Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible ... The series resistor R1 sets the ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module ... and use an external 5VDC power supply. If higher current loads are to be ...

They feature analog pins for reading analog components (e.g., potentiometer, flex sensor ... voltage and current ratings are 7 to 12V and 1A only. The Arduino Nano and Uno are equipped with ...

Perhaps you don't have indoor plants to take care of, or you're not interested in knowing what the current temperature ... with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...
