Basic trigger module for up down counters
The ‘basic trigger module’ works as a basic controller for up and down counters or seven-segment display drivers. It has 3 switches for up count, down count, and reset. Up switch increases the count and down switch decreases the count and the reset switch resets the count to zero. How does it work ? All...

THIS CIRCUIT IS EXTREMELY SENSITIVE TO DARKNESS. EXPERIMENT THE CIRCUIT IN A HIGHLY ILLUMINATED ROOM.
LED GLOWS EVEN IN LESS DARKNESS. Use torch light if the LED glows in less darkness. You can adjust the sensitivity of the circuit using a variable resistor in place of R3-300Ohm. Try this circuit with other resistances as well, for example, 1K, 10K and 100K, etc.
+9V TO 60V PWM 2.3A SOLENOID VALVE DRIVER USING DRV101
The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners. The DRV101 module is also ideal for driving thermal devices such as heaters and lamps. PWM operation conserves power and reduces heat rise, resulting in…
