Here''s how you blink an led with just an led, capacitor, transistor and two resistors. This post is a complement to Dick Cappel''s "Simplest LED Flasher Circuit" post. I''ve added a Fritzing diagram and some high-res photos and video so that you can quickly build the circuit. Most of the other videos online are from a very long time ago and are mostly out of focus.
While either of the capacitors is charged, the base voltage of the transistor is negative, thus the transistor remains OFF. The frequency of this is related to the time needed for the capacitor to discharge (when it is connected in reverse polarity to ground via a resistor - e.g. C1-R2). LED Flasher circuits usually work on the same principle.
By connecting an LED to the output of the IC, we can create a flashing effect. To build the LED flashing circuit, you will need the following components: To build the circuit, follow these steps: Insert the 555 timer IC into the breadboard. Connect a 1kΩ resistor between pins 7 of IC and 5V supply +Ve Terminal.
[simple-blinking-led Connect transistor’s emitter in between the 1k resistor and the capacitor’s positive lead. Connect the collector a couple of holes over. Don’t connect the base. Hold the transistor with the flat side facing you. The pin on the left is the emitter, the pin on the right is the collector, the pin in the middle is the base.
Use wire links to connect the base (middle pin) of each transistor to the negative lead of each opposite capacitor. The completed circuit is shown in the image below. Power up the dual LED flasher circuit using a 9V battery. Connect the black negative lead of the 9V battery clip to the bottom horizontal breadboard rail.
A very simple circuit that you can build to blink or flash LEDs. The circuit is built using transistors, resistors, capacitors, and LEDs. Of course you will need a breadboard, wire jumpers, and a power source. The parts list includes: Let's get started:
Connect one wire of the second resistor to the collector of transistor 2. The the other resistor wire then connects to the positive wire of the second LED. The negative wire of the LED is then connected to ground. The last step is to supply power and watch the LEDs blink. I use a 9 volt battery and it worked fine.

Do you want to build a circuit that blinks a light? This inverter-based circuit is simple, and it''s small enough to fit on a breadboard. The circuit uses standard basic electronic components and you can build it even if you have never built anything before. Check out the full build instructions in the video below:
Connect the Three capacitors to the circuit. Connect the positive lead of the first capacitor to the collector of transistor 1 Next connect the negative lead of the same capacitor to the emitter of transistor 1.
up to now my Guitar worked fine. Just today as I tried to connect it seems to connect as Controller No. 2 but the other lights keep flashing and nothing works. USB connector is unlikely because my other Guitar connects fine and the Broken one doesn''t work with my Second connector as well. So I assume the Receiver of the Guitar.
Make sure it is oriented correctly to avoid damage. Next, connect Pin 1 to the bottom row of the breadboard (ground) using a short jump wire. Connect Pin 8 to the top row (VCC) using another jump wire. Then, connect Pin 4 to Pin 8 using a third jump wire. Connect the positive leg of capacitor C1 to Pin 2 and the negative leg to the ground ...

Hi everyone, I have some electronic motion switches that when we switched from incandescent lamps to LED lamps, there is not enough of a load to stop the triac in the switch from leaking current when it is off and keep it stable when it is on. I done want to put a dummy load in the circuit...
I''ve been trying to devise a very simple circuit to confirm in my mind how capacitors work. The goal is to make an LED flash on and off using a capacitor or two and one or more transistors. I''ve tried various things but I''m getting nowhere fast. I''ve seen circuits online but they tend to involve two LEDs, inductors or other strange setups.

The 10uF capacitor determines the flashing frequency. The 2.2KΩ resistor limits the operating current of the LED. So let us get to work… What do we need? Just a light source with a battery that lasts a long time, a lightweight housing that floats, is tight and carries the electronics. Just should not be that big.

When the button is pressed down, closing the circuit, the battery does two jobs: it charges the capacitor up with voltage and it gives power to the LED, lighting it. Once the battery is on for enough time for the capacitor to be fully charged up to 9 volts, the capacitor cannot retain any more charge. This happens in a matter of seconds. The ...
