This circuit is a digital logic system that uses a DIP switch to provide input to a network of flip-flops and logic gates, which process the input signals. The output of this processing is likely indicated by LEDs, which are connected through resistors to limit current. The circuit functions autonomously without a microcontroller, relying on the inherent properties of the digital components to perform its logic operations.
This circuit utilizes a CD4011 Quad Input NAND Gate IC to process inputs from two DIP switches, allowing for multiple configurations based on the switch positions. The output from the NAND gate controls several red LEDs, which are connected through resistors to limit current, providing visual feedback based on the switch settings. A 5V DC power supply powers the entire circuit.
This is a digital logic circuit that uses a DIP switch to provide input to a series of logic gates (AND, NOT, OR). The outputs of these gates are indicated by LEDs, with resistors serving as current limiters for the LEDs.
This circuit uses a WeMos D1 R2 microcontroller to control a 5V 2-relay module, which in turn controls the power to an AC bulb and a cellphone charger.
