Introduction to Voltage Dividers Voltage dividers are very important to circuits monitored by microprocessors. Important to realize, microprocessors will usually handle 3.3 volts, or 5 volts. With this in mind, the voltage of the circuits they control can be much higher. In this case, we want to measure Read More »
Introduction to the PIR motion sensor We will use PIR Motion Sensor (Passive Infrared) to detect movement. We can use the PIR sensor for security If the sensor detects movement, we can sound an alarm. Another use for the PIR sensor is to automatically energize a light when detecting Read More »
Introduction to the Photo Resistor (LDR) A photo resistor (LDR) will change it’s resistance based on the lighting we apply to this component. Also known as a Light Dependent Resistor, we use them in our every day life. We use photo resistors to energize night lights in our house. Furthermore, Read More »
Introduction to Arduino Vape Box Mod In this document, I will explain how I built my own arduino vape box mod. This box will be based on PWM (Pulse Width Modulation). Be aware that the purpose of the document is just to explain how I built my own box. Read More »
Introduction to the Binary Numbering System Simply put, the Binary Numbering System is a base 2 numbering system. The only numbers available for use to count in binary are 1, and 0. You can think of this in many ways: True/False, Yes/No, or High/Low. Computers work by Read More »
Introduction to Diode Rectification A diode allows current to flow in one direction. We use diode rectification to convert an AC signal to a DC signal. Another use for a diode is for circuit protection to prevent a reverse polarity connection (+ and – reversed). Just be aware there Read More »
Introduction to the photoelectric resistor The photoelectric sensor can be used to detect the intensity of a light source. This can be used to detect night and day such as you would see in a night light in your house, or a security light on your garage. In industrial applications, Read More »
Introduction to the Ultrasonic Distance Sensor The HC-SR04 ultrasonic distance sensor has a variety of applications: 1) It can be used in robotics for a robot to detect the distance to an object that it needs to avoid. 2) The sensor can be used to measure the water level in Read More »
Introduction to Arduino (Microprocessor Introduction) This document will give you a Microprocessor Introduction to the Arduino Uno. There are other variants of this board, such as the Mini, Nano, Yun, Leonardo, and Esplora. In addition, there are many off brand products such as Einsboard and Funduino. Although the Read More »
Introduction In short, a transistor is a switch. This is much like the switch you use to turn on the lights in your home, but with a lower DC voltage, and a smaller amount of current (amps). Instead of the switch being physically moved to turn a load Read More »
