Arduino Relay controling sketch witch multiple button types (mono-/bi-stable, reed switch), multiple actions (click, double-click, long-click) and MySensors protocol (Serial and MQTT) Topics. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins. Four screw holes allow the Shield to be attached to a surface or case. The maximum length and width of the 4 Relays Shield PCB are 2.7 and 2.1 inches respectively. Both connect to the same TWI interface to allow you to create a chain of TWI devices. 2 TinkerKit TWI: these connectors (4-pin in white) are routed on the Arduino TWI interface.2 TinkerKit Outputs: OUT5 and OUT6 (in orange), these connectors are routed to the Arduino PWM outputs on pins 5 and 6.2 TinkerKit Inputs: IN2 and IN3 (in white), these connectors are routed to the Arduino A2 and A3 analog input pins. When we use an ESP8266 or ESP32 microcontroller with an operation voltage of 3.Connecting TinkerKit modules can simplify the creation of a project or a prototype. The relays are controlled by the following Arduino board pins: Relay 1 = Arduino pin 4 Relay 2 = Arduino pin 7 Relay 3 = Arduino pin 8 Relay 4 = Arduino pin 12 The shield features several TinkerKit input/output and communication interfaces. It is used to programmatically control on/off the devices, which use the high voltage and/or high current. The relay module has 3pin screw terminal. A relay is a programmable electrical switch, which can be controlled by Arduino or any micro-controller. Connect the IN pin (Input pin) of Relay to Arduino digital pin D3. Connect the GND pin of Relay to Arduino GND. The shield doesn't need external power: it will be provided by the base board, through the 5V and 3.3V pins of the Arduino board used as base. Connect the Vcc pin of Relay to Arduino 5V. Press the switch /push button (select button / connected to arduino pin 11) Now using the two buttons (mins and hours (connected to arduino pin 8. Single pole chargeover contact maximum 30 V DC 2A Initially when the circuit is switched LCD will display adjustable timer By Technical Hub.after 2 secs the lcd will again shows the.
