When the signal comes to trigger at pin 14 again. When the signal comes to trigger pin 14 again, causing the output pin 2, the LED1 is On and LED2 is OFF.īoth LEDs will turn on and off alternately. It causes the output to come out to pin 3, the LED1 glow but LED2 goes out. This circuit, I built for fun with my daughter. Q1, Q2: 2SC1815, 45V 0.1A, NPN TO-92 Transistor or equivalent The supply of this circuit is a typical 9V battery. This can be done by increasing the capacitor C2 to 330uF or 470uF as needed. Those who want it to blink longer after the switch is released. The LED does not conduct current according to its properties so current will flow through the resistors instead. While the voltage drop across the LED does not reach 1.7V. Look at both Resistors – 1K, they connect between the LEDs, to add improved circuit stability. And, it will be still bright until we press the switch again.įor the LEDs, we should use different colors such as RED and GREEN. Thus, the blinking rate of both LEDs will gradually slow down until stop the last time. But this amount of voltage will gradually decrease until it eventually runs out. Some currents remaining in the 220uF-Capacitor, it is discharged to supply bias voltage to the Base of both transistors. When we press switches, both transistors are biased correctly and Capacitors- 10uF 16V alternate charge and discharge.īoth LEDs will blink, ON-OFF(Light-Dark) alternately at high speed. So, I would like to summarize only the important things.
