SINGLE PHASE PREVENTER SYSTEM

FEATURES:
Switches of three phase supply when any Phase voltage dips below 200v
Switches of three phase supply when any Phase voltage rises above 280v
Switches system back on when voltages normalize
LCD to display STATE of system
Note*
Variable resistors in series with AC phases are to help simulate under and over voltages

AUTOMATIC BOOM GATE FOR TRAIN/ROAD INTERSECTION

FEATURES:
Shuts gate, turns traffic light red, sounds buzzer at start
Has four sensors all tied to the same 555timer
Uses PWM from Microcontroller for IR emitter
Has upper and lower limit switches to prevent gate from over shooting(these have to be activated manually during simulation)
Verifies to ensure that intruption is actually caused by a train(shortest train at highest speed determines shortest time that a train could possibly interrupt the sensor. Set to 5 seconds)
On detecting a train, Red traffic light comes on, buzzer sounds, gate closes
Note*
Red LED used in place of IR emitter(not available in ISIS)
Push button switch used in place of IR detector(not available in ISIS will have to be activated during simulation)

DATA LOGGER

FEATURES:
Measures Voltage and Current values and logs them to EEPROM(bad idea)
Logs time and date together with measured values
 SETUP:
 At startup press INC key to set date, DEC key to set time
 In Date setup mode, press INC key to set year, DEC key to set month, AUX key to set day
 In Time Setup mode, press INC key to set hour, DEC key to set minute, AUX key to set second
 Use INC, DEC keys to increase or decrease values
Note*
Time may not be so accurate
