Here you will find a huge collection of electronic schematics: audio amplifiers, radio and IR transmitters, antennas, diy kits and more.
Servo Motor Controller
Mar 15th
This is the simple basic design of Servo pulse generator. It uses the CMOS IC 7555 in the Astable mode to generate pulses to drive the servo motor. The circuit can be suitably modified to get pulses of sufficient length.
Crystal Controlled 38 kHz IR Transmitter
Mar 14th
This is a precision 38 kHz Infrared transmitter using MOS integrated circuit uPD 6121.It uses the NEC transmission format ideally suited for remote operation in TV, VCD Player etc. The NEC transmission format includes leader codes, custom codes (16 bits), and data codes (16 bits).The frequency of oscillation is determined by the Crystal. The IR LEDs connected to the output emits IR pulses at 38kHz.The circuit is ideal for most IR Sensors since these are designed for 38 kHz pulsed IR rays IC uPD 6121 Datasheet
Display Driver
Mar 12th
This display driver circuit shows how a Seven Segment Display is driving with the help of the 5 stage Johnson decade counter IC CD4033.The IC has counter and decoder in one package. It converts the Johnson codes into Seven Segment Decoder output to drive the common cathode display. The display shows the counts in the form of numerical display. CD4033 Datasheet (more…)
