circuit this way. It appeared that the 110 ohm resistor was in series with the parallel combination of the 330nF capacitor and the 1Mohm resistor. That was a little confusing because I had assumed that the capacitor would be in series after the bridge rectifier as in a capacitor-input filter. After a few attempts to sketch the rest of the diagram‚ we decided to use Multisim. Multisim was a very useful tool. It allowed us to use all of the components on the circuit‚ and‚ through trial and error‚ create a

The program is burned into ROM of microcontroller written in either Embedded C or assembly language. The power supply consists of a step down transformer 230/12V‚ which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.
