ir transmitter receiver circuit diagram
Hi
I think you can make the circuit using typical TV remote controller ( sony or toshiba) and use AVR u to receive the data so you can get many channels and it will be cheaper
and to program the micro use BASIC or C which support IR data transformation
interfacing thermistor
Hi
we can use an operational amplifier to make the sensor response greater
such as LM324 or LM741 by amplification factor of about ( 8 ) or ( 10 )
adc interface into micro without ref
hi
to interface the LM35 into the micro you need to use analog to digital converter
ADC which converts the voltage produced by LM35 into digital value that you can read by the micro controller
note that LM35 gives (10 mV) change for (1 °C ) change and it...
Hello Alek66..
I can tell you how to control your Palm with PS/2
you can connect the Keyboard (PS/2) to the micro controller (AVR)
and very simply you can get the charecters from the Keyboard and resend it
to your palm using RS232 then you can program it to receive these chars...
Hello 001
I think that you are designing your own project .. so you have to design
1 - the the sensors scanner
2 - convert the analog values into digital
3 - send the data you got and the address of the sensor serially
(UARTmode)
4 - modulate the data using FSK modulation (such as in...
