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...
Layout Control Mother Board
The layout control motherboard is designed to facilitate the management of various sections of a layout. It features a microcontroller that connects to the MRNet bus and multiple slots for inexpensive control and sensor boards. All control and sensor boards...
Motorized Video Camera Mount
The camera rotator circuit utilizes a 2716 EPROM to store a logic value table that governs the motor driver (H-bridge) circuit. The schematic illustrates the EPROM data. By employing the EPROM, a significant number of discrete gates are eliminated. The...
Motor control with tachometer
The generator output is rectified, filtered, and applied between the positive supply voltage and the base of the detector transistor. This configuration provides a negative voltage that reduces the base voltage as the speed increases. During normal operation, if the...
Microcontroller Clapper Switch
For those who prefer convenience, it is possible to turn the bedroom light on or off without leaving the bed simply by clapping hands. This concept inspired the design of a clap-activated light control system. Various clap switch projects can...
Direction and speed control
This circuit functions similarly to the one depicted in Fig. 57-4. The key differences include the placement of the field across the rectified supply and the armature being positioned within the SCR bridge. Therefore, the field current is unidirectional while...
PROGRAMMABLE_TIMER_SEQUENCER
The circuit diagram of this programmable sequencer can be utilized for various timing applications. An audible tone is generated before the start of each interval, while a seven-segment LED display indicates the current interval number. A buzzer sounds again just...
Secured room access system
Security is a primary concern in daily life, and an access control system is a crucial component of a security framework. The microcontroller-based digital lock described here is an access control system that permits only authorized individuals to enter a...
