Intro: Flashing Heart Using LEDs and 555 Timer
Yes I made it for someone special. It is a basic heart made of red LEDs. It has a flashing side too made by using 555 timer IC
Step 1: Components
I know some items may not be in the circuit but I assure you that both mine and this circuit works 100%
- Red Leds - 16 or more
- 330ohm resistors - 1
- Wyro Board (shown in pic)
- 555 Timer IC (any series)
- 10 uF Electrolytic Capacitor
- 100k Variable Resistor
- 10k Resistor
- 1 Push Button
- 9V Battery Holder Clip
- Soldering Equipment
- Breadboard just for testing the circuit(optional)
Step 2: Testing the Circuit on Breadboard
Now that you have got all components you test your circuit before soldering it all together.
I do it with all my projects and it saves both effort and time. Anyways I have attached circuit of bread board.
The push button is added after the +ve voltage for turning the heart on/off.
When your special person takes the gift he/she will press the push button for turning the circuit on/off.
It is simple and I have used breadboard just for testing. It is entirely up to you. This step is optional.
Step 3: Make a Heart
As you can see in the pics that I have just added leds to make a perfect Heart shape. I haven't started soldering or anything yet. It took me three tries to make a good shape heart. You cant make a more tall or fat heart, its up to you.
Hint:- I made it by counting the holes on wyro board.
Step 4: Solder the Ciruit Carefully
Now that you have tested your circuit on the breadboard, you can copy the same circuit here on wyro board. But be careful while soldering. Remember to first check every connection before applying the Hot tip of soldering iron.
Step 5: Fininshed!!!!
Now add a 9V Battery for power and your circuit is ready. I haven't made a box to put it in yet, but you do that else your special someone won't like it much :)
Step 6: What the Heart Does After Pressing the Push Button
This is a flasher circuit attached to the LED heart so it blinks very
fast then it slows down its rate. It continuously keeps on flashing and changing speed of flashing. Your friend will love it. Good Luck!
