Hi, actually it is my first time doing my school project on electronic circuit. So, I am quite lost and stuck. My project needs to have light sensors to detect the sun and compare the value between two sensors so that the system will follow the track where the sensor senses more sun light.
I wanted to draw out a circuit for a photo diode, 4quadrant photodiode and a H bridge for my motor. I google for the circuit. Then pop out so many diffent type of circuit. So, i am so confuse. Can anyone show me a basic design of circuit for a simple photodiode sensor and a 4quadrant photodiode? I got a H bridge schmetic diagram with values for all the components. But are these values apply to any servo? If not, how should I re calculate?
sorry for asking troublesome question. But I am really really stuck and lost. Thanks for any help and advise.
