NOTE:
When using the TSOP1738 IR Receiver Module in a Beam Break application it is necessary to interrupt the 38KHz signal being generated by the IR Emitter.
An example is a 'People In/Out Counter', where the beam break is used to detect a person entering or leaving a room.
If the TSOP...
These circuits are for converting a 4mA thru 20mA Loop signal to 0V thru +5V , suitable for an ADC input or a +10V
When using a LM358 OPA, the closest specified lowest swing is approx 20mV above 0V.
If a full' 0V thru +5, +10V is required use a suitable rail to rail OPA.
Take care when...
hi,
The circuit is designed for a 12F683 PIC, it outputs QA and QB [ quadrature signals] also two other pins output a 2 Phase non overlapping clock pulses.
The purpose of the project is to be able to drive the QEA and QEB Input pins of say 18F2431/4431, to enable bench testing of Quadrature...
hi,
Demo for Oshonsoft HID USB with a VB5 PC Terminal
Download and unzip, includes the VB5 source code and other files.
The Demo requires the Visual Basic 5 run time files to be installed in the Windows/System folder.
These run time files are free web downloads.
