For the live demonstration you will receive a small PCB and a few components and will be required to solder the components to the circuit board. The circuit kit contains a 555 timer IC, 3 resistors, a capacitor, and LED, and a 9V battery connector. When completed, the system will slowly blink the LED. The schematic of the circuit is shown below. | For the live demonstration you will receive a small PCB and a few components and will be required to solder the components to the circuit board.
