PCF7936AS IC Integrated Circuit

Tutorial: How to Use PCF7936AS

The PCF7936AS is a 4-channel integrated circuit multiplexer/demultiplexer. It is useful for managing multiple signal sources on a few pins.

What you need

• PCF7936AS
• Arduino
• Resistors (10kΩ)
• 16-pin Connector

Steps

1. 1. Installation: Connect the PCF7936AS to your Arduino using a 16-pin connector.
2. 2. Connect pins S0 and S1 of the PCF7936AS to two digital pins of your Arduino.
3. 3. Connect pins IN0-IN3 to four digital pins of your Arduino.
4. 4. Connect a 10kΩ resistor between the VCC and GND pins of the PCF7936AS.
5. 5. Verify the correct pin configuration in the datasheet.
6. 6. Write an Arduino code to select different channels and read signals.
7. 7. Test the functionality with a simple sketch.
8. 8. Test the various channels to ensure they work correctly.

Example code

```void setup() {  pinMode(2, OUTPUT);  pinMode(3, OUTPUT);  digitalWrite(2, LOW);  digitalWrite(3, LOW);}void loop() {  digitalWrite(2, HIGH);  delay(1000);  digitalWrite(2, LOW);  digitalWrite(3, HIGH);  delay(1000);  digitalWrite(3, LOW);}```

Mini project
