hi.. please help me with any simple project using 7404, what is 7404? is it a triple voltage regulator? or an inverter? please help me how to use 7404..
is there any simple / traditional methods to rewind the transformer? without using any machine..
if i want to build a linear power supply with voltage showed on the LCD, which one is better? i use an ADC or a DAC? if i use DAC, i can set the output voltage within push button connected to int 0 and int 1 of 89S52, and output from 89S52 will be converted into analog voltage by DAC, and if i use ADC, i can set the voltage with a potentiometer, and then convert it into digital signal, and send into 89S52, which one is better for learning? is there any tutorials on how to interfacing the LCD using 89S52?
thank you
