The circuit consists of Arduino; you may use your favorite Arduino board, a 16x2 LCD display to showcase the unknown resistor value, a potentiometer to adjust contrast level of LCD display. This is the very useful project for the electronics beginners. If you have any circuit related query, you may interact through comments, I'll be most happy to help! Besides, it is very easy and still useful. Using some mathematical calculations, voltage drop at the node and known resistance value can be interpreted to find the unknown resistance value. 2. 3. Les ohmmètres analogiques (aussi dits « mécaniques ») sont peu couteux, car de conception simple, et peuvent mesurer aussi bien des résistances faibles (de 0 à 10 Ω) que plus importantes (de 0 à 10 000 Ω). You will have to trace the antenna by yourself,,,,it will be most probably terminating from a transistor lead…. The scale of the meter in this project should have 0-500 μA .

Conseil : si vous ne comptez pas investir dans un seul ohmmètre, sachez que vous pouvez acheter un multimètre qui, outre la résistance, vous permettra de mesurer la tension ou l'intensité d'un courant. So, we need to do analogue to digital conversion, fortunately Arduino has built-in 10-bit analogue to digital converter. Les ohmmètres numériques présentent les mêmes plages de mesure, mais l'avantage est qu'il y a une fonction automatique de choix de la plage : vous les branchez sur un circuit et il se règle tout seul. This line in the program states that, if the sensor resistance goes below threshold value output turns ON and vice versa. Today I am going to show you, 555 audio simple ohmmeter circuit. Cet article a été rédigé avec la collaboration de nos éditeurs(trices) et chercheurs(euses) qualifiés(es) pour garantir l'exactitude et l'exhaustivité du contenu. In this post we are going to construct a simple digital ohmmeter circuit using Arduino and 16x2 LCD display. Let’s see how to make an ohm meter first and then we move to other circuit ideas. Il envoie dans un circuit donné un petit courant à l’aide de deux touches métalliques et mesure ainsi la résistance du circuit en question. You can change the known resistor value in the circuit, but if you do so please change value in the program also. Cet article a été consulté 74 484 fois.

The value of the reference resistance can be adjusted in the program by replacing the value of Rrefer. Comprenez bien que si vous mesurez la résistance d’un élément en place dans un circuit donné, vous n’êtes pas sûr(e) d’avoir la mesure réelle du composant en question, ne serait-ce que parce que les fils ou les liaisons ont une résistance propre. Un circuit ayant une résistance nulle (0 Ω) permet une circulation sans entrave du courant, ce qui correspond bien à cette idée qu’il n’y a aucune… résistance au sein du circuit. Yes . The main objective of this project is to use the resistance value read by arduino to do some useful projects, for instance, fire alarm, where the change in resistance value of thermistor can be easily detected or automatic irrigation system where, if the resistance of soil goes high the microcontroller can trigger the water pump. I have modified the Receiver Circuit and Removed the LED and Connect a Relay. Un circuit à tester n’a nul besoin d’alimentation, puisque l’ohmmètre, muni de sa propre alimentation (piles) s’en charge. The 5 volts that the Arduino provides gets divided up between the 2 resistors, depending on the value of the 2 resistors. Comme vous mesurez une résistance, mais la remarque ne va pas de soi, le placement des deux touches (positive et négative) importe peu, ce qui ne serait pas le cas pour une tension ou une intensité. You can adjust the range according to your wise. The shunt resistance in this project can be any general propose meter. The motto of this article is not just making an ohm meter to measure the resistance; your multimeter can better do the same. How this ohmmeter circuit works is that the 2 resistors in series form a voltage divider circuit. You may have encountered this problem. If you try to measure a low value resistor in mega ohm range in your multimeter, certainly you get error values. Transistor T1  works as a constant current generator which passes  a know current through the resistors which resistance is to be measured.
