11 PIN TIMER RELAY WIRING DIAGRAM
ESP8266 NodeMCU Relay Module - Control AC Appliances
Dec 18, 2019Wiring a Relay Module to the ESP8266 NodeMCU Board. Connect the relay module to the ESP8266 as shown in the following diagram. The diagram shows wiring for a 2-channel relay module, wiring a different number of channels is similar. Warning: in this example, we’re dealing with mains voltage. Misuse can result in serious injuries.
Countdown timer using Arduino, LCD 16x2 i2c & 4x3 Keypad
Feb 18, 2020Description: Countdown timer using Arduino-in this tutorial, you will learn how to make an advanced level Countdown timer based on the Arduino, 16×2 i2c LCD, and a 4×3 keypad countdown timer is entirely different from the rest of the countdown timers available on the internet. This countdown timer can be used as the end product. With the help of this Countdown timer, you can
Automatic Plant Watering & Irrigation System - Circuit
Pin 1 and Pin 3 are the power and ground whereas pin 2 is the contrast pin on the LCD which controls the contrast and connected with the potentiometer. It must be kept in mind while connecting LCD is that digital pins from Arduino and data pins from LCD has to be connected in correct order otherwise LCD will display only garbage on the screen.
IR Transmitter and Receiver Circuit Diagram
Aug 20, 2015Output Pin 3 of the 555 Timer IC has been connected to IR LED using 470 resistor and a push button switch. Whenever we press the button, circuit emits modulated IR at 38 KHz. A 100uF capacitor is connected across the supply to provide the constant supply to the circuit, without any ripple. IR Receiver Circuit Diagram

Arduino Keypad: Interfacing with 4x4 Matrix
Using a keypad is an upgrade over using buttons for input on your Arduino project. Actually, a keypad is a set of 12 or 16 buttons wired so that the pin usage is reduced. In this tutorial, I will explain how a keypad matrix works and how to use it with an Arduino. Contents1 Buttons
EDIS Ignition Control
EDIS Ignition Control with MegaSquirt-II. The Ford EDIS System. Ford's Electronic Distributorless Ignition System (EDIS) is an ignition system that does NOT require a cam position signal can function with just a variable reluctor crank position sensor and a 36-1 tooth wheel (36-1 means '36 teeth minus one', and refers to 36 evenly spaced teeth, one of which has been removed).
BigTimer - Scargill's Tech Blog
Jan 02, 2021Node–RED is a fantastic and powerful yet easy to use programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. For more information on Node-Red go to the Node-Red site. BigTimer is my own creation and is (IMHO) the most powerful and best-ever, most comprehensive timing node for Node-Red, providing a general purpose timer as
