tinkerers, hobbyists, makers, and beginners. You can feed an Arduino board a set of instructions for it to carry out certain tasks. It is able to read the inputs and turn them into an output, for example, it will read a finger on a button and turn on an LED. ...

A very useful type of diode, it offers a stable reference voltage. They work in reverse bias and break down when a certain voltage is hit, but when the current flowing through the resistor is limited, a stable voltage is produced. Zener diodes are mainly used in power supplies to provide...
A: The Pi is like an Arduino on steroids – more powerful CPU and OS, but lacks the precise timing and analog inputs of an MCU. The two are complementary depending on your specific needs. Q: How difficult is the Raspberry Pi for kids to learn on? A: Thanks to kid-friendly environmen...

Resistor (10k -2nos.) Capacitor (0.1uf) LED Breadboard Circuit Diagram Working of the Hardware Debounce Circuit The circuit is consists of twoNand gates(74HC00 IC) forming aSR flip flop. As you can see in the circuit diagram whenever the toggle switches to the A side the outpu...
You can see the remnants of some of my previous repair attempts, and the extra MOSFET and pullup resistor at top right. Now, to open or shut the door, I have to hold down the button on the right and press the left button, rather like using a shift key on a keyboard. It seems ...

Now that you have your resistor with the proper value, you can place one end of the pull-up resistor to VCC and one end between the input device and the MCU. Congratulations! You now know what a pull-up resistor is and how to use one. Some microcontrollers such as Arduino boards, and...
that is, a resistor whose value can be altered. A potentiometer you might get will be a dial, so you spin it to create different degrees of resistance. It might not be obvious at first or written on it, but you can use diagnostics in the Arduino software package to figure it out ...
