details required for… Atmels 89C52 Microcontroller A/D D/A converter Keypad LCD display(Or LED Display) 5V Regulated power supply. Temperature & Humidity controller using PID control algorithm implemented using Atmel’s 89C52 microcontroller for a AHU...
Digital Interface Part Two
Continuation of Digital Interface Discussion, only my part of the communication here. This will help you understand some common methods and issues.
Digital Interface Third Part
Only my Messages are combined here to create paragraphs. Related to Interfacing an Embedded System to external circuits. Pull up means a resistor connected from a point to +V. Pull Down is Resistor connected...
Opamp Supply on Buffered Virtual Ground
When a Inverting Opamp Configuration is at a steady state, we say the Inverting Input is at a Virtual Ground. That means it is at 0V w.r.t to the dual power supply ground, but...
CJC or Cold Juction Compensation
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...
The Return of Bright LED
From my Thunderbird archives. it may be interesting to read, maybe you may learn a thing or two. Many thanks for your quick reply – much appreciated. The FET solution is new to me,...
