IC 4017 × 3
Matrix Formation
LEDs should be connected in the form of a matrix
the positive terminal should go the row
and the negative terminal should go in the column.
Temperature Sensor and ADC
for calculating the temperature temperature sensor should be utilized and calculating its analog value analog to digital convertor is used. i am using ADC0809 for the circuit. if you have in built ADC in controller you can discard ADC and connect sensor output directly to microcontroller.
Circuit Diagram
RTC for Time Clock Output
DS1307 ic can be used for calculating the actual time for the circuit.
