Atmel AVR circuits, Atmel AVR projects have been realized with microcontrollers of Atmel brand, amateur, professional applications, most of which are source codes.

Effect Led Stars PCB

ATtiny13 Led Stars There are source PCB drawings, Source and hex code files, Proteus simulation files. Added transistors to increase the number of LEDs. There are three printing options in the files. According to the scheme: instead of LEDs through a 1kOhm resistor to the base of the NPN BC547 transistor, then the LEDs are

RGB Strip Led Vu Meter PWM DFT

In Vu meter circuits, the LEDs give light according to the level of the sound signal. In this circuit, the LEDs give light according to certain frequencies (various calculations and PWM control). Led colorful music circuit, dance lights or disco lights project made with ATtiny13 microcontroller. It allows the LEDs to light up according to

Peak Hold Led Bar Vu Meter Circuit

The vu meter circuit, which can operate peak hold and normally, has a 2×20 LED peak indicator. Leds are controlled by Atmega8 microcontroller. The display range is -34 to +4 dB. The LEDs are controlled by multiplexing 4 LEDs in 10 steps, the multiplex frequency is about 100Hz. R1 … R4, their resistor (270-ohm) limits

Musical Ring Box Led Heart Circuit RGB Effect

I shared the ATmega88 microcontroller Led Heart circuit years ago. The LED Heart circuit that I have applied is controlled by the ATmega8 microcontroller. I made a lot of decoration on the PCB top floor and the PCB was made more useful for additional circuits. In the LED heart circuit, 22 ports of ATmega8 (ATmega8A-AU

Voltage, Current, Temperature, Power and Load Resistance Measurement

In addition to measuring voltage, current, power and temperature, the meter can also calculate the resistance of an attached load. However, this is not the most important difference – more importantly, this meter can also measure negative voltage and current. Recommendations: the meter can be used in a laboratory power supply or other power system.

DMX Servo Driver Circuit

The ATmega168 project is a continuation of devices with DMX interface designed for set designers, people involved in the setting of events, musicians, etc. Our controller is able to control four servos, with which you can, for example, control lighting or animated elements of the scenery. After the transmission decay, the servos may be in

Lighting switch in the garage

Driving a car into the garage after dark can be fatal if it has no lighting. The presented system automatically switches on the lighting, without leaving the vehicle. He will also remember to turn them off later. The switch system is designed for 230V AC supply. It works by detecting a beam of light (coming

ATmega88 RGB lamp with DMX interface

The design of a light source with a DMX interface, consisting of RGB LEDs panel, and thus able to illuminate objects with light of almost any color. Over 60 super-bright LEDs with up to 100,000 mcd luminosity were used in its construction. The device fits the KM-95 enclosure, which has a handle for mounting it

ATmega128 DMX Scanner

DMX interface. These were mainly receivers and transmitters, as well as devices enabling the development of DMX networks. When running prototypes or large installations, you will definitely need a DMX scanner that can provide invaluable services. Recommendations: the scanner will be useful to people dealing with technical equipment on stage, technical setting of events, etc.

TB6560AHQ ATMEGA64 CNC Projects

The subject of this project is realization of CNC milling machine, designed for production of smaller machines light alloy and PCB components. This will be subject to selection of mechanical components and drive. The mechanical construction should not be too complex due to limited production means, however, a laser cutter is available and the possibility

ATMEGA16 Led Cube Circuit

The Led Cube project was made of LED cube, one side consisted of eight LEDs, a total of 8 obsahuje = 512 LEDs. By multiplexing always the eight LEDs, any spatial “picture” can be made from luminous LEDs. The cube can be used for aesthetic purposes, presentations, games (eg 3D Snake), etc. A total of

ATmega64 RGB LED Cube Circuit

RGB Led cube circuit is basically a real 3D display. Its resolution is determined by the number of LEDs. Greater resolution offers more faithful effects, but the demands on RGB LEDs and controls increase with the cube. So it is advisable to choose the right compromise, between difficulty and resolution. Here is the size of
