Arduino Options

This is a PCB KIT designed to be used as a finished product for your Bluetooth applications. It can also be used as a Bluetooth development board for the Arduino UNO. This PCB has a pre-programmed Atmega328p designed to accept an Android Bluetooth App to control a relay. This means, that from your cell-phone, you can control (turn on or off) a single device.

It can be used in automotive applications where you want to turn something on or off with your cell-phone.

It contains an Atmega328p on a socket, a 2-position DIP switch for additional software options, a SPDT Relay rated for 7Amps, and an LED indicator.

It also has room for an HC05 Bluetooth module which is wired to D2 & D3 which frees up RX0 & TX0. Use the Software.Serial library to control it. This frees up RX0 & TX0 so you can develop your program even better.

It has an on-board 5v Voltage Regulator. The input voltage can be anywhere from 7.5vdc to 15vdc. If you need a higher input voltage, change the three Aluminum Caps for a higher voltage rating.

There are four mounting holes. The PCB is 2.75" x 2.20", FR-4 expoxy glass, 0.062" which is double-sided, Plated Thru-Holes. STAND OFFS NOT INCLUDED. 

It was deigned to work with an Android App to control the Atmega328p. It is offered as a kit, or as a fully Built & Tested unit.

InstructionsIn this Video I am using a free app from, You can find the app on the Google Play Store listed as Arduino Bluetooth. Turn on the Bluetooth settings on your mobile device.Next turn on the Bluetooth app that you are using. Then select available Bluetooth device " HC05 " ... The password will eirther be ( 0000 or 1234 ). Select "LED control " for easy access. . .You will now have control over your kits relay functions including on board LED indicator.
