Latest design of night light saver circuit built with AT89C2051. Nice firmware using c coding developed with SDCC....Go

This is my long history the device that controls my home's night light, air-conditioner,etc. The device is a Miniature Real-time Controller. The circuit uses only three chips, a 89C2051, DS275(or MAX232), and 74LS07 open collector driver. The scheduler for time on/off of 6-channel output can be made by downloading from PC and saved into onchip RAM. Each output provides a 20mA sinking suitable for driving a homemade opto-triac or big solid-state relay for heavy load....Go

Wagner Lipenharski has a very helpful microcontroller page. His page is packed with lots of code examples and interesting ideas for the AVR as well as 8051. A good resource for the beginner or expert!besides,this site provide some cool stuff about IR ,such as SONY IR Remote , HITACHI IR Remote,NEC IR Remote,PIONEER IR Remote ,JVCRemote IR Remote ...Go

The Frequency is passing through an op-amp to convert it in a square wave. The ouput of the op-amp is feeding the 3*8 bits counter (24 bits) who can accumulate at a maximum of 16777216 count. The maximum frequency you can measure without changing the time base of one second is 16.777216 Mhz. The ATMega8 have 3 functions: enable the counter gate at each second, read his value and display it on the LCD....Go

Build your own a personal data logger for recording analog signal. The MiniLOGGER provides 8-channel analog input(-99mV to +999mV), 1-channel pulse input, battery backup 256kB SRAM, Real-time Clock, and RS232C. Start/Stop recording can be made by MANUAL switch or preprogrammed Start/Stop Time. The format of uploading data is ASCII format, suitable for importing and graphing by Excel or any Scientific Plot Program. Exemplary circuit used for measuring Insolation and Air Temperature vs. Time is included....Go
