It worked fine with just one LED, but when I set a resistance value to flow 40mA to the LED, I was able to turn it on from off, but I couldn't turn it off from on.
El sol se pone como un espectáculo de fuego Y contigo me siento como en casa Tu risa, es como mi canción favorita Voy a cantarlo toda la noche Cada momento contigo se siente bien En tus ojos, las estrellas brillan intensamente Bajo el cielo del campo, te sientes tan viva Hola niña, tu sonrisa es una melodía, como una dulce sinfonía Cada toque, tu amor es dorado El amor es nuestra perfecta armonía El amor somos solo tu y yo Querido vamos a bailar hasta la luz de la mañana Debajo de estos cielos infinitos Tu corazón late a un ritmo tan verdadero Estoy perdido en cada latido contigo En este mundo somos tu y yo El amor es nuestra perfecta armonía El amor somos solo tu y yo El amor es nuestra perfecta armonía El amor somos solo tu y yo El amor es nuestra perfecta armonía El amor somos solo tu y yo
This circuit is featured on page 48 of the Engineer's Notebook II: A Handbook Of Integrated Circuit Applications by Forrest Mims (1982). It is not a latch but a countdown timer and shouldn't be relied upon to stay in the 'On' state indefinitely. Leave it with the LED on for a few minutes and you will see that it turns off by itself without the button being pressed.
Hello, greetings. I'm from Indonesia. I want to ask how many volts the LED is? and for the load on the LED, for example if I replace it with a relay, is that possible? because I will use it on 220v AC voltage.
Good sound, would you add the numbers of the pinouts for the chip? The images I have seen, in data sheets, show the plus and negative markings opposite to those on your schematic diagram. Best regards.
