Datasheet TRIAC BT151 General Description Glass passivated thyristors ina plastic envelope, intended for use in applications requiring high bidirectional blocking voltage capability and high thermal cycling performance. Typical applications include motor control, industrial and domestic…
Lightning Rod Arrester surge Panels Both have different functions. It is better to install both. The lightning rod solves the problem of direct strike.Surge arrester overcome indirect struck problem. Lightning rod function for lightning strikes…
A digital filter system in principle has a diagram block as follows: [caption id="attachment_5166" align="aligncenter" width="600"]Digital filter System[/caption] In practice, the system needs some additional details in order to be implemented with a microprocessor or…
An analog signal can be converted into digital and vice versa. This technique has several benefits. In this paper only discussed examples of applications that are LTI (Linear Time Invariant). Here are examples of some…
Problems: Want to raft amps using a CT 18 VAC transformer But after passing the Spull diode so 34 VDC The circuit is a full-wave bridge rectifier, with the following schemes (source): The signal…
Here is an example of a bird's voice generation using the Arduino Nano microcontroller (ATmega328) The code is taken from http://120.107.171.121/~tywua/sub/ISAR/Chirp.ino, apparently from a professor's website at National Changhua University of Education, Taiwan. [caption id="attachment_5146"…
Making flashing LEDS is one of the simplest ways to demonstrate the timing capability of microprocessors. Here are some techniques you can do: Timer interruptions Standard Arduino delay Delay from FreeRTOS Standard Arduino Delay Delay…
Dry cabinet is useful for storing objects that must be stored at low humidity. For example camera and camera lens. Besides Dry cabinet, you can also use dry box. The main difference: the dry cabinet…
In this article outlined analysis of heart rate signals. A heart rate signal is obtained from the pulsesensor sensor. This Sensor has been discussed in some of the previous articles: Heart Rate Sensor Heart Rate…
Electronic devices require a power source, one of which is an adapter. The need for electrical devices is usually expressed in voltage and current, e.g. 12 volts, 5 amperes. One of the most confusing problems…
Here's a quick article to create a digital controller without too many theories: "PID without PhD" The article writes a fairly complete digital handbook, discussing from digital control theory to source code, minus Rotary Encoder…
Simulation stages of digital signal processing with LTSpice, and compiler C This document focuses on showing the occurrence of processes at each stage and integration of those processes, not discussing system optimization or subsystem. Preparation…
Potentiometers can be used as a source of voltage as a signal to be inserted into a microprocessor system such as Arduino. The Bandwidth of a potentiometer needs to be measured to determine whether an…
Here are some of the display types that are often used for Arduino-based microprocessor systems: Dot Matrix 16x2 Dot Matrix 20x4 E-Ink Display Oled TFT/IPS LCD The interface used to display is: Parallel communication Serial…
