Bidirectional Serial communication between Raspberry Pi and Arduino Let’s make things a little bit more interesting. You’ve seen how to send data from Arduino to Raspberry Pi. In this part you’ll see how to talk from Raspberry Pi to Arduino. Thus you’ll have both sides of the communica...
// initialize serial communication at 115200 bits per second: Serial.begin(115200); //set the resolution to 12 bits (0-4096) analogReadResolution(12); } void loop() { // read the analog / millivolts value for pin 2: int analogValue = analogRead(1); ...
Unfortunately, the LED may turn on when it is not supposed to due to a floating voltage on pin 11. To overcome this problem, you may need to connect a1 Megaohmresistor between pin 11 and GND. Serial Communication: A Way To See What Your Arduino Is Doing ...
Serial Monitor Output: Conclusion In this article, I have shown you how to setup SPI communication between two Arduino boards and SPI read example for RFID with Arduino Uno board. I hope you found this article informative. If you did, please share it with a friend who likes electronics and...
