Arduino Uno R3 is one kind of ATmega328P based microcontroller board. It includes the whole thing required to hold up the microcontroller; just attach it to a PC with the help of a USB cable, and give the supply using AC-DC adapter or a battery to get started. The term Uno means “...
Arduino Uno MQ-3 Alcohol Sensor – Connection Diagram Now that we knowhow the MQ-3 alcohol sensor works, we can connect all necessary wires to an Arduino Uno and see how it functions. We'll start with the analog component and then go on to the digital part, which is pretty simple. To...
Inbuilt LED (13):This pin is used to activate the LED. IIC (A4, A5):These pins are used for supporting TWI communication. AREF:This pin is used to give reference voltage to the input voltage Difference between Arduino UNO and Arduino Nano The Arduino Nano board is similar to an Arduino ...
First of all, see the simple add-on hardware setup for Arduino Uno. Note that this approach of course works for other models of Arduino as well. The hardware is in fact nothing but a regulated linear power supply backed by a super capacitor, with a crude power-down detector circuit. The...
