You can use this circuit to give auto trigger for your secondary flash light. You don’t have to worry about wiring for the control, because using this circuit your secondary flash will be automati8cally triggered when it receive the light signal from the primary flash. Look at the circuit’s schematic diagram below. The [...]

Introduction Interfacing humidity sensor can be difficult because of the sensor’s drive requirement and their wide dynamic range.  We can customize the circuit to obtain reasonable accuracy within the chosen range by carefully selecting the devices that comprise the analog front end. Here  we present a case study to design analog signal conditioner for [...]

Many new computers now only has USB port, and this serial to USB adapter might be the only help for old devices that provides only RS232/COM Port. This serial adapter uses FT232 USB-RS232  converter IC from FTDI (Future Technology Devices International).  The main features of this USB serial adapter chip are: 384 [...]
