What is PWM (Pulse Width Modulation)? PWM stands for Pulse Width Modulation; we will get into the reason for such a name later. But, for now understand PWM as a type of signal which can be produced from a digital IC such as microcontroller or 555 timer. The signal thus produced will ...
A microprocessor is similar to our human brain, it can be trained to do anything. It can be programmed to do anything we want based on it’s instruction set and capabilities. Sometimes solutions are very complex, circuits also becomes very complex if we try to solve it without programming....
Instagram is revamping its profile layout by moving Story Highlights to their own dedicated tab. Previously displayed as circular icons (or “pogs”) above the profile grid, Story Highlights will now reside in a separate section marked by a heart-shaped icon. This change aims to declutter profil...
One more point to note here is the exception number. The exception number is used by ARM Cortex M CPU to index into the location of the interrupt vector table. The vector table and interrupt service routines/exception handlers are defined inside the startup file of a microcontroller. The star...
A substitution, based on an electrical port, is now supported when that substitution is requested inside the #BEGIN/#ENDBEGIN directive block (#6332). Polygraph hotkeys (ex. ‘y’) now function properly (#6577). Virtual wires will now properly identify and display feedback loop signals (#...

In this circuit, the 555 timer circuit constitutes a voltage-controlled oscillator. The control terminal cooperates with the field effect tube to realize the large-scale adjustment of the duty cycle. The circuit is shown in the figure: In the circuit, the 555 timer, resistors R1, R2, capacito...
What is inside a pulse generator? Pulse generators consist ofa battery, circuitry, can, antenna, reed switch, and connectors. Lithium-iodine is the most commonly used power source for today's pacemakers. Circuitry contains microprocessors to control sensing, output, telemetry, and diagnostic circuits...
This is in comparison to a straight if statement, where the unwrapped value would be available only inside the if block, like this: if let unwrappedName = userName { print("Your username is \(unwrappedName)") } else { return } // this won't work – unwrappedName doesn't exist here!
How To Design A Guard Ring Implementing a guard ring in your design is not rocket science. You’ll need to place a copper trace around the input pin of the op-amp. It is important to route the ring to either VDD or Ground for it to be effective. ...
