Week -2
1.Solenoid door bell
Ther doorbell use a electromagnet called solenoid.the square pulse generated with time delay 2seec and passed to switch.when the threshold value is less than physical value the circuit closed and curren passed

2.temperature controller
Using repeatin sequen stair pulse is generated .the three temperatures are given as controlled input to thermistor using repeated sequence stair.the temperature value given as array data input[292 300 300 296 296]
The sample time taken as 10sec& runtime 50sec the switch On when Output of voltage sensor is greater than 1 otherwise OFF
