Circuit Monday #4 555 flashing led

Welcome to Circuit Monday this weeks   circuit is a using a led to make an led flash .
this was built on the prototyping board that I made in yesterdays Project Day #3

Parts needed 

1 X 555timer
1x capacitor
1X resistor 
1Xled

Step 1 

place 555timer on the board 


Step 2 

connect pin 2 of the 555 to pin 6 with a jumper wire

Step 3

connect pin one to - rail of the board

Step 4 

Connect pin 4 to the + rail o

Step 5 

connect pin 8 to  the + rail

Step 6

connect pin 6 and pin 7 with a jumper and 

Step 7

connect the resistor to pin 7 and the + rail

Step 8

connect the capacitor to pin1 and pin2 making sure the negative side is in pin 1 

Step 9

connect a jumper wire to pin 3 and a empty row on the board 

Step 10

connect the cathode of the led to the same row as the jumper wire coming from pin 3 

Step 11

connect the anode side of the led to the + rail  and power the circuit 
the led will flash every few moments depending on the values of the capacitor and resistor 

Fritzing layouts

here is the layout I made on Fritzing which is really useful software if you haven't checked it out I suggest you take a look.


thanks for reading see you tomorrow for Training Tuesday
