Project 1 – LED Blinking: LED Chaser

In project 1, you are about to experience how to program a LED chaser which can be increase the running speed by just a single button pushing. While releasing it, the running speed will slowly back to normal. In here, we are going to use total of 6 LEDs and will connected with a current limiting resistor before plug into the I/O port.

  1. Thanks for your feedback! You’ve got sharp eyes 😉 The diagram has error in it. We’ll fix that asap.

    Actually both ways work. However since the diagram may confuse you, please follow the statement instead. Thank you!

  2. Hi, newbie here. I might be wrong, but, the wire connections shown in LED connection picture seem different from what the text instruction says? Text says “…connect the anode (+ve) of all LEDs to 1K Resistor and end of resistor is connected to the VDD (Power Supply). On the other hand, the cathode(-ve) of all LEDs are directly connected to the PORTA.0 until PORTA.5,” but in picture the end of resistors are connected not to VDD but to PORTA.0 until PORTA.5 through orange, yellow, blue wires etc? I should follow the text and not the picture?
