An RC aircraft can be expensive. If you plan to chase other RC aircraft on a path of mutual destruction, keep costs down with a disposable flying platform.

I had the idea of creating a night flyer out of one of my R/C combat planes. What if it could be done quickly using servo leads and be easily serviceable?

Radio-Controlled onboard power systems used to be quite basic, but with the introduction of electric drive motors and other power demands, things have changed.

How to use a series of capacitors and resistors to convert a square wave to a sine-like wave that results in a comfortable audio signal that sounds natural.

What are flip-flops and how do they work? Find out in this blog.

A working example of how RC timing functions in a DC circuit.

The founder of DigiKey started the company by selling a Morse code generator. See its original design alongside an updated version you can build.

Hydraulic and pneumatic actuators offer power and speed in repetitive use mechanisms. Each type offers distinct advantages and features.

Covering all combinations of button presses with if/then statements could generate hundreds of lines of code. Implementing bitwise logic minimizes code.

Make a custom breakout board for FadeCandy using DigiKey’s PCB Builder tool.

Mainstay 5 V logic is joined by ever lower voltage standards like 3.3 V, 2.5 V, 1.8 V and lower, resulting in the need for mismatched systems to communicate.

Förebyggande underhåll är en vanlig metodik för att förhindra att äldre maskiner drabbas av driftavbrott, men det kan ha ett högt pris. Omron har lösningar för att minska kostnaden.

Digital panel meters are available in LED or LCD configurations with a wide array of text colors and backlighting if needed.

When a project’s physical size goes beyond using traditional project boxes and enclosures, custom extruded aluminum frames could be a good choice.

The benefits of logic and small signal switching using MOSFETs over other traditional transistor technologies.

Sedan programmering blev en möjlighet för gemene man, finns risk för att enkel men användbar kod förbises eller helt glöms bort – exempelvis direct port manipulation (DPM).

SparkFun Teensy 3.5 har tillräckliga digitala brytare för att hantera tre borstlösa DC (BLDC) hallsensorsignalingångar och leda displaydata dit de behövs.

Digilent AD2 kan hjälpa till att visualisera utsignalerna från hall-effektsensorerna för att hjälpa till att förstå och behandla signaler under projektutvecklingen.

Vissa BLDC-motorer är utrustade med tre interna hall-effektsensorer som ger återkoppling till externa kretsar för precis kontroll av magnetspolarna i statorn.

The Sweep function is a common intro to MCU servo motor control which is needed to achieve the full range of positions on a servo motor.
