Arduino at home, at work, in the car
Recently, more and more posts are devoted to crafts based on Arduino boards. I also want to talk about several projects created on the basis of these boards. I am not the author of these projects and I have an indirect relation to them. But the real authors gave me the go-ahead to use their development in this publication. The fact is that they have no relation to IT and, accordingly, do not have accounts on Habré and his son Geektimes.
I give a literal description of the projects from the authors.
The project is designed to begin to solve the problems of finding switches, forgetting the disconnection and the need for squinting. The first part realizes the smooth switching on of the working surface lighting in the kitchen and the lighting inside the cabinet, for example, you usually have to dive under the sink with a flashlight. Illumination of the working surface of the kitchen is realized by placing the LED strip on the bottom of the upper cabinets. Short button presses simply turn the lights on and off. A long press switches on the mode of changing the level of light, gradual deadening, when it reaches zero, turns on brightly again. When the button is released - the light level is remembered and further short presses on the button turn on the light to the memorized level. Inside the cabinet, the light smoothly turns on and off when the reed switch is built into the wall of the cabinet. Further development involves the connection of presence and illumination sensors, an increase in the number of control channels, the implementation of decorative lighting for glass shelves and doors.
The program was tested on Arduino UNO with an AFMega8A-PU controller, and implemented on the Arduino PRO Mini.

Wrote a welding controller program for welding fittings. Run from the foot pedal in the presence of reinforcement rods.
Adjustment of three technological parameters:
“CLICK time”, “WELD TIME”
"TIME OF FORGING"
Additionally, there is a switch "AUTOMATIC MANUAL"

Light control unit on the car.
When you turn on the mode of automatic (dimensions, running lights, dipped beam) are turned on and off automatically. As the signal from the tachometer is on, the auto mode and the dimensions and the diode (automatic on) come on. After the signal disappears (after 10 seconds), the auto mode is turned off, and the dimensions go out after the ignition is turned off. When a signal appears from the speed sensor, the running lights or dipped headlights (depending on the illumination). When it disappears (after 2 minutes) they turn off.
When the unit is turned on, the integrity of the dipped-beam lamps is monitored, the voltage on board (min, normal, max) is accompanied by a light and sound alarm (the audio signal can be turned off by pressing a button). If you turn the turn signals (to A7), they will be accompanied by a beep. The project is assembled on Arduino Nano. It has been working for a month now.

Immediately make a reservation. Surely many will have a question about the readability of sketches for the Arduino IDE. Sketches are created automatically by the program using a graphical programming environment. As I said, the authors of the projects have no relation to IT and programming. These are intelligent and economic people with straight arms and a clear understanding of what they need.
Now there are several other projects in development that I know about. This includes greenhouse watering control, garage door control, combination lock and many other projects. If readers are interested, I will ask the authors to tell about their projects after their completion.

Light control unit on the car.
When you turn on the mode of automatic (dimensions, running lights, dipped beam) are turned on and off automatically. As the signal from the tachometer is on, the auto mode and the dimensions and the diode (automatic on) come on. After the signal disappears (after 10 seconds), the auto mode is turned off, and the dimensions go out after the ignition is turned off. When a signal appears from the speed sensor, the running lights or dipped headlights (depending on the illumination). When it disappears (after 2 minutes) they turn off.
When the unit is turned on, the integrity of the dipped-beam lamps is monitored, the voltage on board (min, normal, max) is accompanied by a light and sound alarm (the audio signal can be turned off by pressing a button). If you turn the turn signals (to A7), they will be accompanied by a beep. The project is assembled on Arduino Nano. It has been working for a month now.

Surely many will have a question about the readability of sketches for the Arduino IDE. Sketches are created automatically by the program using a graphical programming environment. As I said, the authors of the projects have no relation to IT and programming. These are intelligent and economic people with straight arms and a clear understanding of what they need.
Now there are several other projects in development that I know about. This includes greenhouse watering control, garage door control, combination lock and many other projects. If readers are interested, I will ask the authors to tell about their projects after their completion.
