Analog Datalogger Based On T89C51RD2 -  I had requested by head of the department of Applied Physics to design a low-cost device for the workshop on "Building Simple Instrument for Physics Lab" held in August 1, 2003 at the Faculty of Science, KMITL.  The workshop has 29 participants.  All of them are from high school physics teachers.   __ Designed by Wichit Sirichote

Analog inputs for ATtiny26 -  Study the Analog to Digital capabilities of Atmel ATtiny26.  This check circuit uses only 3 inputs.  Of course you can may changes to use more inputs  __ Designed by Vassilis Stergiopoulos

Analog to Digital Conversion notes -  This chapter shows how to connect an analogue signal to a PIC. 
An analogue signal is similar to a sine wave and is generally less than 5v    (5,000mV) in amplitude.  Low-level signals are generally expressed in mV, to make them instantly recognisable and easy to talk about.   __ Designed by Colin Mitchell

Analog-Input serves any microcontroller -  20-Dec-01 EDN-Design Ideas - The simple ADC in Figure 1 is perfect for getting analog signals into a purely digital microcontroller.  Using just five surface-mount parts, you can assemble it for less than 50 cents   (1000], which is approximately half the cost of a single-chip-ADC approach in the same volume.  Moreover, this design takes only one pin from the microcontroller to operate __ Circuit Design by Steven Hageman, Agilent Technologies, Santa Rosa, CA

Anti-crosstalk for Network I/O -  PIC Project  This example is using a PIC16F628 - a real favorite of mine recently.  Among its other features is a full function hardware UART.  This circuit was part of a servo motor controller circuit using a 74LS07 in the design.  One    (left over) section of this chip is used to provide the open collector output drive.   __ Designed by Luhan Monat - Mesa Arizona

Anti-symmetric FIR filter slashes resource use -  EDN-Design Ideas - 12/22/2014    An anti-symmetric FIR design with the same implementation advantage as a symmetric - FIR filters used for signal manipulation in the digital domain have either a symmetric or anti-symmetric impulse response, i.e., where N is the order of filter.   Anti-symmetric filters have a phase-shift property and are widely used as phase shifters.  Consider an FIR filter of order N, with N + 1 coefficients.  For a symmetric FIR filter of order N, by exploiting the symmetric nature of the filter, the memory and multiplier requirements are scaled down by almost 50%.   This  Design Ideas extends the same advantage to anti-symmetric filters. __ Circuit Design by Punithavathi Duraiswamy

Arduino based line following robot in 10 minutes -  Line followers are one of the most prominent kinds of robots.  They have existed for a very long time, however, the technologies used for building them have changed rapidly.  Earlier, controller boards the size of bricks were used, but now they have shrunk and become tremendously powerful.  Now, technology allows you to build a line follower in just under 10 minutes if you have the parts for it.  So enjoy building this quick and easy line follower.  Have fun with this DIY hacking tutorial! __ Designed by © EETech Media, LLC
