Design a long-life battery powered circuit, connected to the following external parts: an Arduino Pro Mini 5V 16MHz. a HC-06 bluetooth module. an A3144 hall effect sensor. a 3 pin switch. a DC motor, preferably running at 9V. a suggested 6 pcs 1.5 V Energizer Ultimate Lithium AA batteries. The Arduino will have a power down function. It can sleep-wakeup-sleep for weeks when it’s not paired over the bluetooth. The switch as well as the hall effect sensor can be in either of their states (“ON” or “OFF”) for weeks, during which time they shouldn’t drain the batteries. They should only use energy when the microcontroller is checking their status. The DC motor will only run for a few times a week during a few seconds. It should run on about 9V. I need your help to design a complete working circuit with components etc. (not modules) in Fritzing or similar, which I will solder on a prototype board after testing on breadboard. In the future, I want to change to a 3.3V Pro Mini and Bluetooth LE and hopefully get the device working for years without battery change.

hello Sir/ Ma'am I have 4-years experience in PCB layout design.(multilayer, flexible)(IN EAGLE) we can discuss over chat what type of PCB you exactly want, any size shape restriction, antenna design(if required ) from last 2 years I am working on Home Automation products(Arduino(atmega328) based) most products are custom designed. for example 1. RF remote(transmitter) which is a combination of Arduino, nrf24l01+, mpr121and IR. 2. RF power module(receiver) which is a combination of Arduino, nrf24l01+ and relays. 3. wearable electronics product which is a combination of Arduino, hc06(after replaced by ble (cc2541) and strain gauge. all these products are similar to your product. you can check my portfolio for samples. Skills CAM/CAD(AutoCAD, VECTARY) PCB design(Eagle) Embedded Coding Product development Amplification Touch interface( capacitive ) Power management Communication(I2C, SPI, UART, Bluetooth, WIFI, USB) DC-DC and AC-DC power supply Barebone boards Development boards Experience Hardware design engineer, Home Automation Startup Hardware design engineer, intern at Wearable Electronics Company Please check my portfolio.

I have over 35 years experience as an electronic design engineer, please see my profile for more details The current price and timescales are only place holders to allow me to communicate with you I would prefer to work in milestones but cannot define these until have more details Can you explain a bit more about the sleep mode. Do you want the Arduino to stay awake but have the ability to power down everything else. Alternatively do you want to put everything to sleep in which case how will it be woken up? If you think I can help then please send me further details Best Regards Dave Lelievre

Helllo. I have an experience in low-power Arduino-based devices and cam make it for you and help with assembling My current price is for a "normal" Bluetooth only, but I also wirk with BLE in my projects.

Hi, I have experience in Arduino developing. To reach best power saving result you need to use ATMega 328 and not Arduino Pro Mini. I can design circuit for you. Please specify in details working algorithm of your unit - - condition to ON/OFF of HC-06 bluetooth module - condition to scan A3144 hall effect sensor Your device must be powered by pulse switching voltage regulator to save energy. And will use less energy if is working on 3.3V / 8 MHz It is possible to decrease 3.3V and 8 MHz parameters also. How to manage 9V motor - to one direction or you want to rotate forward and reverse? Forward and reverse require motor driver bridge. HC-06 and A3144 power will be managed from Arduino. HC-06 require 3.6 - 6V - not possible for example to power with 2.5V. A3144 require 4.5 to 20V - not possible to 2.5 or 3.6V (Arduino pro mini 3.6V / 8 MHz) You need to meet different requirements for power and data signal level. Regards, Slavi.
