Scott @ swharden.com show us how to interface an analog signal to a microcontroller that doesn't have an ADC. I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method...

Intended for tasks such as monitoring IoT networks from a handheld device, Texas Instruments' latest series of microcontrollers are single-chip Sub-1 GHz plus Bluetooth low energy ICs. By Graham Prophet @ www.edn-europe.com As part of TI’s pin-to-pin and software...

The Tiny Lisp Computer is a self-contained computer programmed in Lisp. Some programming examples are included in the author's website. This article describes a self-contained computer with its own display and keyboard, based on an ATmega328, that you can program in Lisp. You can use...

It has been about one year since the announcement of ESP32 SoC and the beginning of its beta testing for some developers. Last Month we covered the release of ESP-WROOM-32 module datasheet,  which promised that “New SDK features, tutorials and example applications will be...

Jesus @ jechavarria.com pointed us to his latest project, a portable temp, humidity and ambient light datalogger. Hi all! I’m continuing here with the last board I design and now I’m continuing testing. It’s a battery-powered small datalogger based on a PIC18F2620...

Low-cost, open-source "sip-and-puff" interface to enable new methods of expression for people with and without limited mobility. by Jason Webb: Commercial sip and puff devices have been available for quite some time but are generally prohibitively expensive, highly specialized,...

SunDuino is a Single Board Computer with integrated Battery Charger, Voltage Regulators, I2C, Digital and Analog IO. It's main benefit is that it can run a compiled C app for years on a small battery or forever using built in solar charger. A background RTOS provides SLEEP...

If your application needs a controller with display interface and a network connectivity, then you need to think about using 4Duino from 4D Systems, a 2.4" TFT LCD IoT display module. 4Duino key features 4Duino has ATmega32U4, a 8-bit MCU from Atmel, which is the same...
