"Traditionally, the peri-LC has been thought of as sort of a 'dimmer switch' for the ... "The peri-LC cells apparently act like a radio gain circuit that can dial up or down the strength of ...

“You could’ve done that with a 555 timer.” But what if all you have on hand is an ESP8266? [TechColab] needed to control a solenoid valve with a short pulse via a solid-state relay (SSR) but ...

Appliances fail, but that doesn’t mean it’s the end for them. This impressive hack from [solopilot] shows the results possible when not just fixing but also improving upon its original form.

It sends that SMS through its mobile network. This makes the Arduino send SMS, even though it doesn't use any GSM modules at all. Here, to send SMS alerts, I am using the Circuit Digest Cloud SMS APIs ...

RECOM has released power modules featuring an ultra-wide input voltage range of 18 to 264 VAC and 18 to 375 VDC. Designed with a standard 1.5 by 2-inch footprint, these modules deliver fully regulated ...

This paper proposes a dimmer circuit that is suitable for incandescent bulbs, CFLs and LEDs. Different kinds of lighting devices are studied and tested with AC and DC sources. The proposed dimmer ...

At the heart of the door monitoring circuit, there is an M95 GSM-module MOD1 with antenna and SIM-card holder SIM1. The resistors R15 through R17, the diode array D7 and the capacitors C19 through C22 ...

This library provides a simple device independent interface for interacting with Adafruit IO using Arduino. It allows you to switch between WiFi (ESP8266, ESP32, ESP32-S2, ESP32-S3, ESP32-C3, RP2040, ...
