Matrix Formation

l4.jpg

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.
