Skema Rangkaian Jam Digital

The figure on the right is displaying the condition to be displaying 10:32:54 p.m. switching every 500 milliseconds. In the switching time of the actual circuit, it is 1 millisecond. So, all digit sees to be displayed at the same time. The light of the LED is 1/6 compared with the continuation [...]

Digital LCD Thermometer Circuit
At this thermometer, the IC thermo sensor (S8100) or the diode (1S1588) is acclimated as the thermo sensor. Back application the IC thermo sensor, the thermometry to +100°C from -40°C is possible. Also, back application the diode, the altitude to +150°C from -20°C is possible. Both sensors are independent in the kit.
