Arduino code for 4 to 16 channel 5V Relay module . This is code for 4 to 16 channel 5V Relay module for Arduino In this video you will learn the details description of 4 Channel relay module. Dosto aj ki is video me main ap ko yeh btao ga k ap kis tarha sy Arduino Uno or HC-05 Bluetooth module ko use krty huy kis tarha sy ghar k kisi b electrical sy drive hony wali cheez ko control kar sakty hai. This is a 5V 8-Channel Relay interface board, Be able to control various appliances and other equipment with large current. Another step closer to controlling things in the house by voice. In this example, we will connect the relay module with Arduino in the normally open state. The two capacitors are C1 100μF 25V and C2 470μF 16V. Arduino UNO board You will learn the meaning of lower trigger and high trigger. 1. The RX and TX pins of the Arduino connect to the TX and RX pins of the HC-06 Bluetooth module, respectively. The Bluetooth module receives data from the paired Android smartwatch and triggers the relay based on the received data. Find this and other Arduino tutorials on ArduinoGetStarted.com. you should also read getting started projects of arduino. The connections for connecting the relay module with Arduino are very simple. It can be controlled directly by Micro-controller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).The protective case is made by high grade acryl, which provides excellent protection, with fashion appearance. Hardware Requirements. (You can modify the Arduino code and connections.) So the armature overcomes the tension of the spring and is attracted to the core, thus closing the moving contact of the armature and the normally open contact (or you may say releasing the former and the normally closed contact). The Arduino Bluetooth Relay 4 Channel App supports the control of a 4-channel relay module via Bluetooth (HC-05, HC-06, HC-07 ect.) Install “ARDUINO – BLUETOOTH 8 CH.”. When power is down from the channel pin the relay will shutoff to NC from NO. Learn how to use relay with Arduino, how relay works, how to connect relay to Arduino, how to code for relay, how to program Arduino step by step. 8_channel_relay_low VCC: Connected to positive supply voltage (supply power according to relay voltage), GND: Connected to negative supply voltage, IN1: Signal(LOW Level) triggering terminal 1 of relay module, IN2: Signal(LOW Level) triggering terminal 2 of relay module, IN3: Signal(LOW Level) triggering terminal 3 of relay module, IN4: Signal(LOW Level) triggering terminal 4 of relay module, IN5: Signal(LOW Level) triggering terminal 5 of relay module, IN6: Signal(LOW Level) triggering terminal 6 of relay module, IN7: Signal(LOW Level) triggering terminal 7 of relay module, IN8: Signal(LOW Level) triggering terminal 8 of relay module. There are two fixed contacts, a normally closed one and a normally open one. Add a certain voltage to the coil and some currents will pass through the coil thus generating the electromagnetic effect. This video shows how to control 16 AC or DC load using the 16 Channel Relay and Arduino. modules. Description. This is why we can control a 220V appliance by simply controlling it using the 5V Arduino. Bluetooth Low Energy (BLE) Module (Generic). The code behind this is pretty simple.

Relays are suitable for driving high power electronic devices such as lights, electric fans and air condition. Combine Arduino with Bluetooth and relay, and control your AC appliance with a smartphone app. See my video Showing you how to solve the problem. If it lowers to a triggering voltage, the relay will pull in. The closing and releasing of the contacts results in power on and off of the circuit. 8 Channel relay home control with web browser. That's all. Each submodular of the relay has one NC(nomalclose), one NO(nomalopen) and one COM(Common). I know the same company that makes these 8ch relay boards also makes 16 channel boards. Yeh video app k lye bohat he mofeed sabat hony wali hai. It can be controlled directly by Micro-controller ( Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). 4.The power source and the relay system power can be divided. NO (Normally Open): A normally open configuration works the other way in which the relay is always open until you send a signal from the Arduino to the relay module to close the circuit. Triggered at high level means a forward voltage exists between signal triggering terminal (INx) and negative supply voltage. Also shown is a typical optical isolated 12V 8 channel relay board. You can use the Arduino’s pin 13, pin 12, pin 11 and pin 10.
