Figure shows a variation on a sine wave oscillator, it uses just two transistors and a single variable resistor to set the frequency...

Arduino is partnering with chip startup Axelera to bring machine learning out of the cloud and into IoT devices based on its Pro hardware...

Driving LEDs at a regulated current from low supply voltages can be difficult because minimal overhead voltage is available for control circuits. A current-mirror architecture is suitable but usually works only with ICs with well-matched transistors...

This design idea is centered on the humble on/off/on toggle switch, which is great for selecting something/nothing/something else, but can be frustrating when three active options are needed...

Filtering occurs frequently in the analog world. Unfortunately, in the digital world, engineers apply it mainly to the DSPs and not to the small 8-bit microcontrollers that designers commonly use...

This dummy-load circuit has been in use at Maxim for more than 10 years. It's useful for testing power supplies and power amplifiers as well as drivers for LEDs, relays, and solenoids...

I needed a simple mist maker/humidifier for a project that I was working on. I found lots of ideas on the internet, but they all lacked in one area or another, so I decided to design one...

Variable regulated power supplies are handy tools found on well-equipped electronics lab benches. The symmetrical varieties that produce equal voltage outputs of opposite polarity, are even more so...

The ubiquitous variable resistance circuit network shown in Figure… But a sticky question remains: What if the polarity of the VA – VB differential is subject to reversal...

We often say that logic devices are the glue to every electronics design, but they are often the last parts that you might think about when choosing components for a system...
