Multiprotocol modules can be flashed with a precompiled firmware file (Option 1 and 2) or you can compile and upload your customized firmware using the Arduino IDE (Option 3). These instructions are ...

M5Stamp C3U is an update of the M5Stamp C3 RISC-V IoT module with heat-resistant cover, support for WiFi 4 and Bluetooth 5.0, that does without CH9102 USB to TTL chip, relying instead on the internal ...

Chen Liang (陳亮) has found an interesting use case for the Espressif ESP32-C5: a dual-band Wi-Fi analyzer showing the signal ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

As part of another Arduino project, using an HC-SR04 ultrasonic sensor to monitor a vehicle parking in a garage, I needed information on a vehicle's velocity as a function of position pulling into a ...

The MPU6050 module has a total of 8 pins, of which at least 4 pins are necessary for the interfacing. VCC provides power for the module. Connect to the 5V pin of the Arduino. GND Ground is connected ...

The world of littleBits (the “not-a-toy” toy that I reaaaally wish existed when I was younger) just got a little bit bigger: it can now play friendly with Arduino. If you’re not familiar with ...

The Joystick module is similar to analog joysticks found in gamepads. It is made by mounting two potentiometers at a 90 degrees angle. The potentiometers are connected to a short stick centered by ...

“You can’t put new wine in old bottles” – so the saying goes. But you would if you’re a hacker stuck with a radio built in 2005, which looked like it was put together using technology from 1975.
