ESP32 boards are incredibly versatile tools.You can use them for a huge range of purposes, and they can also be an extremely cheap way to help you get started in a new creative tech hobby.Electronic music Build simple synthesizers and drum machines on an ESP32 Have you always dreamed of having your own recording studio full of old synthesizers connected by a mess of cables? If so, the space and cost may have been enough to put you off.
With an ESP32, neither of those things is an issue.You can use an ESP32 to build tiny synthesizers or drum machines for just a few dollars.The ESP32 can generate and process audio, and adding buttons, rotary encoders, or touch inputs can give you physical controls.
An external I2S DAC can give you much better audio output, too.With an ESP32, you can build a simple synthesizer, a step sequencer, a MIDI controller, a drum machine, and more.You can gradually add more to your setup as you go, until you have that mess of synthesizers in a much tinier form.
Related Building Cyberdecks Is the Geek Hobby You Need to Check Out When you feel like you're going to have a snow crash, make sure you have your cyberdeck.Posts By Sydney Butler Retro game development Design and build your own 8-bit games Close An ESP32 can be surprisingly capable of running games.It's powerful enough to drive a small display, read physical controls, and handle the relatively simple graphics and sound of classic 8-bit games.
Playing classic games is fun, but with an ESP32, you can develop your own games, too.You can start off simply with a basic Pong or Snake game and work your way up to far more complex games.If you want to cheat, you can even use an AI chatbot to do the hard work for you while you come up with the ideas.
LED art Animated light sculptures, pixel art, and more Addressable LEDs are light strips or matrices in which you can control individual LEDs or groups of LEDs, allowing you to create impressive effects.It turns a strip of LEDs from something you can use to light up your kitchen cabinets in purple to something you can use to create genuine art.An LED matrix, for example, allows you to create pixel art and even pixel animations.
An ESP32 is a great way to get started, because WLED dramatically lowers the barrier.You can flash WLED to an ESP32, connect the LEDs, and start creating your masterpieces without writing a single line of code.You can create wall art or use LEDs to light up physical artworks, use microphones to make installations that react to sound or music, or even have your creations react to people approaching.
Robotics Get in quick before Elon Musk According to some tech moguls, autonomous robots are going to proliferate to the point where there are more robots than people, and could eventually become more productive than all humanity combined.So far, however, the reality is that some of the most impressive robot demonstrations have turned out to rely on people controlling the robots remotely.If you want to get in before robots really make it big, an ESP32 is a cheap way to dip your toe in the water.
While you're not going to build a humanoid robot that follows the Three Laws of Robotics from an ESP32, there's still a lot you can do.An ESP32 combined with a motor driver, motors, and a battery is enough to build a simple rover.Once it's driving, you can work on adding ultrasonic distance detection to avoid obstacles, and you're well on your way to having your own robot army.
You can then expand into robot arms, animatronics, and even walking robots.Astrophotography An ESP32 can't photograph the Crab Nebula, but it can help Astrophotography can be an expensive hobby, and before you get too excited, you're not going to be able to take stunning deep-space photographs with an $8 ESP32 and a camera module.However, an ESP32 can help you build some useful astrophotography accessories.
For example, you can use an ESP32 to build a DIY star tracker.When you're taking a long-exposure photograph of a distant object, the pesky rotation of the Earth means that the object will appear to move across the sky.With an ESP32 and a stepper motor, you can build a mount that tracks the object as the Earth rotates.
You can build other accessories, too, such as intervalometers, motorized focusers, dew-heater controllers, and more.Capturing stunning images using equipment you've built yourself can be even more satisfying.Seeed Studio XIAO ESP32C3 Brand Seeed Studio The Seeed Studio XIAO ESP32-C3 is the perfect budget-friendly microcontroller for smart home projects.
With Wi-Fi and Bluetooth built-in, it also features a super deep sleep mode for low power usage when it isn't doing anything.The compact size makes this ideal for building smart home projects, and ESPHome allows it to easily integrate into Home Assistant.$5 at Seeed Studio $10 at Amazon Expand Collapse An ESP32 can't solve one problem While an ESP32 can help jump-start a new tech hobby, it can't solve perhaps the biggest issue that plagues all hobbies: upgraditis.
Unfortunately, there's nothing that you can build with an ESP32 that will stop you from wanting even more expensive equipment, no matter how much you spend.
