Arduino – PWM frequency and timers
What is PWM Pulse width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is controlled by turning the …
Module – RC522 – RFID/NFC transciever
BESTELLEN Informatie (ENG) The RC522 RFID module based on MFRC522 IC from NXP is one of the most inexpensive RFID options that you can get online for less than four dollars. It usually comes with a RFID card tag and key fob …
Arduino – CAN Bus communicatie
Het is mogelijk een arduino te gebruiken met een CAN Bus interface, met CAN Bus kan je datalijnen gebruiken tot ca. 500m, en apparaten werken peer-to-peer (ipv master – slave) dat is erg interessant! Wat je nodig hebt is een …
