used Six LED’s and NE555 timer IC and 4017 Counter IC. But one thing is different I used. This is Variable Power supply. We can change input voltage from 3V to 12V. The speed to glowing up step by step of LED’s is directly proportional to input voltage. when we increase the input voltage then speed of glowing LED’s will increased and when we decreased input voltage then speed of glowing LED’s will decreased.

Theory: A low-pass filter is an electronic filter that passes low-frequency signals and attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. It implemented using a resistor and a capacitor. The actual amount of attenuation for each frequency varies from filter to filter. A low-pass filter is the opposite of a high-pass filter. The below circuit diagram illustrates a simple ’RC’ low-pass filter. The range of frequencies passed by a low pass filter

integrated circuit operational amplifiers that combine the advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip. The CA3140A and CA3140 BiMOS operational amplifiers feature gate protected MOSFET (PMOS) transistors in the input circuit to provide very high input impedance‚ very low input current‚ and high speed performance. The CA3140A and CA3140 operate at supply voltage from 4V to 36V (either single or dual supply). These operational amplifiers

Laboratory Handbook Stage 1 Semester 2 ENG1030M Electronics Applications Project Electronic Applications (ENG1030M) Module overview This laboratory based single module (100 hours total) consists of one 3 hour session per week and has 3 main parts. Each part involves practical and written work‚ these are shown below in chronological order. You should be advised that that the lab sessions use up 36 hours and therefore you will be expected to use the remaining 64 hours in background work

Final Report FOR REMOTE CONTROL ROBOT WITH CELL PHONE LINK December 12‚ 2005 Submitted By: Justin Schaper Richard Lienou Michael Area Sudhendu Raj Sharma Advisor: Dr. Carl Latino Abstract Team Robot Cell Inc. developed a working model of a one-way control link between a user control device (joystick) and a dumb robot (RC car) using two cell phones. The joystick provides the user with proportional control over the speed and steering of the RC car from a remote location. Included

programmable; that is‚ each output may be preset to either level by entering the desired data at the inputs while the load input is LOW. The output will change independently of the count pulses. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. A clear input has been provided which‚ when taken to a high level‚ forces all outputs to the low level; independent of the count and load inputs. The clear‚ count‚ and load inputs are buffered

to use will be the one with the largest range of resistance over the temperature range in consideration‚ as this will mean more accuracy. This is because a greater range in resistance will result in a greater sensitivity; a greater difference in voltage per degree temperature change. There are 3 different sensors available to me‚ and I will simply address these as Sensor 1‚ Sensor 2 and Sensor 3. I need to measure the range of resistance that each sensor offers‚ from roughly 0¡ÆC to 100¡ÆC. However

transistor is biased in voltage divider mode. the out put is taken from the emitter which is fed to the SCR gate. The transistor biasing circuit acts as a voltage follower to the SCR. When the protective circuit is closed‚ the transistor works on near cut-off stage. It acts as a open circuit. When the protective circuit is opened or cut because of breaking of security‚ all the input voltage falls on the base of the transistor. Now transistor conducts. The output voltage at emitter triggers the SCR
