Blynk Slider control intensity of LED & Display value on Gauge.

This video is for beginner's of Blynk app. Slider position value is sent to Gauge as well as PWM pin (D1) of NodeMCU, where LED is interfaced. Intensity of light is controlled according to position of Slider. Gauge is displays slider value.

Thanks! Very nicely explained. can we blink LED using this by taping just a button in blynk app?

[@kurox4588]

slider level changes led once and then gets stuck. no more changes after that until disconnect & reconnect. no idea why- i turned on send values on release only to avoid spamming the servers but it did not help
