The eggs automatic incubator circuit is composed of the power supply circuit, temperature / ventilation control circuit, automatic egg turning control circuit and temperature indication circuit, and it is shown in Figure 3. Power supply circuit is composed of the power switch S3, power transformer T, bridge rectifier UR and capacitors C2 ~ C4, current limiting resistor R12 and zener diode VS. R1 ~ R17 use 1/4W carbon film resistors or metal film resistors. RP1 ~ BP5 use high-quality synthetic membrane potentiometers or multi-turn potentiometers; RP6 uses the organic solid potentiometer. C1, C4 ~ C6 and C8 select monolithic capacitors.
