Isolated RS422 Interface Circuit Figure 1 shows the circuit diagram of RS422 interface. Connector K1 is linked to the serial port of the PC, power to the PC side of the circuit is derived from the signal lines DTR and RTS. Positive supply is derived from RTS and negative supply from the DTR line. Optical [...]

Power Amplifier Circuit with 2n3055 Simple and low cost. The optimal accumulation voltage is about 50V, but this amp assignment from 30 to 60V. The acute ascribe voltage is about 0.8 – 1V. As you can see, in this architecture the apparatus accept a big tolerance, so you can body it about of the components, [...]
Dancing Leds Schematic Diagram Device purpose: The basic circuit illuminates up to ten LEDs in sequence, following the rhythm of music or speech picked-up by a small microphone. The expanded version can drive up to ten strips, formed by up to five LEDs each, at 9V supply. Circuit operation: IC1A amplifies about 100 times the [...]
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 [...]
Here’s a alarm clock circuit based on PIC Controlled. Two circuit boards put together a simple PIC based design comprising of two interlinked vero-board cards. The larger of the two circuit boards holds the 5V power regulator, the display processor (a PIC 16F74), the real time clock (Dallas DS1307), 3V backup battery and buzzer. See [...]
