This project describes the construction of a garage door control system based on ATmega16 microcontroller. The design uses a simple hardware to control a Garage Door with an RF Transmitter-Receiver Kit (AM110C1-315 and AMHIRK-315AR3 from OKW Electronics). With a single button press, user are able to open or close either the main gate or garage door, depending the use or application of the unit. The system also responds to a photocell when there is an object in the main door trajectory. Garage Controller Project Firmware, Schematic and Documentation circuitcellar.com

The project goal is to create 300W audio power amplifier for 4-ohm DIY speaker with low distortion based on IC LM3886. It's hope that the amplifier can produce deep, tight and punchy bass while keeping the excellent mids and highs from other gain clones.The schematic uses LM3886 in the inverted configuration, the reason is that user can use a trim pot to adjust the DC offset of each 3886. After some adjustment, The project able to get the DC offset of each 3886 to about 9mV, because this is a ...

This simple, secure and cheap home security system is activated and deactivated by little Rolling Code transmitter. The security system is equipped with two sounder, internal with piezo speaker and AG8 external sounder, a microprocessor controlled external sounder with a built in strobe and rich of features (silent installation,two flash settings, optional sounder settings (multi-sweep or two tone), selectable timer). To detect intruder, there are two sensors are used in the project : magnetic contact for the door and impactor, a smart shock sensors for the door.The project which ...

If you want to control your PC with your any remote but don't want use microcontroller the this project is for your. This PC Infrared Receiver project is very simple. It uses software to decode received code from IR instead of MCU and simple hardware to receive IR signal from your remote. The advantage using software than microcontroller based infrared receiver is when problem happen with code of IR-control then you only need upgrade the software, no need change the hardware.The project use Girder as software remote and Igor plugin. ...
