Educate the world | JK electrocorps | IEEE Project center in chenna i The automatic bike turning signal system based on a microcontroller (MCU) available in the market is expensive and difficult to program. Here is a simple and inexpensive circuit that you can build yourself. The circuit is used to indicate left or right turns for a bike or two-wheeler. Two identical circuits are needed, one for left and one for right Circuit and working for Automatic Bike Turn Indicator Circuit diagram of the bike turn indicator is shown in The circuit consists of ADXL335 accelerometer sensor, voltage regulator 7805 (IC1), LM393 comparator IC (IC2), two NE555 timer ICs (IC3 and IC4) and a few other components. ADXL335 is a small, thin, low-power, complete 3-axis (X, Y and Z directions) accelerometer with signal-conditioned voltage outputs. Only Y direction of ADXL335 is used in this project. The device measures acceleration with a minimum full-scale...
