Hi guys i am doing a project on traffic automisation. the concept i want to use is to give time delays for LEDs based on the traffic density. I am new to arduino.so pls help me with this.which arduino model should i buy??how many LEDs can i control individually with arduino based on input from an external sensor??
thanks Can the PWM pins be used for giving output??
Ok So how do i use the analog pins as digital outputs?
