this was built on the prototyping board that I made in yesterdays Project Day #3
Parts needed
1 X 555timer
1X resistor
1Xled
Step 1
place 555timer on the board
Step 2
connect pin 2 of the 555 to pin 6 with a jumper wireStep 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
