Atmel AT89C2051 Single Chip Microprocessor Circuit Notes : * This is a actual simple appliance of a distinct dent chip (IC1). * The array ability accumulation is affiliated on terminals T1 &T2. While the ambit diagram specifies 3v/4.5v battery, the allotment ULN2803 needs 4.5v-5v array to get able operation. * About-face SW2 allows the PCB [...]
With aloof eight genitalia and a battery, the accouterments can hardly be simpler. Ambit access is a aftereffect advancing beeline from the akin of affiliation of its capital components. The temperature sensor IC is either a DS1621 or DS1631 (Maxim). This 8-pinner includes a complete agenda temperature sensor/thermostat with I2C output. With the adapted commands, [...]
This simple circuit can be used as an aid for sensing the distance between the rear bumper of the car and any obstacle behind the car. The distance can be understood from the combination of the LEDs (D5 to D7) glowing. At 25cm D7 will glow, at 20 cm D7&D6 will glow and at 5cm [...]
Emergency Lighting Schematics Circuit The circuit of automatic emergency light presented here has the following features: 1. When the mains supply (230V AC) is available, it charges a 12V battery up to 13.5V and then the battery is disconnected from the charging section. 2. When the battery discharges up to 10.2V, it is disconnected from [...]
