I recently finished a fun project where I built my very own low-cost Bluetooth joystick controller for gaming using an ESP32 board! I put a lot of effort into soldering the components onto a PCB ...

We’ve been keeping up with the ongoing software developed for the ESP32 WiFi chip, and that means a lot of flashing, hooking up random wires, and rebooting. Along the way, we stumbled on an Easter egg ...

The ESP32 Internet Radio from Poland-based maker, The MicroMaker, is a simple hardware kit that combines the LilyGo T-Display S3 Development board with an I2S audio breakout module and other ...

ESP32 microcontrollers, known for their versatility in IoT and smart home projects, also support digital audio via their I2S interface. In the first part of this series, we explore an audio-focused ...

Espressif Systems has formally announced the ESP32-H4 low-power dual-core 32-bit RISC-V wireless microcontroller with support for 802.15.4 and Bluetooth 5.4 LE portfolio after having unveiled it at ...

Just because a microcontroller doesn’t have a dedicated video peripheral doesn’t mean it cannot output a video signal. This is demonstrated once again, this time on the ESP32 by [aquaticus] with a ...

The last two supports WS2812 RGB and SK6812 RGBW LEDs. The software of all clocks supports a Bluetooth connection to control the clock and as backup a rotary encoder, an accurate DS3231 RTC and a LDR ...

ESP32 modules often have “integrated antennas” printed on the PCBs. But, at times, you might need improved Wi-Fi range. A solution can be an external antenna, but not every module has a socket for ...

Drones have rapidly evolved from niche hobbies to versatile tools with a wide range of applications, from photography to agriculture or even for defense and military purposes. Building a DIY drone ...
