– LOFI BRAIN Arduino-compatible controller with SENSORS TESTING script flashed in
– Sensros: potentiometer, light sensor, button, distance sensor HC-SR04
– Actuators: LED, DC motor
Upload Sensor testing script to LOFI Brain`s Arduino.
Test no. 1 – Light sensor + LED
LIGHT SENSOR (PHOTORESISTOR) connected to INPUT1
LED connectet to OUTPUT1
How it works:
Depending on the ammount of light detected by the light sensor the LED shines with a corresponding brightness. If you cover the light sensor with your hand the LED will turn off (almost) completely.
Test no. 2 – Button + LED
BUTTON connected to INPUT2
LED connected toOUTPUT2
INPUT2 is programatically connected with OUTPUT2 but the signal from INPUT one is reversed – maximum value on INPUT2 gives ZERO value on OUTPUT2.
Test no. 3 – Distance sensor HC-SR04 + buzzer
DISTANCE SENSOR plugged into it`s LOFI Brain socket.
Buzzer gives pulsing squeacky sounds with tempo corresponding to the distance measured by HC-SR04 distance sensor.
Test no. 4 – Potentiometer + voltage meter + DC motor
POTENTIOMETER connected to INPUT4
VOLTAGE METER connected to OUTPUT4
DC MOTOR connected to M2
Value measured by INPUT1 is directed to M1 mototr controller output and OUTPUT4
