Blinking LED is the first step you would like to take to get started with electronics. In this tutorial we are going to connect an LED with ATmega32, which is an AVR series microcontroller. We are going to blink the LED at half a second rate. Components Required Hardware: ATmega32A Microcontroller Power supply (5v) AVR-ISP Programmer 100uF Capacitor …
This LED candle is built to mimic the look of a traditional candle without the dangers associated with an open flame. It uses high brightness LED and is controlled by ATtiny85. It could be useful as movie props where you cannot afford to have a candle go out during a take or in your home in places …
AVR Mask1 is a led mask built around 74hc595 shift register and 8×8 led matrix. The “Dylan Dog” comics decoupage, in conjunction with his stands, make it good looking. t has 4 8×8 led matrix, 2 for the mouth, and 2 for eyes. When the user get closer to the mask, the IR sensor placed on the back activate …
This device can be used to remotely control the speed of an AC fan and to switch it on or off. The remote control is a cheap NEC Format remote, usually supplied with small DVD players. Three buttons are used to command the circuit. The UP key increase the fan’s speed while the DOWN key decrease …

In the Atmega 32u4 Based USB Controlled LED Series Project, it was demonstrated how to use control transfer to receive data from computer to the peripheral. In this project, it will be demonstrated to transfer data from microcontroller to the host computer. For this, the device will be configured as HID Class Device again. An HID …
Timers are widely used in industrial and domestic application for automating tasks. Microcontrollers can be used to design versatile and accurate timers with ease. Here I present a simple timer that can be used to turn on/off a load after user specified time. The Timer uses a standard 16×2 lcd module for user interface (UI). User can set the …
LM35 series is a low cost and precision Integrated Circuit Temperature Sensor whose output voltage is proportional to Centigrade temperature scale. Thus LM35 has an advantage over other temperature sensors calibrated in Kelvin as the users don’t require subtraction of large constant voltage to obtain the required Centigrade temperature. It doesn’t requires any external calibration. …
