But [Playful Technology] wanted to control the hands with an Arduino directly and, in the process, he shows us how these modules work. If you’ve never studied the inside of these clock modules ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

[Jason]’s breakout board provides 3 isolated clock outputs on SMA connectors. A header connects to an Arduino, which provides power and control over I2C.

Next, you’ll need an Arduino board, which will serve as the brain of your weather clock. You’ll also need a motor shield to control the movement of the clock hands, and a Wi-Fi module to ...

In this article you will learn how to make a digital clock using Arduino and the DS1307 RTC IC. What is DS1307 IC actually? Well, it is a Real Time Clock (RTC) IC that is simple to use, low cost and ...

Each servo motor requires a PWM signal to control its position, and with 28 servos needed for the clock, the Arduino Mega’s capacity was quickly exceeded. To overcome this limitation ...

Alarm clocks are cheap and abundant, but they’re pretty boring. If you want to make your own, Instructables user Paranoid Legend shows you how to build one with an Arduino. The alarm clock is ...

Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and GND to the ground rail. For the data connections, wire SDA to Pin 10, SCK ...
