Learn: how HC-SR501 motion sensor works, how to connect motion sensor to Arduino, how to code for motion sensor, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided
This Instructable will show you how to build an Arduino using only an ATMEGA328P IC. If you are new to embedded systems, you will find all the steps needed to do this explained completely and clearly. Along the way, you will learn how to unbrick a previously programmed 328P and how to...
It goes without saying nothing forbids to replace the LED with a relay in order to drive loads the most important. But let’s see in detail the circuit: The operation is quite trivial: by touching the two contacts of the sensor “SENS” with hands for example, the weak current flowing ...
When converting your design from an Arduino Uno to a raw ATmega328 chip it is helpful to be able to relate the pinouts on the ATmega328 to the connections on an Arduino Uno. The following pinout diagram has been relabeled to show the Arduino Uno equivalent functions: An example might be ...
