INTERPRETATION OF RESULTS In the first experiment of the course‚ there are three objectives that are needed to be proven through different materials and procedures. The first is objective A‚ where we are to identify the values of the resistance and capacitance by measuring and computing. There are no problems about this part since the values are in agreement; meaning it only got a little amount of percent error. Next‚ objective B wants us to familiarize with the oscilloscope by setting it up to

There can be no doubt that the twentieth century is one of the most remarkable in human history for its previously unparalleled rate of scientific discoveries. In fact‚ there were so many new gadgets invented and discoveries made in the last century that it’s difficult to write the list down. However‚ I think I can say ten innovations or technologies that have had the greatest influence on humanity—both positively and the negatively. First of all‚ I want to remember penicillin: this drug (eventually

CIRCUIT IDEAS REMOTE-CONTROLLED FAN REGULATOR Dr C.H. VITHALANI sing this circuit‚ you can change the speed of the fan from your couch or bed. Infrared receiver module TSOP1738 is used to receive the infrared signal transmitted by remote control. The circuit is powered by regulated 9V. The AC mains is stepped down by transformer X1 to deliver a secondary output of 12V-0-12V. The transformer output is rectified by full-wave rectifier comprising diodes D1 and D2‚ filtered by capacitor C9 and regulated

Should children watch a lot TV? I think children should not watch a lot of TV. Though TV in moderation can be a good educator as there are a lot of good educational programs which help children to learn the alphabet‚ numbers‚ about wildlife‚ time spending in front of TV should be supervised and limited depending on the age of child. To begin with‚ unlimited time spending on watching TV has negative influence on children health: less physical outdoor activities‚ sore eyes. A lot of children

hat binoculars do to improve your vision‚ this personal sound enhancer circuit does for listening. This light-weight gadget produces an adjustable gain on sounds picked up from the built-in high-sensitivity condenser microphone. So you can hear what you have been missing. With a 6V (4×1.5V) battery‚ it produces good results. As shown in Fig. 1‚ a small signal amplifier is built around transistor BC547 (T1). Transistor T1 and the related components amplify the sound signals picked up by the condenser

ABSTRACT Ultrasonic range finder using 8051 A simple ultrasonic range finder using 8051 microcontroller is presented in this project. This ultrasonic rangefinder can measure distances up to 2.5 meters at an accuracy of 1 centi meter. AT89s51 microcontroller and the ultrasonic transducer module HC-SR04 forms the basis of this circuit. The ultrasonic module sends a signal to the object‚ then picks up its echo and outputs a wave form whose time period is proportional to the distance. The microcontroller
