CIRCUIT IDEAS touch signal is connected to the counter/ decoder via a resistor and clock input CK is connected to the counter/decoder via a frequency generator.
Line frequency signal is taken through R4 at pin 2 of IC TT6061A.
At zero crossing, the triac (BT136) triggers to drive a 200W bulb.
The 6.
8V power supply is taken directly from mains through resistors R1 and R3, diode D3, capacitor C4, and zener diode and fed to power-input pin 3 of the IC.
Capacitors C1, C2, and C3 connected between touch input pin 4 and touch plate Pin Assignments of IC TT6061A Pin No.
