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. Unzip the file...
