This are some hands on IoT projects which are done using the Bolt IoT, breadbaord, resistor, LDR, jumperwires, buzzer for alert system
STEP 1The most first thing is connection. So I"ll tell you step by step how to do connections.
1} Connect 4 one side to buzzer with the use of jumper wires.
2} Connect the 3v3 to another leg of breadboard with the use of jumper wires.
3} Connect the A0 to breadboard and another leg of buzzer is connect to breadboard.
4} Connect the 10k resistor.
5} Connect the LDR sensor to breadboard.
STEP 2- Now moving to the coding part of the system.
Hardware part
Breadboard:- The Functions of a Breadboard. A breadboard is a platform you can use to build and test electronic circuits, usually without having to do any soldering. Certain parts of the breadboard are wired together so that electricity can flow from component to component in orderly rows.
Buzzer:- A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.
LDR:- These resistors are mainly used when there is a need to sense the absence and presence of the light such as burglar alarm circuits, alarm clock, light intensity meters, etc. LDR resistors mainly involves in various electrical and electronic projects.
Resistor 10k:- A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
Jumper wires:- The term "jumper wire" simply refers to a conducting wire that establishes an electrical connection between two points in a circuit. You can use jumper wires to modify a circuit or to diagnose problems in a circuit. The following steps outline how you can safely use jumper wires in different electrical applications.
