Design an electronic circuit that can be assembled at home using discrete components, which performs the following function: The circuit will detect the presence of a flame in a gas burner using the principle of flame ionization detection. When a flame is detected, it will turn on a green LED; when no flame/combustion is present, it will turn the LED off. Include a signal output so that the signal can be fed into an Arduino Nano in a subsequent stage. The circuit should be powered by the 220-volt AC residential mains supply, preferably using a traditional iron-core transformer. Provide the circuit design as a high-resolution image.

240гA0 cal devices? REVERSING-JOG CONTACTOR CIRCUIT Objective To design, connect and test a DOL magnetic contactor circuit which provides forward, reverse and jogging operation of a 415 volt, three phase SCi motor and incorporates limit switches. Equipment Two three phase magnetic contactors. One thermal overload relay. One emergency stop One push-button station which includes reversing and jogging buttons. One three phase 415 volt SCI motor - 2kW or similar. Multimeter. Three phase lead and 4mm shielded banana plug connecting leads. 415 volt, 2 kW three phase squirrel cage induction motor is to be used to operate a lifting hoist motor. The motor direction is to be controlled by magnetic contactors - one labelled UP and the other labelled DOWN. The contactors and other control equipment are located in a metallic enclosure which has a push-button controller to allow the following functions: UP, JOG UP, STOP, JOG DOWN and DOWN. The maximum travel up or down is to be limited by limit switches (simulated by stop buttons). When the UP button is pressed, the hoist lifts the load up until the STOP button is pressed or the UP limit is reached. When the JOG UP button is pressed, the hoist lifts the load until the operator releases the button or the UP limit is reached. The DOWN buttons provide the same functions, but the hoist lowers the load.
