Hello good day to everyone,
I have been working in a proyect where I need an accelerometer (ADXL312 of analog devices) to communicate with an ATmega8 thru SPI.
So the configuration of the ATmega8 I believe is correct, I haven't seen any assembler posts n.n but I am working with it, so i will...
thats the thing, i'm not sure if connecting a filter right next to the photodiode is correct... i mean, the photodiode varies its voltage in function of the IR light recieved, if I filter that voltage signal in theory i was supposed to get something because it had the emitter right next to it...
Alright.
Since the robot I am building is very limited on space for circuit that is good news.
I will post the results when i test it if you like, with and without the capacitor.
Hello everyone, good day
A little part of a proyect needs an obstacle sensor, so i have an IR emitter and a Photodiode IR reciever
The thing is I want to filter the sunlight and noise. But I have a very limited physical space so I cant use 555 or opamps...
So the only think that came up to my...
Hello everyone, good day;
I am developing a proyect where a little part of it is to sense the intensity of the daylight. I am using of course using LDRs.
The regular circuit would be a voltage division between a resistance and the LDR, next would be an opamp buffer to separate impedances...
