NodeMCU Wifi ESP8266 Dual Dimmer Board with Arduion Uno (Atmega328P)
What is it?
Wifi Dual dimmer board to control home appliances like fan or light to make your home a smart home, by controlling them through your smartphone. Dual Dimmer board is a Wifi based remote control switch/dimmer product. Designed and developed to control lights and/or fans. Using this board the lights and fans can be controlled via mobile phone which you use regularly. This board is not just to switch ON/OFF the light, you can also vary the intensity of light from 0 to 100%. You can connect and control two loads in an instant. It also has a feature to connect virtual switch as a potentiometer to vary the intensity of light in two way mode with respect to the mobile phone.
Why did you make it?
It is a DIY product can be used by both tinkerers and non-tinkerers. Tinkerers can make their own code and reprogram it.
What makes it special?
It is compatible with Arduino. It has an onboard USB-UART converter to program using micro USB cable from PC.
Works directly with AC power 100 - 240 V AC 50-60 Hz. Product firmware can be updated/reloaded/changed as per user requirement. It has onboard USB to UART converter on board for programming purpose. Board is Arduino compatible. Two Triac outputs, to control the light/Fan. Triac output can handle up to 2 Amperes of current. WiFi with MQTT or HTTP protocol. Basic Firmware to enter SSID and password to connect to the router Firmware has the ability to control device through HTTP and MQTT mode. Push Button on board Provided for Restart and Factory Reset function. Does not require external neutral for output. Output power up to 480 Watts AC per load. MECHANICAL SPECIFICATION
Mechanical Dimensions of PCB are 110 x 55 x 20 mm (Length x Width x Height) Mounting Holes M3 size Safety Warning:
Note that, this board shall be powered by AC 230V with required current. Work and handle carefully with AC power as it is harmful and dangerous for human beings. Touching live wire or powered ON board is danger and not advisable, it may cause death, please avoid it.
AC mains are very dangerous -- Even a 50 V AC supply is more than enough to kill you. Please Switch off the mains before you make or change connections, be very careful. If you are not sure of anything related to the AC supply lines, please call an electrician ask and him to help you with it. Do not attempt to interface with mains unless you have adequate training and access to appropriate safety equipment. Never work on high voltages by yourself when you are alone. Always ensure that you have a friend/partner who can see and hear you and who knows how to quickly turn off power in case of an accident. Use a 4A Fuse in series with the input to the board as a safety measure. A basic Wiring diagram is available on our Instructables page and GitHub. Please refer to it.
Fire Hazard: Making wrong connections, drawing more than rated power, contact with water or other conducting material, and other types of misuse/overuse/malfunction can all cause overheating and risk starting a fire. Test your circuit and the environment in which it is deployed thoroughly before leaving it switched on and unsupervised. Always follow all fire safety precautions.
