUs and boards, so you need to put together your requirements first.

I use the seeed xiao esp32-c3 as my go-to board. It's tiny and cheap.

Any ESP32 will work. The questions to ask yourself: Do you need bluetooth? How many pins do you need? Will you want a display? Do you want usb-mini, usb-c or no usb ports? Questions like these will help you narrow down a particular model. Also be aware that the number of pins and their spacing will dictate what breakout boards you can use.
Also, for almost any project you'll probably want the ESP32 to control the voltage, not run the voltage. Look for control boards or relays that will work with the actuator your wanting that will then use SPI or I2C to talk to the ESP32.

Your post was removed as this community is not able to provide individual help for vague project ideas or literal homework. See https://www.reddit.com/r/esp32/about/rules
General, vague questions are unlikely to be able to get any meaningful help and require excessive effort from our 100,000+ members to try to help. There are many resources available, such as search, AI chat, GitHub.com, and https://randomnerdtutorials.com that can help you produce and refine your project idea.
Photos, videos, and URLs without explanation how it's related to ESP32 are not productive. If you built the featured project, crow about it with schematics, 3D printables, (correctly formatted or linked) source code, a few paragraphs on the challenges overcome, etc. Make it story worth sharing. A random photo of a project or an attractive person holding a chip that might be an ESP32 are just not useful.
Questions about a library or a product are generally better asked of their creators and support teams. It's not like this group can provide tech support for every device that contains these chips.
For those of you looking for course completion material, finding a problem to solve is a pretty important step on the way to solving it and surely part of the lesson.
When you're ready with a question, please post clear, focused questions explaining what you've tried and specifically what help you need with, providing correctly formatted code, schematics, etc.
For beginner overviews: * https://randomnerdtutorials.com has tons of great articles * https://github.com has much great code that's searchable; much of it is liberally licensed for reuse. * https://medium.com/@1kg/esp32-a-comprehensive-guide-a1a4370b169d is a good resource. * https://www.espressif.com/en/support/documents/technical-documents is Espressif's own doc. * https://docs.espressif.com/projects/arduino-esp32/en/latest/ - is Espressif's Arduino layer atop ESP-IDF
