Can we make timer circuit using transistor?
Can we make timer circuit using transistor? When the circuit is powered by a 9V battery, the LED switches on. A switch (or link on the breadboard) is closed to start the timer causing the LED to switch off for a time period....Components.Qty1Part470 ohm resistor (yellow - violet - brown)DesignatorR1Notes1/4W, 5% or betterTypeResistors How does a transistor timer circuit work? The timer works on the capacitor “C” Resistor R1, R2 and emitter network, this network is arrange in such way that they provides forward bias voltage to the transistor base terminal (break over voltage). The timer duration changes by changing...
