The crypto notify is used to detect the price drop or increase of Bitcoin so we will be setting a fixed selling price thereby if the price increases more than selling price then buzzer is switched on. If the price is less red led is switched-on, if equal orange led will switched-on.

Supplies

Hardware needed:-

BREAD BOARD-mini

Bolt-IoT(wifi module)

Led's x 2 Buzzer x 1

Jumper wires

software needed:-

bolt IoT account

Fritzing for schematics

Step 1: Connect the Buzzer to the Bolt-iot

the buzzer is connected to the bolt it using a breadboard

the negative end is grounded and the positive end is given to pin 1 of bolt IoT

Step 2: Connecting Led's to Bolt-iot

the two LEDs positive pins are connected to 2,3 pins of the bolt-IoT and the negative pins are grounded

Step 3: Whole Connection

in this video you can see the connection of whole circuit

Step 4: Python Code for Thr Bolt-IoT
