Try L Chika with raspberry pi
Things necessary
- LED (light emitting diode)
- Resistance (1kΩ)
- Jumper wire (male-female)
- bread board
- raspberrypi 3 set
Wire
See here for GPIO pin numbers.
- GPIO pin 23 of raspberry pi3 → LED anode (longer leg)
- LED cathode (shorter leg) → Resistance
- Resistance → GND
Program in Python
- Install wiringpi.
pip install wiringpi
- Create and execute the following program.
led_test.py
import wiringpi
import time
out_pin = 23
wiringpi.wiringPiSetupGpio()
wiringpi.pinMode(out_pin, wiringpi.OUTPUT)
for i in range(0, 5):
wiringpi.digitalWrite(out_pin, 1)
time.sleep(1)
wiringpi.digitalWrite(out_pin, 0)
time.sleep(1)
- If the LED blinks for 10 seconds, it is successful.
