Getting Started with the HC-SR04 Ultrasonic sensor - Arduino Project …
Aug 5, 2017 · In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to the receiver. You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. Let's get right to it!
How to code a smiley face on 8*8 matrix? - Arduino Forum
Sep 1, 2017 · An Arduino pin can't sink 8*15mA of current. You need an NPN transistor, MOSFET or driver IC for the cathodes. Once you understand how scanning the LED matrix works, learn how to use for loops and two-dimensional arrays.
