Introduction Let us introduce the Breath-o-Matic alcohol sensor. The Breath-o-Matic is an electronic, non-invasive method of measuring a human’s blood alcohol content (BAC). Its elegant, yet discombobulated design embodies a cheerful mix of mechanical and semiconductural components. Simply blowing into the mouthpiece causes the Breath-o-Matic to automatically begin taking a sample of your own foul …
Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm to 400 nm. The ML8511 is an ultraviolet sensor that output an analog signal correlated to the amount of UV light detected. By datasheet the sensor detects wavelength from 280nm to 560nm. Here I’ve implemented a driver for AVR Atmega, portable to other microcontrollers, that correlates the sensor output …

Sometimes when tuning various electronic hardware we need simple signal generator with various waveform and frequency. One of the options is to by a professional with variable gain professional coating and many additional functions. But if you are an amateur you might want to build one. This small project is dedicated for building one of …
This article is in continuation of PWM generation using AVR timer. In the previous article, PWM generation using Phase correct PWM mode is described. However, there are some applications like DAC, power regulation and rectification etc. which require high frequency PWM wave. The PWM generation using Fast PWM mode is suitable for such applications. This article focuses on Fast …
Have you ever made your own robot? Here is a very simple and easy robot. In this project, I will explain how to design and build a Line Follower Robot using microcontroller. The Line Follower Robot is a basic robot that follows a specific path indicated by a line (usually a black line on a …

This simple DC motor controller allows for one direction motor control and has been built entirely of reclaimed electrical parts. Using MOSFET’s for motor control instead of control chips, allows for an external power supply and electric isolation of the motor and control board. Which allows for the use of higher voltage and amperage motors …
