About a month agoo I asked a few explanation on blind controller circuit design, up now i did focused on mechanical parts of my rubber press and now these are ready, i turned myself...
Radar using laser and microcontroller will u pls help me and provide me the necessary info. -Mail from VV Here are some pages in the web that may be useful in your study …
“Imagine you have a radio receiver and you wish to display the receiving frequency. As you know the oscillator in a radio receiver works 455 kHz or 10.7 MHz above the receiving frequency. The...
This is the Photo of a RTD 3-W Mains Powered Temperature 4-20mA Transmitter. The Circuits and PCB are here RTD PT100 Transmitter and Multiplexer.The Circuit RTD-Pt-100-Transmitter. We can classify Transmitters as shown below. The Measured Parameter...
When you have to buffer and invert the polarity of mV input levels. This is the circuit you can use, as OP07 has uV offset. R9 and R10 can be 100K 1% MFR or...
The Measured Value and The Setpoint are two inputs to a Control System. The Measured Value is the Amplified input of a Transducer or Sensor for some Parameter that needs to be controlled. It...
Many many thanks for this quick reply again. We are also experimenting with stobing the LEDs very fast using digital out of the MCU’s I/O to kind of PWM the LED to calibrate it...
