Bridges connected motor speed control circuit 12f629 controller based on the PWM method and the motor is driven integrated outputs 2N7002 MOSFETs reinforced with assembly language prepared by the source. Asm,. Hex code and eagle prepared with diagrams, printed circuit board files there.
Fully solid-state, bi-directional output (without relays)
Lightweight materials SMD (surface mount)
10 A Maximum motor current (with MOSFETs)
Auto LVC (Low Voltage Cutoff) for 6 ~ 12V input voltage
For the smooth and efficient control of high-frequency PWM (3kHz)
1 A low dropout BEC (Battery Eliminator Circuit)
Author motor control circuit used for speed control model aircraft projects
Aircraft Motor Speed Control
Whilst there are many commercially reversible speed controllers available, most are designed for high performance model cars or boats, and therefore are large and expensive. I wanted a lighweight ESC for fitting into a small scale boat or submarine.
Fully solid state, bi-directional output (no relay!), Lightweight SMD (Surface Mount Device) construction, Up to 10A maximum motor current (with suitable output FETs) Automatic LVC (Low Voltage Cutoff) handles 6~12V batteries, Throttle neutral at standard 1.5mS, or 1.37mS for offset stick, Safety Arming. Motor won’t start until throttle is set to neutral High frequency PWM (3KHz) for smooth and efficient control 1A low dropout BEC (Battery Eliminator Circuit)

PIC16F84A Simple LED Ciruit
A very simple application is carried out with the PIC16F84 PIC programming can be useful for beginners People
Summer program after program with MPLAB ASM extension Alt + F10 on the keyboard and save when you press Go MPLAB ASM code translates into HEX codes (they say). If there are errors in the ASM code you ERROR command shows errors. When you double-click ERROR command shows the incorrect line. After correcting errors in the compilation process is done again. After the compilation process of the program HEX codes are registered, where the ASM code occurs.
