Abstract: Light-emitting diodes (LEDs) have been deployed for various applications in our daily lives. Similarly, image sensors or cameras integrated into mobile phones have become common. Hence, ...

You might think that CD players and DVD players have had their run, but as it turns out, they are absolute goldmines for DIY projects. Pop one open and you'll find stepper motors, laser assemblies, ...

Today’s IR-based remote controls have little resemblance to their predecessors; it took the convergence of unrelated advances to get us here. We take the ubiquitous infrared-based (IR) remote control ...

As mentioned in the Raspberry Pi Pico 2 article, third-party RP2350 boards are already available, and one of them is the MOTION 2350 Pro board from Cytron designed for robotics and motor control. The ...

A desk lamp is an essential item you’ll need in your home office, bedroom, or dorm room to prevent eye strain and allow you to keep working and reading long after the sun has set. But task lamps, as ...

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

elektorjuly/august 1983 65 o n/off with a single push button A very useful function expressed in a 1 simple circuit that is suitable for many applications. Basically the out- put of the Schmitt ...

As shown in the block diagram above, the Coin acceptor module acts as the input device which gives the signal to Arduino when it detects a valid Coin inserted within it. Arduino receives the signal ...

The multitasking has led the computers to a revolution where one or more programs can run simultaneously which increases efficiency, flexibility, adaptability and productivity. In embedded systems, ...

We build this weather monitoring system using Arduino that provides information such as temperature and humidity on a color touch-screen display. It can also control the temperature through the ...

Some may ask why you’d want to program a Cortex-M microcontroller like the STM32 series using nothing but the ARM toolchain and the ST Microelectronics-provided datasheet and reference manual. If your ...
