Arduino in the car. Instrument dubbing

1. Speaks in voice (5 volume levels) about various events (events are described below)

a) male
b) female

Voices are synthesized on a computer, recorded as a set of mp3 files on a micro SD card. This means that you can change or record them.

2. Settings are performed with the remote control from the TV (or any other with a sufficient number of buttons, I highly recommend the remote control with the buttons 0-9). Settings are remembered at the moment of change.

3. In case of failure / loss of the remote control, the detector can be quickly switched to the “no sound” or “no sound except handbrake” modes. For this, a triple switching on of dimensions is used (the idea of ​​using the flashing dimensions as a control signal for adjusting the tap from some kind of DRL brightness adjustment device).

- Handbrake (if the parking brake light is on while driving)
- The high beam is on (the far flash is ignored, warns once after switching on, does not remind further, until the far one switches)
- Turn on the running lights (if the movement is started without the dimensions included, my DRL and the near one do not work for me if the dimensions are not included).
- Voltage on-board network (accuracy up to a tenth of a volt)
- Exceeding the speed threshold of 40, 50, ... 120, 130 km / h.
- Lowering the speed threshold of 40, 50, ... 120, 130 km / h.
- Changing the volume, switching the voice, turning off / on each of the events being voiced (switching on the voltmeter simultaneously causes voltage to sound).

Video with demonstration:

1. To the speedometer - just three wires: ground, +12 (from here we take power to the device and data for a voltmeter), a signal from the speed sensor.

2. For light bulbs - parking brake, high beam, instrument lighting (dimensions).

The matching of the levels is made quite simple - the arduine outputs are pulled up by the internal resistor at “1”, and the 12V level signals from the dashboard go through the diodes. When the panel goes +12, the diode is closed - on the Arduine "log.1". When the signal from the panel goes to ground - the diode is open, the internal pull-up resistor is ignored, at the Arduino output "log.0".

A voltmeter is simply a resistive divider to an analog input. The ratio is approximately 1:13, from the calculation that at the maximum on-board network voltage of 16V (emergency mode), the ADC will reach its limit with a reference signal of 1.2V.

1. Arduino nano v3


2. MP3 Module - DFplayer mini


This module in the Internet diagrams is connected via tx / rx signals, I added the analysis of the busy signal, in order to catch the moment of the end of the sound playback, so that the new notification would not interrupt the current one, but stand in a queue.

3. Amplifier PAM8403 (optional)


4. Development board, 5 resistors (2 per ADC voltmeter, and 3 per DFplayer pins), 4 diodes (matching with + 12V), as well as a pair of capacitors and a +7 V power supply stabilizer chip (LMSR805) 7805, because it was in stock and does not heat up), piezummer (squeaks when mp3 files queue overflows, more for debugging errors), connectors for connecting an IR sensor (jack 2.5 in my case, but this is unprincipled) and dynamics ( I took RCA), well, and the connector for the instrument panel (I took the IDC10, with snaps on the dad - quite light and multi-contact)

From the firmware text, you can easily see where all of the analyzed signals are located, where to put the codes of your IR remote control (you can take them using the IRRecvDump demo sketch). Also, the constants clearly spell out the response times of voice speeds (note that the speeds are sounded a little earlier than they are actually achieved - in order to have time to slow down without exceeding).

For debugging, debugging and demonstration, another arduin was used - the arduino uno and the LCD display module and buttons.

She knows how to give signals - dimensions, high beam, handbrake, and change the speed from 0 to about 150. Among the shortcomings, there is no suppression of contact bounce, but this moment does not really bother me.
