My instructor ask me to build a water heater for our school project. The circuit should trigger up to 5 heaters depending on the preset temperature. The idea goes like this....
The first heater will turn on.... if the temperature doesn't reach the required temperature, the second heater will turn on also so that there will be 2 heaters turned on. But if the required temperature was reached by the first heater, the remaining heaters will not turn on.
I've already constructed the AC part of the circuit which will turn the heater on.... my problem is the circuit that will trigger it.
I was told to use a counter, a shift register, a 555 timer, and a thermistor.
Can anyone help me please????
