Arduino 4 Channel Relay Module Board In Pakistan

2 Channel Relay Module Relay Board Arduino Relay Module With Optocoupler allows a wide range of microcontrollers such as Arduino, AVR, PIC, ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs. 4–channel relay interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliance

HC-06 / HC 06 / HC06 Bluetooth Module Serial port bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it simply for a serial port replacement to establish a connection between MCU and GPS, PC to your embedded project and etc.

The Digital Light Dependent Resistor LDR Sensor Module is used to detect the presence of light / measuring the intensity of light. The output of the LDR module goes high in the presence of light and it becomes low in the absence of light. You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is the digital output, so you will know is the light present and decide what to do with it.LDR photoresistor sensor module comes with an M3 mounting hole for ease of attaching it to an object. Onboard, it provides an LDR, high sensitivity and commonly being used for light detection.
