Wemos d1 and blynk

Hello I have a wemos d1 and have connected to the chip following 1fototransistor 1dht11 1ds18b20 1reedschalter 1bmp280 The wemos d1 should have a fixed ip and the reed switch should send an email when the reed switch is pressed and in blynk a led light can someone help me with the code I can not get it out

Sounds like a complicated project for someone who doesnt know how to code.

Start really really realllly simple by getting your reed switch to light up an LED widget using the beginner examples.
