The next project describes two LEDs that flash alternately over a fixed interval of time. So again we're using a 555 timer IC here, in astable mode. The resistor/capacitor values are such that the output on pin 3 switches between low to high. You may see in the schematic that the positive terminal of one of the LEDs is connected to pin 3 via a resistor while the negative terminal of the second LED is also connected to the same pin. Thus, when the output is 1 (High), LED 1 glows and when the output is 0 (Low), LED 2 glows. The cycle continues.
Connect all the components as per the layout. At last, connect a power supply and check if it works. You have to be very accurate with the connections. Try changing the value of the 47K resistor to random. Decreasing the value would increase the flashing speed.
Difficulty: Easy
Parts Used:
1x NE555 IC
1x 10uF Capacitor
2x LEDs (any color)
2x 100 ohm Resistors
1x 47K Resistor
