DC motor
If you want to control an DC motor that can run forward or reverse you can do that in many Read more
convert resistance to voltage
Converting resistance to voltage in electronics sometimes are so important because many electronics device such as microcontroller only can read Read more
arduino, keypad, lcd, wires (Small)
this project is about how to display characters to LCD directly by keystrokes/pressing keypad. Read more
The LM317 device is an adjustable voltage regulator capable of supplying more than 1.5 A over an output-voltage range of Read more
Build small project need small display too. That's why small touch screen comes in handy. We will demonstrate how to Read more
voltage divider
Unfortunately, your arduino can sense voltage only from 0V-5V. That’s why voltage divider come in handy. Read more
