Road accidents became a matter of concern due to the huge increase in traffic. The primary cause of accidents is due to the drowsiness of drivers in the nighttime. Fatigue and drowsiness are some of the leading causes of major accidents on Highways. The only solution to this problem is detecting the drowsiness and alerting the driver. So, in this project, we have thought of building a Driver Drowsiness Detection and Alerting System for Drivers using Arduino Nano, Eye blink Sensor, and RF Transceiver module. The basic purpose of this system is to track the driver’s eye movements using Eye blink Sensor and if the driver is feeling drowsy, then the system will trigger a warning message using a loud buzzer alert.

How much passion do you have for music? If a lot of then definitely you have a speaker or Bluetooth speaker. You want to be cool in front of your friends when you are showing your speaker to them. So, for the DIY speaker, we have an amazing Arduino based Bluetooth Speaker. Bluetooth speaker has now become a pretty popular household gadget that we use on a daily basis. So, for today's article, we thought to design and build our own Bluetooth Speaker. To make things a little more interesting, we have added a strip of WS2812B Neo Pixel RGB LEDs that will be used to visualize the music. In order to make the visualization more responsive, we have used colorchord - sound to light conversion tool that is developed by one of my favourite youtubers cnlohr.

We know that Arduino has ADC (Analog-to-Digital Converter) feature but what if we want Digital-to-Analog Conversion with Arduino. We have the hack for this. We will connect an MCP4725 DAC IC with Arduino Uno and provide analog input value to Arduino pin A0 by using a potentiometer. Then ADC will be used to convert the analog value into digital form. After that those digital values are sent to MCP4725 via the I2C bus to be converted into analog signals using the DAC MCP4725 IC. Arduino pin A1 is used to check the analog output of MCP4725 from the pin OUT and finally display both ADC & DAC values and voltages in the 16x2 LCD display . For this, you need circuit diagram and Arduino code; You can check out this Arduino ADC Tutorial , here you can find circuit, code, and a step-by-step guide for Digital-to-Analog Conversion with Arduino.
