Sawtooth wave generator circuit using UJT

In the Figure 1 circuit used Q1 is UJT to connects with VR1(potentiometer), VR2 and C1. They acts as a sawtooth wave generator circuit, by C1 to charge and discharge. Then, current from the 5V power supply through VR1 and R2. This current and voltage that increase and reduce, cause… Read more »
