The circuit is consists of twoNand gates(74HC00 IC) forming aSR flip flop. As you can see in the circuit diagram whenever the toggle switches to the A side the output logic gets ‘HIGH’. Here, we have used an oscilloscope to detect the bouncing. And, as you can see in...
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 microcontroller is an integrated circuit (IC) which is small, low cost and self contained computer designed to handle a specific task in embedded systems. In simple words, a microcontroller (MCU or Microcontroller Unit) is a small computer integrated in to a single chip. We can also explain...
This schematic shows an astable 555 timer IC pulsing an LED on and off: 555 timer uses R1, R2 and C1 to generate a clock signal. Transistor Q1 amplifies the pulse to drive LED D1. R3 limits LED current. Voltage Divider Circuit
Comparisons were drawn between the development of television in the 20th century and the diffusion of printing in the 15th and 16th centuries. Yet much had happened (61) As was discussed before, it w...
