The circuit is made with a very simple antenna coil pcb drawing, there is no need to use an additional coil, there is one transistor in the circuit, I think the circuit will work more efficiently with the equivalent bf series transistor instead of bc547. A 5 cm wire can be used for the antenna…
White LEDs in lighting and more powerful power LEDs are now used in all areas. We shared a lot earlier project led lighting led lights for bikes in the current article, I will discuss the application. Led the supply of the bike from the alternator getting additional batteries not need to use the picture above…
The circuit is a simple circuit that can be an example in the field of medical electronics, medical electronics, based on the LM2904 op-amp integrated circuit. Heartbeat and pulse detection is done with the LTM1550-01 photo sensor, sound is given with the buzzer on the circuit and light warning is given with the LED. 4…
Infrared (IR) Receiver-Transmitter Project In this article, infrared (IR) transceiver circuitry will tell. The objective of making the circuits perform on-off remote device. The circuit operation briefly as follows; The first press of the button on the transmitter circuit, infrared LED light sends 38 kHz. This eye catching light in the receiver circuit by-pass relay…
Previously, “Night Lamp with White Led, 20 pcs economical lamp with white LEDs project and 220volt with 19 pcs white LED energy saving lamp practices were shared’ll talk about saving bulb on the application made by removing the original parts. Half-6 white LEDs used LEDs on the power supply directly to 220v mains voltage are…
I have previously shared a 4 channel logic analyzer circuit made with PIC18F4580. The 8 channel circuit is made without using a microcontroller. In the USB Logic Analyzer circuit, FT245BL is used for the USB interface. Other auxiliary integrated circuits LM339 op amp and CD4069, CD4093 are fed directly via the USB port without the…
