One of the fun things about “old school” computers is that it was fairly easy to get kids into programming them. The old Basic interpreters were pretty forgiving, and you could do some clever things ...

Learn how to turn old appliances into smart, Wi-Fi-enabled devices with ESP8266 and ESPHome. DIY automation made simple for your home.

Many microcontrollers have built-in ADCs (analog-to-digital converters), which means you can use a single device to both digitize analog signals and manipulate the results. Once the ADC digitizes a ...

Voice assistants and smartphones are often the go-to interfaces for modern smart home systems. However, if you fancy more direct physical controls, you can go that route as well. To that end, ...

This MCU-based circuit converts sensor outputs, which are often voltage, into a standard current signal, thus avoiding noise and loss when sending over long lines. When taking measurements from analog ...

As computer systems become more and more ubiquitous in everyday items, the workings of those items will require some sort of digital controlling. Controllers that once handled large mechanical systems ...

A typical PC-based test system may include analog and digital I/O cards and one or more communications buses that let you control external instruments. Budget restrictions, however, may force you to ...

In its introductory blog post, the company explains that today’s Raspberry Pis are already often used alongside a smaller microcontroller: The Raspberry Pi takes care of heavyweight computation, ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...
