1 Channel Relay Module For Arduino In Pakistan

This AT-09 HM10 / HM-10 4.0 BLE Bluetooth Serial CC2540 CC2541 Module For IOS 6/Android 4.3 contains a BLE chip (a CC2540/CC2541). This AT-09 HM-10 Bluetooth Module allows performing serial communication with the BLE chip thanks to an Rx and a Tx pin. This 4.0 Bluetooth Serial Module is also very similar to the HM-10 module and is also compatible with it. So if you have some experience with the latter, you will get started quickly with the AT-09.

This board has a PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. There are many examples on the internet for using this board with Arduino. Do a search for “Arduino LCD PCF8574“. The I2C address is 0x3F by default, but this can be changed via 3 solder jumpers provided on the board. This allows up to 3 LCD displays to be controlled via a single I2C bus (giving each one it’s own address).

Mounting Bracket Holder Stand is specifically designed for the HC-SR04 Ultrasonic Sensor Module. With this ultrasonic sensor you can attach the le to your application such as small robots or DIY projects very quickly and conveniently. This best mount bracket is made from good quality Acrylic. This mounting holder has mounting holes of a diameter of 3.8mm. Use this Arduino distance measuring sensor to easily attach your ultrasonic distance sensor to your robots, onto a servo for panning, and anywhere else you’d like. 90 degree mounting with 3 screw holes at the base and 4 screw holes for the ultrasonic sensor itself.
