even during the urban phase they had a local ceramic tradition coexisting with the harappan pottery .
नगरीय चरण में भी उनकी एक स्थानीय मृत्तिकापात्र निर्मित करने की परंपरा थी , जो हड़प्पा मृत्तिकापात्रों के साथ - साथ चल रही थी ।
sites in czechoslovakia have yielded numerous fired - clay figurines in the form of humans and animals which are perhaps the earliest evidence of ceramic art .

googlthe main components of the project are at89c52 microcontroller, ir sensor (ir transmitter and ir receiver) and leds. the basic connections required for 8051 microcontroller involve crystal, reset and external access. in order to use the on-chip oscillator, the 8051 microcontroller requires an external clock. this is provided by a crystal oscillator. an 11.0592mhz quartz crystal is connected to xtal1 and xtal2 pins with two 22pf ceramic capacitors connected to it. the reset circuit of the microcontroller consists of a 10k resistor, 10uf capacitor and a push button. all the connections of the reset circuit are shown in the circuit diagram. external access pin is used to access external memory when it is connected to ground. anyway, we are not going to use any external memory here. so, connect this pin to vcc via a 10k resistor. the next hard ware we are going to connect is the ir receiver. we are going to connect the 8 ir receivers to port 0 pins of the microcontroller. in order to use the port0 as i/o port, we need to connect external pullup resistors to the port 0 pins. after that, connect the output of the ir receiver i.e. anode terminal of the photo diode to port 0 pins. cathode terminals of the photo diodes are connected to supply. also, a 3.3k resistor is connected between the anode terminal and ground. the next part of the circuit is ir transmitter. ir transmitter is not a part of the microcontroller connections as the only job of the ir transmitter is to continuously emit infrared rays. hence, connect the 8 ir transmitters with corresponding 8 current limiting resistors of 470 ohms with a power supply. finally, we need to connect the leds. we need to connect the led’s with the help of transistors to the port2 of the microcontroller. the base of the 8 2n2222 transistors is connected to the port 2 of the microcontroller while the emitters of the transistors are connected to ground. an led along with a series current limiting resistor of 100 ohms is connected to the each of the collector terminal of the transistor.e translet
