NE556 Dual Timer IC Mini Servo These are Carbon Film Resistor

These are Carbon Film Resistor with a value of 11k ohm 1/4W and tolerance of ±5%

M3 x 5mm+20mm Male to Female Thread Brass Hex Hexagonal Standoff Spacers

The 120E SMD Resistor is a conventional thick film chip resistor and is a type of surface-mount resistor

The temperature can be monitored more precisely with the LM35 than with a thermistor

NE556 Dual Timer IC Mini Servo These are Carbon Film ResistorIn one IC package, the 556 IC contains two distinct and independent timer circuits. It works in astable or monostable mode, and timing or delay can be modified with an external resistor capacitor combination, just like the 555 timer IC. The NE556 dual monolithic timing circuit is a highly stable controller and capable of producing accurate time delays or oscillations. Features Low Turn off Time Max. Operating Frequency >500kHz Tuning from microseconds
