Every diabetic knows that one of the major burdens of the disease is managing supplies. From insulin to alcohol wipes, diabetes is a resource-intensive disease, and running out of anything has the potential for disaster. This is especially true for glucose test trips, the little electrochemical dongles that plug into a meter and read the […]

Like many of you, we’ve been keeping a close eye on the CH32 family of RISC-V microcontrollers from WCH Electronics. You can get the CH32V003, featuring 2 kB RAM and 16 kB of flash for under fifteen cents, and the higher-end models include impressive features like onboard Ethernet. But while the hardware is definitely interesting,

The T-Display AMOLED Touch ESP32 is an advanced version of the well-known ESP32 board, now equipped with a touch interface. This addition transforms the board into a more interactive platform, suitable for a wide range of applications. T-Display-S3 AMOLED is a display screen module with a 1.91″ diagonal screen, based on our previous S3 module, we have

The ESP32 has been a go-to microcontroller platform for a while now, thanks to its versatile capabilities, integrated Wi-Fi and Bluetooth connectivity, and low power consumption. It’s ideal for a wide range of projects especially those revolving around IoT, partially because of all of the libraries and tools available for it now. The latest tool

There are many ways to lock a door. You could use a keypad, an RFID card, a fingerprint or retina scan, Wi-Fi, Bluetooth, the list goes on. You could even use a regular old metal key. But none of these may be as secure as [mircemk]’s Arduino-based door lock that employs a smartphone’s flashlight as a
FLASHLIGHT DOOR LOCK IS A BRIGHT IDEA Continue Reading
The equipment used in professional radio and TV studios is both extremely high quality and very expensive indeed, and thus out of the reach of an experimenter. Happily as studios are refurbished there’s a steady supply of second-hand equipment which can be surprisingly cheap, but as [Nathan] found out with a Quartz audio router, comes

Adafruit’s new MEMENTO – Bare Board Camera module is powered by the ESP32-S3 and can be programmed with CircuitPython or Arduino. The module includes a camera with an OV5640 sensor which features auto-focus capabilities and the board includes a 1.54″ 240×240 Color TFT to display the images. Previously we have covered many ESP32-based camera modules
VFD displays are beloved for their eerie glow that sits somewhere just off what you’d call blue. [mircemk] used one of these displays to create an old-school VU meter that looks straight out of a 1970s laboratory. The build uses an Arduino Nano as the brains of the operation, which uses its analog inputs to process
VU METER BUILT WITH NEAT GRAPHICAL VFD DISPLAY Continue Reading
[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Arduino code showing how handy this can be for battery-powered projects. The classical way to measure a system’s voltage is to connect one of your MCU’s
