The mobile phone signal is in the frequency range of 0.9 to 3GHZ. Schottky diodes have the unique property of being able to rectify low-frequency signals, with a low noise rate. When an inductor is placed near the RF signal source, it receives the signal through mutual induction. This signal is rectified by the Schottky diode.

A reset push switch (operated by the quizmaster) cancels the bleeper and switches off the LED so the circuit is ready for the next question.\u003cbr\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003e\n\u003cbr\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: start;\"\u003e\u003cimg alt=\"Fastest-Finger-First-Indicator-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Fastest-Finger-First-Indicator.jpg?v=1632808394\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions (cm) L x W x H : 20 x 15 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/CzUZ27YpK-Q\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF KIT","offer_id":40708845404341,"sku":"LGKT032","price":499.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE KIT","offer_id":40708845371573,"sku":"LGKT032_R","price":599.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/FastestFinger-First-Indicator-DIY-Kit.jpg?v=1632809337"},{"product_id":"dc-motor-speed-controller","title":"DC Motor Speed Controller","description":"\u003cstrong\u003eDC Motor Kit\u003c\/strong\u003e is meant for controlling the speed of a 12 volt DC motor.

Motor Control Using A single Switch","description":"\u003cstrong\u003eDC Motor Control Switch \u003c\/strong\u003euses a Single Switch DC motor that will be run in the clockwise or anti-clockwise direction and stop using a single switch. It provides a constant voltage for the proper operation of the motor.\u003cbr\u003e \u003cbr\u003eThe kit \u003cstrong\u003eDC Motor Control Using a Single Switch\u003c\/strong\u003e consists of three units- 555 as a monostable vibrator, as the decoder and flip-flop unit to hold the state and shift the bits and the motor drive unit to drive the motor in both the direction. All the controls of the motor are with the single switch that is forward-backward and stops. The 555 unit gives a trigger pulse on each press of the switch. To prevent false triggering 555 timers are used in monostable mode. Every trigger pulse changes the logic state of the output of the CD4017 which gives high polarity on different pins (+9V). The potential divider circuit distributes this voltage (formed by two equal 10K resistors V=4.5V). \u003cbr\u003e\u003cbr\u003eThese \u003cstrong\u003eMotor Control Kit's\u003c\/strong\u003e signals are fed to the motor driver IC L293D to operate the motor in both the direction. The first press of the switch operates the motor in the forwarding direction by giving 4.5V to the signal pin. Similarly, the second press of the switch operates the motor in a backward direction by giving 4.5V to the signal pin. The third press of the switch will reset the IC CD4017 to give 0V output to both the signal pins and thus the motor stops.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv style=\"text-align: start;\" id=\"p_info\"\u003e\u003cimg src=\"https:\/\/i.postimg.cc\/RCHX9mV7\/LGKT048.jpg\" alt=\"DC Motor-Control-Using-A-single-Switch-block-diagram\" border=\"0\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions (cm) L x W x H : 20 x 15 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/v5pPgB5dgGI\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF KIT","offer_id":40708846583989,"sku":"LGKT048","price":799.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE KIT","offer_id":40708846551221,"sku":"LGKT048_R","price":999.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/dc-motor-control-using-a-single-switch.jpg?v=1632830483"},{"product_id":"simple-water-level-indicator","title":"Simple Water Level Indicator","description":"\u003cstrong\u003eSimple Water Level Indicator\u003c\/strong\u003e \u003cstrong\u003eUsing Transistor\u003c\/strong\u003e is easy to build four led for indication of levels in sequence also a buzzer is used to indicate overflow condition.
