The BT139 is a TRIAC thyristor, which is a type of semiconductor device that can use to control alternating current (AC) power. TRIAC thyristor BT139 is a four-quadrant device, meaning that it can conduct current in either direction. The BT139 has a peak inverse voltage (PIV) of 800 volts and a current rating of 16 amperes. It is a sensitive gate triac, meaning that it can be triggered with a low gate current.

The CD4050 hex buffers are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors. These devices feature logic level conversion using only one supply voltage (VDD). The input signal high level (VIH) can exceed the VDD supply voltage when these devices are used for logic level conversions. These devices are intended for use as hex buffers, CMOS to DTL/ TTL converters, or as CMOS current drivers, and at VDD = 5.0V, they can drive directly two DTL/TTL loads over the full operating temperature range.

8051 is an 8-bit family of microcontrollers developed by Intel. This microcontroller was also referred as a system on a chip because it has 128 bytes of RAM, 4K bytes of ROM, 2 Timers, 1 Serial port, and four ports on a single chip. The CPU can work for only 8 bits of data at a time because 8051 is an 8-bit processor. In case the data is larger than 8 bits then it has to be broken into parts so that the CPU can process conveniently.
