Led effect circuits attract the attention of many people, including me, especially these days there is great interest in led and led circuits, blue, white, led prices are not as expensive as before, 12 leds are used in the led effect circuit, the transition of effects and speed settings are made with buttons, the microcontroller used is Attiny2313
The circuit has the source Bascom AVR .bas, .hex, .bin source codes and the printed circuit pcb drawing I prepared with sprint layout 5. There are 14 effects, you can use the simple serial port programmer I shared before to load the hex file to the attiny2313 processor. (Attiny2313 Programmer com port rs232 ponyprog)
The circuit works with 5V DC voltage. The speed value is 10-250 and the default value is 100ms. The speed setting is set with the S2 and S3 buttons. When the S2 button is pressed, 10 is added to the default value.
S1 button; Next effect
S2 button; Decrease speed
S3 button; Accelerate.
S2 and S3; button; Previous effect

15A Motor Speed Control Circuit Attiny45 PWM
Used in motor speed control circuit microcontroller atmel attiny45p exit number 5 Kubla connected to pin opto pc817 pc817 output while the engine is controlled as isolated MOSFETs have bs170 and irlz34 Attiny45 Pb4 leg control signal number 3 is entered. Circuit driven by motors up to 15 amps. MOSFETs are driven by PWM method pwn frequency 1.8 kHz
Attiny45 LM2940CT5 regulator used to supply PWM motor control Attiny45 value you can use the 7805 Bascom project’s source code schema, and PCBs have drawings
