The next challenge is interfacing with 12 button matrix keypad and serial LCD . In this challenge, the micros need to read the keypad input and display it on the serial LCD. If the # key is entered after the … Continue reading
The next challenge is interfacing with serial LCD and DHT11 Ambient Humidity & Temperature sensor . In this challenge, the micros need to read the proprietary one wire signal from DHT11 sensor and display it on the serial LCD.
The next challenge is proximity detector using the ultrasonic sensor. In this challenge, the micros need to capture the PWM signal transmitted by the ultrasonic sensor. The distance of the nearby object is translated on to four LEDs. The micros … Continue reading
The next challenge is interfacing with RFID module and Buzzer. I purchased the RFID module from SeeedStudio. It is a 13.56 MHz RFID reader capable of ISO14443 type A. For this test, the micro would regularly send the get_read_ID command and parse … Continue reading
The second challenge is Controlling servo motor using potentiometer. For this test, the micro read the analog voltage drop across the potentiometer and drive the servo motor according to the voltage change. For the Arduino, I used the Knob example … Continue reading
