The chicken farm automatic filling light circuit is composed of the power supply circuit, light control circuit, timing circuit and control implementation circuit, and it is shown in Figure 4-10. Power supply circuit is composed of the power switch S, power transformer T, rectifier diodes VD1-VD4, filter capacitors Cl, C2, and three-terminal voltage regulator integrated circuit ICI. Light control circuit is composed of the photosensitive resistor RG, potentiometer RPl, resistor Rl, capacitor C3 and the time-base integrated circuit IC2. Timing circuit is composed of the timer integrated circuit IC3, resistors R2, R7, potentiometer RP2, capacitor C5 and diode VD5. Rl-R7 select the 1/4W metal film resistors or carbon film resistors.
