The inverter I used is a Schmitt Trigger Inverter. The size of the resistor R1 and the capacitor C1 will, therefore, determine the blinking speed. The resistor R1 controls how much current that goes back to charge the capacitor on the input. To slow down the jumping back and forth, I’ve used a capacitor on the input of the inverter. So it will keep jumping between high and low. That means the input will be high again, and so on… Now that the input is low, the output will be high. But since the output is connected back to the input, the input will be low. This means that if there’s a high voltage on the input, the output will be low. In the circuit diagram you can see that the output of the inverter (U1) is connected back to the input with a resistor. A low voltage is a voltage close to zero volts. And vice versa.Ī high voltage is a voltage close to the supply voltage. If it gets a high voltage in, it gives a low voltage out. I designed the circuit around an inverter.Īn inverter is a logical component that outputs the opposite of what it gets in.

This circuit is from my Free Email Course on how to make a light blink. To solve this problem you can introduce a time-delay using a resistor and a capacitor. The problem with the circuit above is that it will switch so fast that you won’t actually see the light blink. When the relay coil has power, the switch will disconnect the power from the electromagnet and connect the power to the light bulb instead so that it will light up.īut when the relay no longer has power, it will switch back and turn off the power from the light bulb and give power back to the electromagnet again. To understand the circuit you need to understand how a relay works. In the above circuit you see a battery, a relay (in the red square) and a light bulb.
The easiest way to get a light to blink (or at least the easiest to understand) is the following: I’m going to show you three ways to build a blinking LED circuit using: Or you can make one using components like an inverter, a 555 Timer or a microcontroller.
There are several ways of making a blinking LED circuit. Three Different Ways To Build A Blinking LED Circuit The goal is to make a Light Emitting Diode (LED) blink. It was the first circuit I ever built, and it felt GREAT! It’s a simple electronic circuit that gives you a visual cue if it works. The blinking LED circuit is like the electronics version of the “Hello World”-program.
