I am a beginner for using the Arduino uno board and I need some help. A lot of my work at home are building models for a hobby. I saw the Arduino on the internet and saw that you can program it to make LEDs flash. I just need to know how many LEDs can I run on the chip.
also can i program the chip and take it out of the Arduino add it to a PCB.
328 and TLC5940 might look like this on a PCB. The silver cans in the middle are crystal oscillators.
