Et lille LED tester projekt
Jeg kigger på NET for en LED tester og efter at have set en ide, ville jeg bygge denne tester fra nul
forsyninger:
Trin 1: Schemat
For at teste en LED har du brug for en nuværende generator.
LM317LZ databladet giver et kort, Se grundlæggende idé hjemmeside
www.robotroom.com/LED-Tester-Pro-1.html
ingen kode tilgængelig fra dette websted
Princippet er derfor at måle flere spændinger ved LED'ens terminaler
VH anode spænding VL katodespænding og subtraherer dem (VH - VL)
Derefter måles spændingen ved terminalen af modstanden, der krydser strømmen af LED IL og divideret med dens værdi R (VR / R = IL)
Trin 2: Kode Arduino
For Arduino-koden blev den grundlæggende idé defineret. Jeg ønskede et display på OLED-skærmen
biblioteket er til en ssd1306
github.com/adafruit/Adafruit_SSD1306
Til måling af forskellige spændinger se
http: //www.instructables.com/id/Arduino-OLED-Volt …
For forskellige menupunkter se
it-edukacija.eu.hr/multidruino/default.html
For at oprette ikoner se
javl.github.io/image2cpp/
vi består testen på et testkort
