One simple way of displaying numerical data from an Arduino (or any microcontroller for that matter) is through the use of seven segment displays. But what are seven segment displays and how do you connect an Arduino to a seven segment display?
Transistors! What are they and how do they work? Let’s explore these relatively simple devices with so much potential for greatness.
This here will be a quick tutorial on flip-flops. We’ll look at the different types and some of their applications. But first, what is a flip-flop?
Perhaps you’ve been powering your Arduino projects from the computer through the USB cable all this time and you feel it’s time to finally let your Arduino free of its tether. Perhaps you would like to know how to power your Arduino from a battery. No despair! It’s really easy and I’ll show you in detail.
This is a continuation of a series of posts on simple experiments I’m performing with my new Bus Pirate v4.0. Click to see me trying out the bus pirate v4.
I’ll connect up 3 EEPROM ICs on a breadboard and interface with them through the I2C bus. The particular ICs I will use are 24LC256 EEPROM chips each with a 256Kbit or 32KByte capacity.
