Four Segment LED The four Segment LED includes four seven segment LED’s to display 4 values at a time, Since there is only 12 pins needed to display 4 different values, the LED uses a method called Multiplexing, where one digit is shown at a time, but switched fast, so Read more…
Basics Infrared is a form of light radiation, except it lies outside the visible light spectrum for humans. Since IR is undetectable to the human eye, it makes it a good candidate for wireless communication. Many products such as remote controls utilize infrared technology. In infrared communication, a infrared receiver converts Read more…
A 7 Segment LED includes 7 pieces to display numbers and letters, in this project we will be controlling one with a Infrared sensor, to display numbers and even do math. We need to connect our IR receiver again. Review the instructions here Once you have your IR receiver connected, Read more…
After completing the first LED project, we can now use an Infrared Sensor to control our lights. We need to connect our Infrared receiver to our breadboard, each Infrared receiver has 3 pins, one for signal, one for ground, and one for VCC(power), the Arduino board has multiple ground pins, Read more…
An LED stands for “light emitting diode” It gives off light and uses little power. It has two states, on and off, the state it is in can be controlled by “digitalWrite” To start programming your LED you will need to make a variable for the pin number you are Read more…
Arduino is a open-sourced electronics platform. It can be used for many projects. Arduino is coded in C++
