These are high-voltage, high-current Darlington transistor arrays. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching (more…)
An Excellent way to expand your A/D convertors I/O capability. Multiple Analog Inputs can be routed to a single Opamp or Analog Input of (more…)
These devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages.
FPGAs are powerful programmable logic integrated circuits. FPGAs are wonderful devices to design digital logic with. You can design a circuit on your computer and have it running on your desk in minutes.

- Optical switch with photo sensors
- Mains Current Indicator with a LED
- Microcontroller Interfacing
Can you help me to find circuits which uses photo-sensors.and if you do have them, would you please send them to me.
This is a mains 230V AC load current indicator and is a LIVE CIRCUIT, so take care. The Resistors have to be a fusible ceramic wire wound.
None of this is specific to a particular microcontroller or family of microcontrollers; it applies equally well to PICs or AVRs or 8051s or any other processor.

Basic Electricity – Start here if you don’t know anything about electricity or electronics. These pages cover the basics. They are great for young students.
QRZ was founded in 1992 by Fred Lloyd, AA7BQ as a spinoff of what was once called the “Callsign Project”, a cooperative effort designed to obtain and distribute FCC database tapes.
