I have an android app that connects to an arduino and turns on/off a led when battery reaches min/max percentages set by user. The app right now turns bluetooth on turns led on/off and then disables bt, and I now want to remove the option to disable bt, so that I can use bt with any other device at the same time. I also need to remove the disable button

arduino coding to be done for controlling 3 motors, 1 servo with an input from Potentiometers 1,2 3 and 4 and data coming from bluetooth Rx Tx according to a specific logic, complete logic and flow has been worked out. Coding for it has to be done according the the requirement.
Hi jartur, I noticed your...details over chat. I am creating a new product. A a simple 4-digits clock, but instead of regular time display it will shows it a bit different. I created a prototype on Arduino. I am looking for the electronic design of this device. I would like to make it as cheap as possible. further details via chat...its the best
Instructions for the Espresso Machine: * Diagram is needed to make connections. -Arduino UNO -Relay -I2C LCD display 20x4 -LED lights -Keypad 4x4 or two 1x5 (prefferably) -Buzzer (beep) -Gicar 1/4" Standard Flowmeter -Temp/Humidity sensor (DHT11) just to show information on display. When unit power up: -Display show boot screen
I need to create a prototype on Arduino Mega for filtering traffic coming from Serial0 and Serial1 to Serial2. Serial0 has a string of integers mixed with lot's of noice. This have to be converted to pure integer string and then converted to HEX and transmitted to Serial2. Serial1 have to be just repeated to Serial2.
I have a widget that connects to an arduino nano, throgh an hm-10 BLE module. The App turns a led on in the arduino, and I need to turn it off when max battery percentage is reached and either shutdown is enabled or disabled. Right now the led only turns off when shutdown is enabled. I also need to set a thunderbolt image on top of the battery image

I'm looking for you to write some articles of Arduino and Raspberry Pi projects. It can be interesting or enlightening, simple or difficult. Or if you have other ideas in electronics, that would work too. You should have some original thoughts, tested it out and write down your project in details. Some illustrative pictures and videos are needed. We'll
