Top3 Electronic Project With BC547 Transistor

Top3 Electronic Project With BC547 Transistor 

hello - friend today I am going to show, 3 different use full home mad electronics project with bc547 transistor| I am going to make, 1 fire alarm with bc547 | 2 noise detector with bc547 | 3 RGB effect with bt136 |

about

1 fire alarm with BC547 | very easy circuit diagram I am using just 3 parts 1 bc547 2 or photodiode 3 BT136

| UM35 Siren Generator use just siren driver you can use different siren generator | BT136 pin 1 Terminal  1 | pin 2 Terminal 2 | pin 3 Gate. Used to trigger the SCR  pin 1 common Connected to Phase or neutral of AC mains 

pin 3 On-state Gate open voltage: 1.4v...to....6v max  | Max Terminal voltage 4Amper Max load Voltage is 600v || or photodiode pin 1 anode pin 2 cathode to infrared signal out 

project 1 fire alarm parts details

• 1 bc547
• 2 3.5mm led
• 3 100 ohm resistor
• 4 ir photodiode 
• 5 BUZZER
  
• 6 9V BATTERY

about

so amazing effect RGB LED line strip, auto controller, feeling multicolor effect auto change color like red green blue purple yellow pink orange gold like all color this circuit 2-way work multicolor effect & chaser I am trying to make this project very easy few component use BT136 3.5mm multicolor led 1n4007 diode 9v battery RGB led strip | 

1. BT136
2. 1N4007 diode
3. 3.5mm multicolor led
4. 9v battery
5. RGB LED strip /220v DC

work 3.5mm multicolor led use for RGB strip driver bt136 to use for led blinking switch  diode use for common anode | how to make this connect with bt136 gate connect multicolor led  cathode 3led same connect multicolor anode 9v battery (+) bt136 terminal 1 to connect RGB out bt136 terminal 2 common (-) diode connect RGB common (+)

project 2 AC 220V BULB RGB effect with BT136

parts details

• 1 RGB LED 3.5mm
  
• 2 AC 220V BULB X3
• 3 220 ohm resistor
• 4 BT136
  
• 5 9V BATTERY
  

noise detector driver this useful project you can find hide any noise you have audio amplifier connect this driver can you boost the output sound | circuit diagram just use 4 parts | electret mic 1.5v max | circuit driver 3v..to...5v max |
project 3 noise detector driver circuit

parts details

• 1 electret mic
• 2 bc547 -- c1815
• 3 resistor 1m -- 10k -- 120k
• 4 capacitor 10uf/50v
• 5 3.5mm led
