Microcontroller measures heart rate through fingertip
The reflected infrared (IR) signal detected by the photodiode is sent to a signal conditioning circuit, which filters out unwanted signals and amplifies the desired output.
The circuit begins with a photodiode that captures the reflected IR signals. The photodiode operates...
Password Based Door Locking
Security is a prime concern in our day-to-day life. Everyone wants to be as much secure as possible. An access control for doors forms a vital link in a security chain. The microcontroller based Door locker is an access control...
Flashflex Microcontroller Control Of Character Lcd Module
