Does Arduino Mega have internal clock?

The 8-bit board with 54 digital pins, 16 analog inputs, and 4 serial ports. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560….Warranty.

What is the main application of relay?

Application Of Relay Relays are used for isolating a low voltage circuit from high voltage circuit. They are used for controlling multiple circuits. They are also used as automatic change over. Microprocessors use relays to control a heavy electrical load.

What can you do with an Arduino relay?

It is used to programmatically control on/off the devices, which use the high voltage and/or high current. It is a bridge between Arduino and high voltage devices. When you are making projects that are connected to mains voltage, you need to know what you are doing, otherwise, you may shock yourself.

Is it possible to control a 24V DC motor?

yes you can. but to control a 24v DC motor you use a driver “relay, IC or H-bridge”. you use the io port as a switch only to open the driver. the 24v will be applied to the DC motor through the driver.

Are there any Arduino compatible motor drive boards?

Yes there are Arduino compatible Motor drive boards and shields. Note however that with the official Arduino Motor Shield the abs max supply is specified at +18 volts (need to look at why that is, the logic and op-amp are both run off the +5V rail from the Arduino); and the VIN-CONNECT link HAS to be cut.

Can a light bulb be connected to an Arduino?

For the light bulb, we MUST use another power source (high voltage and/or high current), which can burn Arduino. Therefore, we CANNOT connect the light bulb directly to Arduino’s pin. We need to use a relay between Arduino’s pin and light bulb to protect Arduino from high voltage/current. Please note: These are affiliate links.
