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 [...]

At command for communications with SMS-CENTER.At hand phone GSM there is facility to data access applies serial connection, for data access is required by instruction sequence at interface hand phone. ETSI (European Telecommunication Standard Institute) that is the instruction standard in technical specification GSM. instruction phone is started with character AT and terminated with enter [...]
The 555 Stepper Motor Pulse Generator kit will support you together with the pulse needed to drive your favorite DC Servo Motor application. This kit uses the well-known 555 timer IC for creating the Stepping Pulse. Quick Overview # Input : 5 to 12 VDC @ 25 mA # TTL/CMOS interfaceable # Jumper selectable two [...]
Temperature Monitor with IC LM741 or LM301 Using a thermistor in the position shown makes a heat activated sensor. A change in temperature will alter the output of the opamp and energize the relay and light the LED. Swapping the position of the thermistor and 47k resistor makes a cold or frost alarm. Temperature Monitor [...]
The wires from the Logic PCB connector to the stepper motor in a TM100 Disk Drive are as follows This means that, to use the stepping sequences as is, the Green and Brown wires are the wrong way round. There is no need to alter the wires at the connector, of course – it can [...]
