This project helps you control 8 relays using RS485 link with the help of a PC. This kit can effectively convert a standard PC to a powerful PLC ( programmable logic controller ). At the PC end , you will need to use our RS232 to RS485 Interface or any other suitable RS232 to RS485...

8 Tactile Switch Input Board is a simple PCB offering easy connection of a standard 10-pin Box Header connector to 8 small type Tactile Switch with a jumper selectable pull-up / pull down of resistor network connected in parallel. Easy interface with PIC and Atmel Development board...

Description This circuit is used to design an inductive proximity switch. The resonant circuit of the LC oscillator is implemented with an open half-pot ferrite and capacitance in parallel (pin LC) and if a metallic target is moved close to the open side of half pot ferrite, energy...

7 Seven segment multi-plexed display is tiny board that has been designed around Common Anode 4 digit Display, Display has 12 Pins. The board is provided with current limiting resistors on all LED segments and 4 PNP Transistors to drive 4 digits, the project is ideal for easy...

This project describes a DIY wireless temperature and humidity monitor for kids’ or infant’s room using the Arduino platform, and inexpensive and easily available ASK transmitter/receiver modules. On the transmitting end, an Arduino nano senses the ambient room temperature and...

This single supply microphone pre-amplifier amplifies the output signal of an electret capsule microphone to audio line levels. An op-amp is used as a trans-impedance amplifier to convert the output current from the microphone into a signal-level voltage. The circuit works with 9V so...

This is a general purpose relay board accepting 8 inputs to drive 8 relays providing control requirement in your project. This board can also be used as an add-on card for the various Development board that we provide. Features Robust Design using NPN transistor to drive each...
